Thanks for watching! If you want to know more about Tangaroa - check out our website onboardtangaroa.com. See you next week! Same Time Same Place! Cheers Blaine and Janis
I feel your pain... you are not alone and it is nice to see another couple so dedicated to working together on a boat. Take some time to enjoy each other's company. You both deserve it. Cheers from Nova Scotia!
Thanks so much. We actually really enjoy working together on our project...our retirement home. Sometimes it is overwhelming but most times it's like eating an elephant...one piece one project at a time.
Tangaroa said "Tiaki mai i ahau, maku ano koe e tiaki" If you look after me, I will look after you. The boat looks good, and I agree who ever welded her did a fantastic job.
What a wonderful saying. We may have to mount that in the wheelhouse. Is that OK? She def needed and deserved some love and we are happy to give it to her. Janis
@@OnboardTangaroaSeatrial Don't forget that any tender you have for the boat should be named Punga who was Tangaroa's son. Wishing you all the very best in your endeavours.
Hey, I just discovered your channel! What a project!!! But such a cool boat!! Can't wait to see the finished product! Cruise around the SJI so we can see!!
Thank you for your reply. You’re a hell of an engineer and good luck to you and your wife on getting her finished. Will be watching your videos. Happy holidays to your family.
Always makes me smile to see a Marine Travel-Lift because they're made just north of me in Sturgeon Bay, WI. Also where I used to build aluminum Palmer Johnson Yachts so I know EXACTLY what you're seeing, smelling...and tasting working on that hull. ;)
Funny enough, Janis and I met working on Galileo. She was a 123' Aluminum Palmer Johnson Ketch! I was engineer on that yacht for four years. We loved it. Such a nice yacht. That is one of the main reasons we wanted an aluminum yacht. Blaine
All our customs boats are bare aluminium here in Australia . As son of a marine engineer, hull builder . And master class 5 holder . There going to be more worms in that can that I would take on . Good on you guys .
The hull has actually been pretty good. Other than that aft deck there are no major issues. That was the only thing we were concerned with. Much of the mechanicals and electricals will be replaced ultimately. Sorry to hear your father passed so soon after retirement. I had a good friend who passed shortly after retirement as well. That is why we are quitting out jobs and going travelling while we still can. Thanks for watching!
come from a commercial fishing family in Australia and we own nothing but bare aluminium boats and is the only way to go, we beach them, launch them from beaches up to 30 foot long, run crab pots and nets up the sides. paint is for rich people with no clue who want to look fancy is all.. We have a 10 foot aluminium dinghy my old man has had since he was 10 years old and lived full time in the ocean behind many of his trawlers etc, sunk 3 times while being towed, and barnacles so thick took me ages to scrape them off. barely even pitted from the salt from corrosion too. Steel rusts, wood needs to much maintenance and fibreglass can crack in bad weather. Would own only aluminium and no paint except anti foul on the hull...
We love the bare aluminum look and its so easy to maintain. Definitely happy we did it. I think there are a lot of people who think aluminum just wastes away in seawater.
Back in the early 90s we were able to tour the Palmer Johnson boatworks in Sturgeon Bay Wisconsin. They were at the finishing stages of a large motoryacht for a unnamed party. They were fairing the hull with buckets of "fairing compound". Bondo! For us, that was not something we had thought of when looking at a beautifully finished hull.
Funny enough, Janis and I met on an aluminum 123' Palmer Johnson ketch and had a repaint done at Orams marine in Aukland, NZ! Definitely some filler there! Blaine
@@OnboardTangaroaSeatrial Holy CRAP!! 😆I used to WORK THERE before they closed-up! (thanks a LOT Timmur Muhamed/1000 years of combined employee ship-building experience flushed down the toilet🙄) I still have a gallon of leftover & unopened Awl-Grip pink fairing compound in my basement and a ton of aluminum deck-plating scrap from the engine-room. The drink-coaster on my night-stand is a leftover piece of polished marble from a 123' one-off fiberglass yacht that I dug out of the trash and cut into a square (burning up an $80 bandsaw blade in the process🤭). So cool you met on a PJ. The sport-yachts we built are sleek, beautiful, fast (for their size) and were guaranteed to do 30kts. Good luck from NE Wisconsin. ✌
Hi Bab .n. Blaine we had a Ally 32ft Boat a a friend had the same boat built by same company he painted his boat and we left ours Natural 5 years down line he had those blisters which he had to take all paint off and our boat was still in good nick only problem we had was the dreadful electrolytic which we put a cable right though the whole boat and solved our problem so far so good we had our boat for nearly 15years and the other owner says boat is awesome
Hi guys! Nice to have some people tackling such big project! I myself want to start on my classic Van Lent Feadship this summer i will document it on youtube aswell
Awesome. So glad that other people think like we do. Old yachts have personality and are well built. They just need some love...and a sheet load of work. Cheers janis
I wonder how much weight savings from removing all that bondo and paint and leaving it bare aluminum? love the look of bare aluminum btw, great choice!
When the fair a hull Al Steel even GRP it tends to add a considerable amount of Wt ... Something this size you are talking about 100-150 kg of fairing. Steel boats can be worse still..... Really wt conscious vessels they try to avoid it as much as possible. That means a lot of time on the moulds and mould finish..before laying up. Looking again it could be even more fairing compound 😬
this was just excellent ... I love the raw aluminum look and am very curious how it ends up looking on this style of boat ... the few shots at the end with the nice stripe looked great
It's not body filler it is a fairing compound which is put on most high-end aluminium boats to give a smooth rounded finish then it's painted over with primers and then a good top coat you should have known that when buying i.e. a metal or aluminium boat and what you did to help along was the right thing to do well done its blummin hard work but now that done why don't you paint it yourself you can roller on the paint you will need to put an acid etch paint on first to get the paint to bond onto the metal then away you go anyone can do it it will cost you a bit in paint but saving up is the way to go.
Yeah that's so necessary that sandblast but you know what you should have done with the naked aluminum part is taking 1400 Grit or wet sandpaper and do circles or you get a circle pattern and it nice and shiny the aluminum up and then clear coat it to 3or 4 coats of clear coat and be nice and bright and shiny
Aluminum is one of the most difficult materials to paint. The problem is OXIDES! Aluminum produces a protective oxide layer within minutes and no paint, including zinc oxide primer will adhere well. What I found out is to strip down to the bare metal. Just before you are ready to paint go back and sand or DRY blast an area that you can paint in one hour. Clean off the area with dry air or dry cloth. Do NOT use acetone, water, alcohol or any other cleaner. Anything will accelerate that oxidation process before you had you a chance to paint should be avoided. Repeat the process all the way around. Never use a wire wheel to final prep for paint. The wire burnished surface is terrible for paint adhesion.
Great advice. That is exactly how we painted our bottom but that video is coming up soon. We also just got a new to us aluminum dinghy and put bottom paint on her. We do use alumaprep though or what is called alodine. Cheers Janis
After all that, I think I would have tig welded the deeper pitts and ground them down flush, just so there were no thin spots in that quarter inch plate. Wouldn't have cost much more nor taken much time compared to what you spent already. She is a really nice boat though.
That's my plan for the rest of the hull. Lots of little pits to tackle though. I can weld at anchor. I do not currently have a spoolgun and Tig welding them would just take too much time. A spoolgun is on the wish list though! We will definitely spend the time to make her good. Merry Christmas! Blaine
OK, so I have now seen 3 videos from this series and I seem to be going back and forward in time. That said, every video so far is extremely interesting and I am in awe as to the work you are carrying out - do you know when this vessel will be completed or is it like my boat, an ongoing restoration job.
The timeframe definitely jumps a bit as we have revamped the videos to try and show a complete project. As this ha been ongoing for 4 years now there is some back and forth. This is very much like you describe your boat. I don't feel it will ever be done. There seems to be a never ending list of things to do! Glad you are enjoying the vids. Blaine
Interesting. I'm planning on building an aluminum sailing boat next summer and will not cover it all that much with paint after watching this video. Thanks for the tip.
Happy if we can help someone prevent this type of damage. It's not that you can't get a good paint job on aluminum. It's just harder to maintain and the prep is even more critical.
@@OnboardTangaroaSeatrial Your the second channel that I've seen talk a little bit about it but you did a way more informative job. The other video I saw just mentioned that the paint doesn't like to stick to aluminum after so many years. That channel is Sailing Life on Jupiter. That's the boat that I want. It has spray foam on the inside that is covered by fiberglass. I'm not sure if that will cause the aluminum on the inside to have problems or not.
I am always a bit leary about covering the aluminum with anything that can absorb moisture. I also think about how much effort it would take to prep an area if I had to weld. Spray foam would not be much fun there.
wow thats a huge job.we know how nice it is when its quiet we have a neighbor who does his projects illegal without permits including deforestation and has been dumping thousands of trucks of dirt nextdoor for years and the noise is sometimes incredible.he has friends who work at the county to protect his illegal dumping my guess is they share the profits for dumping.seems everyday some dumb tractor is running.your lucky its quiet again.boat looks good
I did the topside of my 32' Marinette. The best way I came up with was a flapdisk 40-60 grit and a hose. With lots of water I could push hard and the disk wouldn't gum up. No dust. A disk would last hours. Maybe 4 4.5 in disks for the topside. The only corrosion was under the bondo and in the bilge under the tar.
I should add that if you've gone this far you should paint it. Sand a bit by hand or the orbital sander, then undercoat. Roller was great, tip with a 2nd roller no bubbles. I don't know why marine paint needs tipping. Forget tipping with the brush. Put a 5 ft handle on the rollers. Use a high density foam roller for tipping. Unfortunately they fall apart after 20 min. Get lots of those.
I had heard the blasting was good for adhesion. We had not thought about soda blasting to smooth it out though. Maybe a future project? Thanks for watching!
that was a big job, its good that you have the positivity (you will need it). however, how exciting that its stripped back, it appears that the hull is in good shape, excellent news. she has nice lines. watching from australia.
Her lines were beautiful, and we were pleasantly surprised. Hopefully, we will get down your way with her within the next 5 or so years. Circumnavigating Australia is on our bucketlist. Cheers Janis
Bondo uses talcum for a filler and it absorbs water that freezes and cracks and swells. Get the filler without talcum and uses fiberglass instead for a more permanent fix.
Thanks for the advice! We don't plan to ever put paint back on her though. Much easier going to the places and doing the adventures we plan to do with her bare. Blaine
I work in a boat yard and we have 2 of these boats in our yard. They were both extended like this one was. And they both have the same fairing compound problems. Along with fuel tank problems. But I beleive they were both extended by Derektor in ft lauterdale. I have all the paper work from when it was done to the one known as “Garbo” it was done in 1978. They will both eventually be cut up
Fortunately we don't seem to have any fuel tank issues. We have decent access and the ones we have been into look good. If I am not mistaken this extension was done in Mexico. Cheers! Blaine
It had been extended by 13 feer. Good eye. We have never talked about it on video and we don't know when it was done however we are considering making a video about what is on it for tankage and how it affects the location of the props and how Tangaroa drives. Cheers. Janis
I have no interest in sailing the world because of all the nightmare videos I see on youtube, but you tricked me into subscribing because I want to see how you fix this problem. Well done.
I spent 6 years on USN 'tin cans' destroyers. The USN uses a philosophy of PPR (Preserve, Paint, Repair (if necessary)), so a lot of efforts look REALLY FAMILIAR! What is difference between the different types of grit (used many, but someone else paidfor it)? Black magic (tungsten carbide), corn cob, sand... P.S. my first ship (now this comparing is apples to watermellons) we spent FIVE MONTHS IN DRYDOCK! So after 10 days i too can feel your pain...
5 months! No thank you. The paint is off now or at least the majority of it is. Makes maintenance ao much easier. Cheers. Janis Thank you for your service by the way
What you’re describing in this video is known as crevice corrosion and not electrolysis or galvanic corrosion. It’s caused by oxygen poor areas saturated below the paint. Dry blasting would have been faster and the media is reusable. Dry blasting also allows for paint to be applied before a thin corrosion layer forms over the aluminum. You could have also used a softer media to smooth over the rough surface after blasting with sand.
I do call it poultice corrosion which seems to be another name for what you call crevice corrosion. There was also a couple of electrolysis spots on the hull which I showed in the video. They have a completely different look. Unfortunately the shipyard did not allow dry blasting due to the dust production. This guy was the only one they allowed in at the time. As there won't be paint going back on we don't have to worry about the oxide layer reforming. Thanks for the suggestions though. You never know if paint may be a possibility in the future.
Blaine, Janis you guys are the best how interesting. It’s Sunday and I’m watching your videos (hours) instead of my NFL football games. That’s how much you have aroused my interest in your yacht project, guys are awesome. Do you have any videos of the outside or inside of the finished Yacht as of December 2024 today?
Well, if you are from the states we know how important Sunday football is so we are honored 😁! Lol, she is far from finished today but we are trying to figure out how to best do that. The interior is still pretty torn apart as there is still tons of wiring and plumbing to do which goes slowly with full time jobs.
🌟 Guys, you were broadcasted via #messtv onboard a 116-foot super yacht off the coast of St Baths in the Caribbean Crew Feedback. just watch your product values and the final finish of each broadcast. When watching It feels very 2005ish, and the graphics are well dated. The narration is pretty good. If your target audience are kids or carehome residents. Finally, there's a lot of repetition. There's a lot to be said for the sound of silence. 🌟 FUN-FACT, we are looking forward to the next episode 😮😊
Fun! Is Thanks for the input. Best wishes to the current crop of yachties! I'm not sure I understand the product values comment. As for our target audience, it is indeed the 45+ generation and mostly non-yachties. We cannot keep up with the energy it takes to target younger audiences. We spent a lot of time down in that area. I graduated high school in St. Thomas many moons ago. We worked aboard a 123' Palmer Johnson Ketch called Galileo in that area multiple seasons as well. I would like to get back again at some point but that is far down the road. Take care and don't work yourself too hard! Blaine
Geez Louise your props are admidships! Hows she handle? Take that stern section out and youll be back down to 50' 😂. Maybe next time you have to paint itll cut your shipyard time in half 😊
Surprisingly the handling isn't as bad as you would think. I am debating adding a large auxiliary rudder at the stern though. The stern section adds another 1300 gallons of fuel and 750 gallons of water. Definitely don't want to lose that! Blaine
Eveeryone looking at an older boat in general should watch this. All the hull materials have some sort of achilles heel and the older the boat the more likely the issues are to be present. Thanks for watching!
@OnboardTangaroaSeatrial Of course, but Aluminium is so vulnerable to corrosion and stray current or other electrical problems can accelerate the process so much...
For sure. This boat was the second or third boat made from aluminum from this boatbuilder back in the 60's and you can definitely tell that there were design issues that certainly did not help the longevity of the aluminum in places. .
I bet the engines on the boat run smoother without having to push all that weight.You get rid of that bondo.I'm sure the fuel economy has been improved
Glad you are liking the channel! There is indeed a reason we had the older footage. We actually have another channel that started 4 years ago. We did both travel stuff and refit stuff. The problem is that we had a split audience and youtube was having trouble finding the right audience. Because of this we split the channel. This channel is dedicated to refit and the original channel is only travel and exploration. It has definitely helped to split the channel as this channel has already exceeded the subscribers of the old channel and has only been active for 2-3 weeks. I hope that make sense. Take care. Blaine
My face was actually pretty covered. Ski goggles and full mask plus head covered. The stuff that fell on my face was when I took the gear off. I should have brushed off before doing that. So much dust! Thanks for watching. Janis
@OnboardTangaroaSeatrial Heh, that was the boat equivalent of Tammy Faye Bakkers makeup. Seriously, I have to question the thought process behind that. Very few coatings I've ever seen would work properly with that thickness. I'm surprised with that thickness that you didn't have sheets of it dropping off the hull.
For a same sort off job and hull I went to a big offshore company and let them do the job for €5000,- (while they where working, we became friends) and afterwards included painting! 🙂🎉🎊
We plan to have a lot of the interior work done overseas. Definitely unaffordable to have it done here and interior woodwork is our Achilles heel 🤣. Blaine
@ 😂 I always knew and still know a lot of people. After they sandblast the ship they never let me paying for the paint. For the ship I've now for 22 years I've used about 500 Ltr. two component paint! ☹️🙂🎉🎊
Just wait till the motors need to be done, that'll take more time than sandblasting. As well as a lot more $$$$...Enjoy every minute with the great project. look at it as a bonding and positive life time experience. As you probably already do from the sounds of it..
The hull looks amazing for a 50 plus yo boat.I don't know the plate thickness but the alu boat I'm building at the moment has more distortion then yours
We used alodine in certain areas of the hull. They are pretty sticky about that stuff at boatyards as its pretty toxic. It has to be collected and disposed of properly as you know.
One day i would love to do sort of what you two are doing. Find an older trawler (we will be also on a tight budget), shine her up and make her seaworthy. I'm beginning to question that this may be more than we can handle. You two work great together. I'd be curious to know if you would have proceeded with this project knowing what you know now.
You can definitely find various stages of disrepair. We knew we were in for a huge project when we bought this boat. We have talked about it before and we both think we would have bought this boat if we had to do it again. We may have offered a bit less but we are ok with what we paid. It would cost a lot more just to build a hull like this today. We look at how ridiculously priced boats are today for what you get and at the end of the day with this one we will have exactly what we want.
It was 1/4" new from the deck to the chine, 5/16" from the chine to the keel and 3/8" on the keel. The odd spot with corrosion may be 1/32" to 1/16" thinner than that. Blaine
I have seen the laser cleaning videos. I'm not sure how common the service is up here in Vancouver though. Didn't even think to look for someone offering it. Would be interesting to see how the laser would handle close to an inch of filler and paint though.
Yes! Very windy. We actually got hit by a mini waterspout of some sort, and it spun us so fast then heeled us over 25 degrees. Luckily, nothing fell in or off Tangaroa. It was quite a ride, though. B missed out as he was onshore but Izzie and I had fun. J
I think we really would benefit from some sort of timeline in the video. Perhaps some sort of introduction to every video, I have a bit of a hard time to folow the development and progress of the yacht to today. Love the videos thoug.
We are actually doing the videos in order right now but bringing the projects to completion. Would adding dates in the video help? I can def do that and it's a good idea.
In your first video did you not see the huge amount of fairing material?! It was ridiculously thick as you seem to have found out. I saw it immediately and thought okay...Then you ran it without cleaning the bottom, which made me wonder if you cleaned the intakes? The fouled bottom also prevented you from seeing how the engines would perform. There was now way to see if it could hit maximum RPM. You said you could handle the repairs but if one of those is hurt the repair bill will be huge. I don't know if your skills are up to an inframe rebuild or not... Maybe they are? I've had boats wet blasted before and the system was far better/larger than his was. Was insanely loud but it stripped things in an unreal rate.
Oh, we saw the fairing in some places however where it was coming off was not as thick. We were prepared for either way. Discussions were had with a local painter in Wrangell about blasting at that time but it just didn't happen then. You are correct in that we did not clean the intakes before the sea trial. I was not concerned about reaching max rpm at that time, only that the engines ran, could move the boat, had oil pressure, and did not do anything outrageously terrible. There were absolutely no maintenance records on these engines and with the travelling we plan to do an overhaul at the very least was going to happen anyhow. Unfortunately for the blasting our options were very limited. This company was the only one the yard was allowing at the time. We are happy with the results in the end but not sure we would have gone that route if we had to do it again. Thanks for the comment! Blaine
You never know. We aren't really concerned with resale value so much though. We are building the boat for us and the traveling we plan to do. Hopefully we will recoup some money when we finally get too old to keep her but that is not the goal.
Sand blast , yellow cromate primer, the only thing that really sticks to aluminum, (very important, fiber bondo in pitted arias and white pedit paint on top. Black or grey pedit paint to the water line. Antifouling below the water line,if to stay in the water. Otherwise black pedit below requires frequent out and cleaning, and for Gods sake replace the packing seal while you have it out .(. NEVER WHILE IN THE WATER)!!!.
We will not be repainting the topsides. We are also trying out some different non-metallic bottom paints to see if there is one that works better. All shaft seals were done during this haulout as they are the PSS type. I would definitely not attempt those in the water. Thanks for watching!
Thats really cute, a sandblaster complaining about sand in his eyes, that's like a mechanic complaining about grease on their hands,defiantly not an experienced sandblaster.
@@OnboardTangaroaSeatrial I did a few months sandblasting with the Boilermakers years ago when in school. It's no big deal, the helmet keep everything away from yer head. But being inside furnaces and boilers get a bit warm. A bit uncomfortable hanging 30 feet in the air doing the outside , sure teaches you balance
@@OnboardTangaroaSeatrial It's no big deal just hang there and shoot sand till the metal comes clean, very boring but good money, normal blasting is easy, just stand and shoot sand. Doin a boat like yours would have been cake walk. But like anything, it's hard if you don't know what you're doin or lazy.
Turkey is on the list eventually but we do like doing the work ourselves...because then we know it's done right. We are a bit stubborn. The interior will be done in Asia somewhere after we cruise Japan. We leave in 6 months.
If you think wet blsating sucks, then you should really try regular dry sand blasting. It's 3 times worse than wet, and yes, I have done both many times.
I wonder how many hundreds of pounds of epoxy paint and bondo was removed? I imagine you were sanding because the texture was too rough and would have affected performance, but what was the mistake? Too smooth?
I'll spoil it just for you...let's just say I had to replace the whole bootstripe. Too smooth for epoxy to stick Shhh don't ruin it for anyone else. Cheers Janis
@ just curious, the amount dust was incredible. Love watching and looking forward to the experience vicariously through you . Merry Christmas and a Happy Healthy New Years to you all. ❤️
It was pretty crazy. Such an insane amount of clean up that we had to do. Glad we could share the experience with you. Merry Christmas and Happy New Year to you and yours as well!
@OnboardTangaroaSeatrial I watched a time lapse video of a 120' steel trawler yacht being constructed, and I was not impressed with the quality of metal work. The yachts look impressive when finishing, to get to that finish well over an inch of fairing compound was used. I don't care if the hull is steel or aluminum. With proper metal work, there is no need for that much filler. A good way to finish the decks and many other areas of an aluminum boat is with a spray bedliner product. The real spray bedliner is not a diy process as it requires a $10,000+ spray system, but it works amazing. I have a 42' aluminum landing craft that I use around my Alaska property. It was built in the early 90s,and I have owned it since 2009. It was previously owned by the state of Alaska, and I purchased it as a bare hull and immediately began rebuilding it. I converted it to jet drives powered by a pair of 500hp 5.9 12v cummins engines I rebuilt from dodge truck cores. My buddy owns a line x spray bedliner business, so we went to town spraying bedliner. I ended up coating the engine rooms along with the pilot house interior up to the windows and the entire deck and landing gate. 15 years later, and it has held up perfectly. I have loaded and unloaded my rubber tracked excavator many times with zero damage.
We agree completely. I have had a couple of people recommend the bedliner stuff. Im not sure if its the look we are after but its on the list to look into. Very interesting about your Cummins engines. I am assuming that you may have watched our other channel before we split the tech stuff off of it. If not, you are going to be very interested in what we will be posting for video later. Take care. Blaine
@@OnboardTangaroaSeatrial you can get a good second hand unit for $3k to 4k. Probably a better option if your hull would handle it would be UHP water blasting 40k psi pressure washer.
We had a very minimal survey done. We just wanted to ensure the lower portion of the hull was sound. We knew we were going to be repairing or replacing much of the internals. While there was some corrosion none of it was deep enough to be a structural issue.
Unfortunately the aluminum is soft enough that chipper tools and needle guns could mar it pretty good. Not sure how effective it would be. It was truly terrible stuff. Blaine
Holy sh*t I’ve never seen that much fairing used on a boat hull. The original builder must have had 45 gallon drums of bondo. You guys must have gone through quite a few bulk bags of sand, silica sand you could have had the recycled glass sand but that may have left too rough of a finish. I wonder if a needle scaler would have taken off some of that filler. It would have been a little nerve racking to see what was lurking under the surface.
I can't even begin to imagine how much weight we removed. It was nuts. Not sure if a scaler would have worked might have been too soft to be effective.
Actually; it comes as pallets of 1gal steel cans just like house-paint and is mixed with the hardener. Then 4-6 guys working on a scissors-lift board-sand it smooth in unison on the hull. Nasty, dirty, dusty work in a Tyvek suit that I watched, but never partook in....because I can fab/weld. ;)
It's the same story I always hear- they hype up the water sandblasting process as if it's amazing, only for it to turn into a nightmare mess. You'll be finding sand for years. These companies clearly have limited experience; they should have known it would take much longer than just four days.
Thanks for watching! If you want to know more about Tangaroa - check out our website onboardtangaroa.com. See you next week! Same Time Same Place! Cheers Blaine and Janis
I feel your pain... you are not alone and it is nice to see another couple so dedicated to working together on a boat. Take some time to enjoy each other's company. You both deserve it. Cheers from Nova Scotia!
Thanks so much. We actually really enjoy working together on our project...our retirement home. Sometimes it is overwhelming but most times it's like eating an elephant...one piece one project at a time.
As an old aluminium boat builder you need to use an etch primer first as it adheres to the aluminium and then you need a 2 pack paint over that.
Maybe if we remove the teak decks in the future we will paint underneath. The rest will remain bare. Take care.
Blaine
Tangaroa said "Tiaki mai i ahau, maku ano koe e tiaki" If you look after me, I will look after you. The boat looks good, and I agree who ever welded her did a fantastic job.
What a wonderful saying. We may have to mount that in the wheelhouse. Is that OK? She def needed and deserved some love and we are happy to give it to her. Janis
@@OnboardTangaroaSeatrial Don't forget that any tender you have for the boat should be named Punga who was Tangaroa's son. Wishing you all the very best in your endeavours.
Funny you should say that we just purchased a new to us tender about 3 weeks ago and promptly named it Punga! Thanks!
Hey, I just discovered your channel! What a project!!! But such a cool boat!! Can't wait to see the finished product! Cruise around the SJI so we can see!!
Thank you for your reply. You’re a hell of an engineer and good luck to you and your wife on getting her finished. Will be watching your videos. Happy holidays to your family.
He says Thank You. He's sitting right next to me eating dinner. Thanks for watching and we appreciate your support. Cheers. Janis
Always makes me smile to see a Marine Travel-Lift because they're made just north of me in Sturgeon Bay, WI. Also where I used to build aluminum Palmer Johnson Yachts so I know EXACTLY what you're seeing, smelling...and tasting working on that hull. ;)
Funny enough, Janis and I met working on Galileo. She was a 123' Aluminum Palmer Johnson Ketch! I was engineer on that yacht for four years. We loved it. Such a nice yacht. That is one of the main reasons we wanted an aluminum yacht.
Blaine
It is a super yatch. great to see
Thanks. We kinda call her an "Explorer boat" now that she is "naked"
All our customs boats are bare aluminium here in Australia . As son of a marine engineer, hull builder . And master class 5 holder . There going to be more worms in that can that I would take on . Good on you guys .
My dad built and designed all the catamaran ferry’s here in Australia. And drove them until he retired and then pass away 18 months later
The hull has actually been pretty good. Other than that aft deck there are no major issues. That was the only thing we were concerned with. Much of the mechanicals and electricals will be replaced ultimately. Sorry to hear your father passed so soon after retirement. I had a good friend who passed shortly after retirement as well. That is why we are quitting out jobs and going travelling while we still can. Thanks for watching!
come from a commercial fishing family in Australia and we own nothing but bare aluminium boats and is the only way to go, we beach them, launch them from beaches up to 30 foot long, run crab pots and nets up the sides. paint is for rich people with no clue who want to look fancy is all..
We have a 10 foot aluminium dinghy my old man has had since he was 10 years old and lived full time in the ocean behind many of his trawlers etc, sunk 3 times while being towed, and barnacles so thick took me ages to scrape them off. barely even pitted from the salt from corrosion too.
Steel rusts, wood needs to much maintenance and fibreglass can crack in bad weather.
Would own only aluminium and no paint except anti foul on the hull...
We love the bare aluminum look and its so easy to maintain. Definitely happy we did it. I think there are a lot of people who think aluminum just wastes away in seawater.
The Bay Class Border Force units ACV Corio., Hervey, Dame Roma... they were all given a Nyalic overcoat.
Back in the early 90s we were able to tour the Palmer Johnson boatworks in Sturgeon Bay Wisconsin. They were at the finishing stages of a large motoryacht for a unnamed party. They were fairing the hull with buckets of "fairing compound". Bondo! For us, that was not something we had thought of when looking at a beautifully finished hull.
Funny enough, Janis and I met on an aluminum 123' Palmer Johnson ketch and had a repaint done at Orams marine in Aukland, NZ! Definitely some filler there!
Blaine
@@OnboardTangaroaSeatrial Holy CRAP!! 😆I used to WORK THERE before they closed-up! (thanks a LOT Timmur Muhamed/1000 years of combined employee ship-building experience flushed down the toilet🙄) I still have a gallon of leftover & unopened Awl-Grip pink fairing compound in my basement and a ton of aluminum deck-plating scrap from the engine-room. The drink-coaster on my night-stand is a leftover piece of polished marble from a 123' one-off fiberglass yacht that I dug out of the trash and cut into a square (burning up an $80 bandsaw blade in the process🤭). So cool you met on a PJ.
The sport-yachts we built are sleek, beautiful, fast (for their size) and were guaranteed to do 30kts.
Good luck from NE Wisconsin. ✌
Love that raw aluminum look 👍
We love it too. Looks more "battleship" now. Lol.
That is one ambitious project,,,,,best of luck
Thanks! It is indeed ambitious. We will have projects ongoing on her for years to come.
I bet it'll look great when it's finished! I love shiny aluminum!
She will be a bit shinier but we don't mind oxidation either. At least she isn't corroding then.
*Tangaroa* : Canadian for Money Pit!
We could be spending our money on alcohol and strippers...this is more fun
And still cheaper than a house up here.
Hi Bab .n. Blaine we had a Ally 32ft Boat a a friend had the same boat built by same company he painted his boat and we left ours Natural 5 years down line he had those blisters which he had to take all paint off and our boat was still in good nick only problem we had was the dreadful electrolytic which we put a cable right though the whole boat and solved our problem so far so good we had our boat for nearly 15years and the other owner says boat is awesome
Glad to hear that we are not crazy! We are at 3 years bare so far and it seems to be working great!
Hi guys! Nice to have some people tackling such big project! I myself want to start on my classic Van Lent Feadship this summer i will document it on youtube aswell
Awesome. So glad that other people think like we do. Old yachts have personality and are well built. They just need some love...and a sheet load of work. Cheers janis
I wonder how much weight savings from removing all that bondo and paint and leaving it bare aluminum? love the look of bare aluminum btw, great choice!
When the fair a hull Al Steel even GRP it tends to add a considerable amount of Wt ... Something this size you are talking about 100-150 kg of fairing.
Steel boats can be worse still..... Really wt conscious vessels they try to avoid it as much as possible. That means a lot of time on the moulds and mould finish..before laying up.
Looking again it could be even more fairing compound 😬
I can't even begin to imagine the weight reduction. We are very happy with the result though.
I meet once 1 Off build 65 feet aluminum motorboat in Sweden. He left it unpainted , and the boat was absolutely super and looks great !
We love the look and its much easier to maintain.
@@clivestainlesssteelwomble7665 I weigh 100kg, so I'd guess more... hundreds
this was just excellent ... I love the raw aluminum look and am very curious how it ends up looking on this style of boat ... the few shots at the end with the nice stripe looked great
Thanks! We do love the look. It luxury yacht meets battleship.😁
Blaine
It's not body filler it is a fairing compound which is put on most high-end aluminium boats to give a smooth rounded finish then it's painted over with primers and then a good top coat you should have known that when buying i.e. a metal or aluminium boat and what you did to help along was the right thing to do well done its blummin hard work but now that done why don't you paint it yourself you can roller on the paint you will need to put an acid etch paint on first to get the paint to bond onto the metal then away you go anyone can do it it will cost you a bit in paint but saving up is the way to go.
We are glad we did it for sure. We don't plan on painting her again, at least not in the foreseeable future.
Blaine
Yeah that's so necessary that sandblast but you know what you should have done with the naked aluminum part is taking 1400 Grit or wet sandpaper and do circles or you get a circle pattern and it nice and shiny the aluminum up and then clear coat it to 3or 4 coats of clear coat and be nice and bright and shiny
We plan to go further with it but it will be a while. Thanks for watching!
Aluminum is one of the most difficult materials to paint. The problem is OXIDES! Aluminum produces a protective oxide layer within minutes and no paint, including zinc oxide primer will adhere well. What I found out is to strip down to the bare metal. Just before you are ready to paint go back and sand or DRY blast an area that you can paint in one hour. Clean off the area with dry air or dry cloth. Do NOT use acetone, water, alcohol or any other cleaner. Anything will accelerate that oxidation process before you had you a chance to paint should be avoided. Repeat the process all the way around. Never use a wire wheel to final prep for paint. The wire burnished surface is terrible for paint adhesion.
Great advice. That is exactly how we painted our bottom but that video is coming up soon. We also just got a new to us aluminum dinghy and put bottom paint on her. We do use alumaprep though or what is called alodine. Cheers Janis
Use good paint. I always using Sigmacover 280 for the First Layer for Aluminium and Steel. 🙂
Thanks for the suggestion!
After all that, I think I would have tig welded the deeper pitts and ground them down flush, just so there were no thin spots in that quarter inch plate. Wouldn't have cost much more nor taken much time compared to what you spent already. She is a really nice boat though.
That's my plan for the rest of the hull. Lots of little pits to tackle though. I can weld at anchor. I do not currently have a spoolgun and Tig welding them would just take too much time. A spoolgun is on the wish list though! We will definitely spend the time to make her good. Merry Christmas!
Blaine
OK, so I have now seen 3 videos from this series and I seem to be going back and forward in time. That said, every video so far is extremely interesting and I am in awe as to the work you are carrying out - do you know when this vessel will be completed or is it like my boat, an ongoing restoration job.
The timeframe definitely jumps a bit as we have revamped the videos to try and show a complete project. As this ha been ongoing for 4 years now there is some back and forth. This is very much like you describe your boat. I don't feel it will ever be done. There seems to be a never ending list of things to do! Glad you are enjoying the vids.
Blaine
Interesting. I'm planning on building an aluminum sailing boat next summer and will not cover it all that much with paint after watching this video. Thanks for the tip.
Happy if we can help someone prevent this type of damage. It's not that you can't get a good paint job on aluminum. It's just harder to maintain and the prep is even more critical.
@@OnboardTangaroaSeatrial Your the second channel that I've seen talk a little bit about it but you did a way more informative job. The other video I saw just mentioned that the paint doesn't like to stick to aluminum after so many years. That channel is Sailing Life on Jupiter. That's the boat that I want. It has spray foam on the inside that is covered by fiberglass. I'm not sure if that will cause the aluminum on the inside to have problems or not.
I am always a bit leary about covering the aluminum with anything that can absorb moisture. I also think about how much effort it would take to prep an area if I had to weld. Spray foam would not be much fun there.
wow thats a huge job.we know how nice it is when its quiet we have a neighbor who does his projects illegal without permits including deforestation and has been dumping thousands of trucks of dirt nextdoor for years and the noise is sometimes incredible.he has friends who work at the county to protect his illegal dumping my guess is they share the profits for dumping.seems everyday some dumb tractor is running.your lucky its quiet again.boat looks good
The constant noise is definitely grinding. Sorry to hear you are dealing with that on a regular basis.
Blaine
Looks to me like the prep wasn't enough at some point and here you are.
You bet! Prep is everything.
I did the topside of my 32' Marinette. The best way I came up with was a flapdisk 40-60 grit and a hose. With lots of water I could push hard and the disk wouldn't gum up. No dust. A disk would last hours. Maybe 4 4.5 in disks for the topside. The only corrosion was under the bondo and in the bilge under the tar.
I should add that if you've gone this far you should paint it. Sand a bit by hand or the orbital sander, then undercoat. Roller was great, tip with a 2nd roller no bubbles. I don't know why marine paint needs tipping. Forget tipping with the brush. Put a 5 ft handle on the rollers. Use a high density foam roller for tipping. Unfortunately they fall apart after 20 min. Get lots of those.
Thanks for the suggestions! She won't be painted again though. At least not for a very long time.
Sandblasting is the right surface profile for great paint adhesion. Soda blasting would have smoothed out the roughness of the sand blasting.
I had heard the blasting was good for adhesion. We had not thought about soda blasting to smooth it out though. Maybe a future project? Thanks for watching!
that was a big job, its good that you have the positivity (you will need it). however, how exciting that its stripped back, it appears that the hull is in good shape, excellent news. she has nice lines. watching from australia.
Her lines were beautiful, and we were pleasantly surprised. Hopefully, we will get down your way with her within the next 5 or so years. Circumnavigating Australia is on our bucketlist. Cheers Janis
@@OnboardTangaroaSeatrial sounds great. pencil me in for a meet up, and possibly more. i'm near sydney
Right on!
I admire your dedication and stoicism.
We actually have fun doing it. Thank you so much for watching. We appreciate the support. Janis
Loving your videos!!!!
Glad you enjoy the content! Plenty more to come.
I’m wonder what grade aluminum was used for the hull.
According to documentation we received from the Haggin Museum (dedicated to this boat builder) all hull material is 5086-1132 alloy.
Bondo uses talcum for a filler and it absorbs water that freezes and cracks and swells. Get the filler without talcum and uses fiberglass instead for a more permanent fix.
Thanks for the advice! We don't plan to ever put paint back on her though. Much easier going to the places and doing the adventures we plan to do with her bare.
Blaine
Another beautiful part of our magic world. 🙏
Thanks. We do live in an amazing world don't we. Janis
I work in a boat yard and we have 2 of these boats in our yard. They were both extended like this one was. And they both have the same fairing compound problems. Along with fuel tank problems. But I beleive they were both extended by Derektor in ft lauterdale. I have all the paper work from when it was done to the one known as “Garbo” it was done in 1978. They will both eventually be cut up
Fortunately we don't seem to have any fuel tank issues. We have decent access and the ones we have been into look good. If I am not mistaken this extension was done in Mexico. Cheers!
Blaine
That was an crazy amount of fairing compound. Crazy I say.
Wasn't it!!! We can't even imagine how much sanding that took to get her ready for.painting. The blasting guy estimated 8000 hrs!!!! Cheers. Janis
You need a elastomeric coating under the paint system. AMS-S-8802 that will give the hull better protection then just the paint system.
Hopefully we wont be doing any painting on her again. Thanks for the advice though.
Blaine
What a project you have. Just a quick observation. Has the stern of Tangaroa been extended at some time - I would guess around 8 - 10 feet.
It had been extended by 13 feer. Good eye. We have never talked about it on video and we don't know when it was done however we are considering making a video about what is on it for tankage and how it affects the location of the props and how Tangaroa drives. Cheers. Janis
I have no interest in sailing the world because of all the nightmare videos I see on youtube, but you tricked me into subscribing because I want to see how you fix this problem. Well done.
Lol, our plan all along was to trick you 🤣. Welcome aboard!
Blaine
All that hard work has now created masterpiece.😋
She is getting there. It will be nice to do the interior.
@@OnboardTangaroaSeatrialfor sure. Make sure you secure it so it doesn't go flying 😂
Lol, its on the list.
I spent 6 years on USN 'tin cans' destroyers. The USN uses a philosophy of PPR (Preserve, Paint, Repair (if necessary)), so a lot of efforts look REALLY FAMILIAR!
What is difference between the different types of grit (used many, but someone else paidfor it)? Black magic (tungsten carbide), corn cob, sand...
P.S. my first ship (now this comparing is apples to watermellons) we spent FIVE MONTHS IN DRYDOCK! So after 10 days i too can feel your pain...
5 months! No thank you. The paint is off now or at least the majority of it is. Makes maintenance ao much easier. Cheers. Janis
Thank you for your service by the way
What you’re describing in this video is known as crevice corrosion and not electrolysis or galvanic corrosion. It’s caused by oxygen poor areas saturated below the paint.
Dry blasting would have been faster and the media is reusable. Dry blasting also allows for paint to be applied before a thin corrosion layer forms over the aluminum.
You could have also used a softer media to smooth over the rough surface after blasting with sand.
I do call it poultice corrosion which seems to be another name for what you call crevice corrosion. There was also a couple of electrolysis spots on the hull which I showed in the video. They have a completely different look. Unfortunately the shipyard did not allow dry blasting due to the dust production. This guy was the only one they allowed in at the time. As there won't be paint going back on we don't have to worry about the oxide layer reforming. Thanks for the suggestions though. You never know if paint may be a possibility in the future.
Merry Christmas Yacht crew!!!!!!!!!!!!! Big bear hugs from Kenny in Ohio, USA!!!!!!!!!!!!!!!!!!!!!!!!!!!
Merry Christmas Kenny!
Blaine, Janis you guys are the best how interesting. It’s Sunday and I’m watching your videos (hours) instead of my NFL football games. That’s how much you have aroused my interest in your yacht project, guys are awesome. Do you have any videos of the outside or inside of the finished Yacht as of December 2024 today?
Well, if you are from the states we know how important Sunday football is so we are honored 😁! Lol, she is far from finished today but we are trying to figure out how to best do that. The interior is still pretty torn apart as there is still tons of wiring and plumbing to do which goes slowly with full time jobs.
🌟 Guys, you were broadcasted via #messtv onboard a 116-foot super yacht off the coast of St Baths in the Caribbean
Crew Feedback. just watch your product values and the final finish of each broadcast. When watching It feels very 2005ish, and the graphics are well dated. The narration is pretty good. If your target audience are kids or carehome residents. Finally, there's a lot of repetition. There's a lot to be said for the sound of silence.
🌟 FUN-FACT, we are looking forward to the next episode 😮😊
Fun! Is Thanks for the input. Best wishes to the current crop of yachties! I'm not sure I understand the product values comment. As for our target audience, it is indeed the 45+ generation and mostly non-yachties. We cannot keep up with the energy it takes to target younger audiences.
We spent a lot of time down in that area. I graduated high school in St. Thomas many moons ago. We worked aboard a 123' Palmer Johnson Ketch called Galileo in that area multiple seasons as well. I would like to get back again at some point but that is far down the road. Take care and don't work yourself too hard!
Blaine
116' ain't no 'super yacht'.😆 What's your crew compliment? 4-5?? 🤣
I would for sure do a custom vinyl wrap on the boat ..
We have some ideas!
That looks like an awesome boat
Thanks! We love her.
Geez Louise your props are admidships! Hows she handle? Take that stern section out and youll be back down to 50' 😂. Maybe next time you have to paint itll cut your shipyard time in half 😊
Surprisingly the handling isn't as bad as you would think. I am debating adding a large auxiliary rudder at the stern though. The stern section adds another 1300 gallons of fuel and 750 gallons of water. Definitely don't want to lose that!
Blaine
That’s the trouble with paint, it hides a multiple of sins. If you’re keeping the boat, then it’s worth it. Even for peace of mind 👍👍👍
So worth it. Love this boat and love the bare hull look. Thanks for your support. Janis
interprotect 2000e works well on aluminum.
That is indeed what we use anywhere that requires paint, like the bottom. So far it has been great.
Blaine
Everyone looking at buying an older aluminium boat should watch this....
Eveeryone looking at an older boat in general should watch this. All the hull materials have some sort of achilles heel and the older the boat the more likely the issues are to be present. Thanks for watching!
@OnboardTangaroaSeatrial Of course, but Aluminium is so vulnerable to corrosion and stray current or other electrical problems can accelerate the process so much...
For sure. This boat was the second or third boat made from aluminum from this boatbuilder back in the 60's and you can definitely tell that there were design issues that certainly did not help the longevity of the aluminum in places. .
I bet the engines on the boat run smoother without having to push all that weight.You get rid of that bondo.I'm sure the fuel economy has been improved
It certainly doesn't hurt!
Blaine
I'm thoroughly enjoying this series. Curious though, was there a reason that you held these videos for 3 years before releasing them?
Glad you are liking the channel! There is indeed a reason we had the older footage. We actually have another channel that started 4 years ago. We did both travel stuff and refit stuff. The problem is that we had a split audience and youtube was having trouble finding the right audience. Because of this we split the channel. This channel is dedicated to refit and the original channel is only travel and exploration. It has definitely helped to split the channel as this channel has already exceeded the subscribers of the old channel and has only been active for 2-3 weeks. I hope that make sense. Take care.
Blaine
That makes sense. I found you because I started watching InTooDeep. Looking forward to seeing the rest of your videos.
We hope we can keep you interested!
Keep them coming!!!
Shall do. Next week...hydronic heater.
Gotta use more protective gear and reduce contact with nasty debris.
My face was actually pretty covered. Ski goggles and full mask plus head covered. The stuff that fell on my face was when I took the gear off. I should have brushed off before doing that. So much dust! Thanks for watching. Janis
That bondo was INSANE.
Sooo much weight!
That was my thoughts exactly 😳@@OnboardTangaroaSeatrial
They call it Fairing Compound. The entire hull should be covered with it.
We just used "Bondo" as a generic term. The entire hull was definitely covered with it.
Blaine
@OnboardTangaroaSeatrial Heh, that was the boat equivalent of Tammy Faye Bakkers makeup. Seriously, I have to question the thought process behind that. Very few coatings I've ever seen would work properly with that thickness. I'm surprised with that thickness that you didn't have sheets of it dropping off the hull.
For a same sort off job and hull I went to a big offshore company and let them do the job for €5000,- (while they where working, we became friends) and afterwards included painting! 🙂🎉🎊
We plan to have a lot of the interior work done overseas. Definitely unaffordable to have it done here and interior woodwork is our Achilles heel 🤣.
Blaine
@ 😂 I always knew and still know a lot of people. After they sandblast the ship they never let me paying for the paint. For the ship I've now for 22 years I've used about 500 Ltr. two component paint! ☹️🙂🎉🎊
Just wait till the motors need to be done, that'll take more time than sandblasting. As well as a lot more $$$$...Enjoy every minute with the great project. look at it as a bonding and positive life time experience. As you probably already do from the sounds of it..
Yes indeed! We do love the project and enjoy working on her. Many memories have been made from the experience. Thanks for watching!
Wonder what the change to the waterline will be after getting rid of all that Bondo weight...
We are quite a bit higher, but I did change the waterline to account for it. It's coming up in a future video. Promise. Janis
I was a sand-blaster for about a year in the UK, I was shitting sand for another two years.
🤣🤣. Thanks for the laugh!
bare aluminum never rust and looks good
We love the look of her now. More of an Explorer boat then yacht.
So far how much have you spent on to of what you paid for it !!!??? Love the boat
Not exactly sure but plenty! Its all been worth it. Thanks for watching!
The hull looks amazing for a 50 plus yo boat.I don't know the plate thickness but the alu boat I'm building at the moment has more distortion then yours
Not bad eh! We love the curves.
Is the aluminum too old to do an alodine treatment? We use it on aluminum in the aviation industry
We used alodine in certain areas of the hull. They are pretty sticky about that stuff at boatyards as its pretty toxic. It has to be collected and disposed of properly as you know.
Wondering what particular aluminum was used and was this boat stored in salt water.
If I remember correctly it was 5086 aluminum. She has been in salt water since 1969. Thanks for watching!
Removing the paint would make it a lot lighter in the water. 💦
She is now only 80 000 lbs. We also lost quite a bit of weight when we did the repower which you will see soon.
Is it 5086 or 5052 or 6061 hull plate ?
If I remember correctly its 5086.
Blaine
One day i would love to do sort of what you two are doing. Find an older trawler (we will be also on a tight budget), shine her up and make her seaworthy. I'm beginning to question that this may be more than we can handle. You two work great together. I'd be curious to know if you would have proceeded with this project knowing what you know now.
You can definitely find various stages of disrepair. We knew we were in for a huge project when we bought this boat. We have talked about it before and we both think we would have bought this boat if we had to do it again. We may have offered a bit less but we are ok with what we paid. It would cost a lot more just to build a hull like this today. We look at how ridiculously priced boats are today for what you get and at the end of the day with this one we will have exactly what we want.
@@OnboardTangaroaSeatrial Yup, that is a very good way to think of it. Merry Christmas!
Merry Christmas and Happy New Year!
My father purchased a wooden boat. It was rotten. Started to repair it, but he ended up feeding it into the wood burner.
That's sad. He probably had an amazing dream that he had to burn. Wood is hard to maintain which is why we looked high and low for aluminum.
If the hull is 1/4” thick now what was it new?
It was 1/4" new from the deck to the chine, 5/16" from the chine to the keel and 3/8" on the keel. The odd spot with corrosion may be 1/32" to 1/16" thinner than that.
Blaine
I wonder if the product Aluma-Clear would work on this type of application 🤔
Not sure. Will have to look into that. Thanks for watching!
Too late but have you heard of Laser paint removal and spray welding aluminum this would give you the best finish
I have seen the laser cleaning videos. I'm not sure how common the service is up here in Vancouver though. Didn't even think to look for someone offering it. Would be interesting to see how the laser would handle close to an inch of filler and paint though.
Was it windy there yesterday?
Yes! Very windy. We actually got hit by a mini waterspout of some sort, and it spun us so fast then heeled us over 25 degrees. Luckily, nothing fell in or off Tangaroa. It was quite a ride, though. B missed out as he was onshore but Izzie and I had fun. J
Imagine the time and work at the original boat yard putting on an 1" thick layer of filler.!
The blaster guy says he estimated 8000 man hrs which to us is insane. It lasted quite a while though. Gotta give them that. Thanks for watching. Janis
I think we really would benefit from some sort of timeline in the video. Perhaps some sort of introduction to every video, I have a bit of a hard time to folow the development and progress of the yacht to today. Love the videos thoug.
We are actually doing the videos in order right now but bringing the projects to completion. Would adding dates in the video help? I can def do that and it's a good idea.
In your first video did you not see the huge amount of fairing material?! It was ridiculously thick as you seem to have found out. I saw it immediately and thought okay...Then you ran it without cleaning the bottom, which made me wonder if you cleaned the intakes? The fouled bottom also prevented you from seeing how the engines would perform. There was now way to see if it could hit maximum RPM. You said you could handle the repairs but if one of those is hurt the repair bill will be huge. I don't know if your skills are up to an inframe rebuild or not... Maybe they are? I've had boats wet blasted before and the system was far better/larger than his was. Was insanely loud but it stripped things in an unreal rate.
Oh, we saw the fairing in some places however where it was coming off was not as thick. We were prepared for either way. Discussions were had with a local painter in Wrangell about blasting at that time but it just didn't happen then. You are correct in that we did not clean the intakes before the sea trial. I was not concerned about reaching max rpm at that time, only that the engines ran, could move the boat, had oil pressure, and did not do anything outrageously terrible. There were absolutely no maintenance records on these engines and with the travelling we plan to do an overhaul at the very least was going to happen anyhow. Unfortunately for the blasting our options were very limited. This company was the only one the yard was allowing at the time. We are happy with the results in the end but not sure we would have gone that route if we had to do it again. Thanks for the comment!
Blaine
Cheap boat- lot of investments. But at the end value is increase more than money spent on repair. Video proof of real work, and do everything correct
You never know. We aren't really concerned with resale value so much though. We are building the boat for us and the traveling we plan to do. Hopefully we will recoup some money when we finally get too old to keep her but that is not the goal.
Sand blast , yellow cromate primer, the only thing that really sticks to aluminum, (very important, fiber bondo in pitted arias and white pedit paint on top. Black or grey pedit paint to the water line. Antifouling below the water line,if to stay in the water. Otherwise black pedit below requires frequent out and cleaning, and for Gods sake replace the packing seal while you have it out .(. NEVER WHILE IN THE WATER)!!!.
We will not be repainting the topsides. We are also trying out some different non-metallic bottom paints to see if there is one that works better. All shaft seals were done during this haulout as they are the PSS type. I would definitely not attempt those in the water. Thanks for watching!
tts not Bondo. It's fairing.
Sorry...my fault I call all of it bondo. Kinda like calling sailboards windsurfers and snowmobile skidoos.
Certain popular brands become cultural icons which define the medium, like xerox for Photocopy, Coke for cola, Walkman for personal stereo.
Exactly!
ya wonder how much all of that bondo weighed?
Yeah, we wish the scale had worked on the travelift. Cheers Janis
Thats really cute, a sandblaster complaining about sand in his eyes, that's like a mechanic complaining about grease on their hands,defiantly not an experienced sandblaster.
It looked like a pretty crappy job. Felt bad for the poor guy but he said it was good pay ....cheers Janis
@@OnboardTangaroaSeatrial I did a few months sandblasting with the Boilermakers years ago when in school. It's no big deal, the helmet keep everything away from yer head. But being inside furnaces and boilers get a bit warm. A bit uncomfortable hanging 30 feet in the air doing the outside , sure teaches you balance
Definitely does not sound like a lot of fun.
@@OnboardTangaroaSeatrial It's no big deal just hang there and shoot sand till the metal comes clean, very boring but good money, normal blasting is easy, just stand and shoot sand. Doin a boat like yours would have been cake walk. But like anything, it's hard if you don't know what you're doin or lazy.
A blasting cabinet is about as close as I get. A bit of separation works for me 🤣.
Blaine
Seems like the stern has been added to the Boat ?
It has. There was 13' added some time in the 80's. Thanks for watching!
Take the boat to Turkey and have the repairs carried out.
Turkey is on the list eventually but we do like doing the work ourselves...because then we know it's done right. We are a bit stubborn. The interior will be done in Asia somewhere after we cruise Japan. We leave in 6 months.
If you think wet blsating sucks, then you should really try regular dry sand blasting. It's 3 times worse than wet, and yes, I have done both many times.
I feel bad for anyone who has to do that regularly. Not my kind of profession.
Blaine
very interesting effort! i guess u shaved a ton off the boat?
I really wish I knew how much weight was shaved but unfortunately the scales on the travelift were not working so we have no definite number.
Blaine
I wonder how many hundreds of pounds of epoxy paint and bondo was removed? I imagine you were sanding because the texture was too rough and would have affected performance, but what was the mistake? Too smooth?
I'll spoil it just for you...let's just say I had to replace the whole bootstripe. Too smooth for epoxy to stick
Shhh don't ruin it for anyone else. Cheers Janis
Sanding aluminum oxide with aluminum oxide paper
The sanding was for the bondo, not the oxide layer.
They make a wire wheel with diamond chips on it for the alluminum it's a game changer!!!!
Oooooh, going to have to check that out.
Would it have been cheaper if you hired the blasting gear and do the job yourself. 👍👍
Could have paid me enough to do that job. The poor guy had sand caked inside his eyelids. It was horrible. Cheers Janis
Hi Guys
How much weight did the Tangaroa loose after being stripped.
We are not sure. Sadly the scales on the T-Lift were non-functional at the time.
@ just curious, the amount dust was incredible. Love watching and looking forward to the experience vicariously through you .
Merry Christmas and a Happy Healthy New Years to you all. ❤️
It was pretty crazy. Such an insane amount of clean up that we had to do. Glad we could share the experience with you. Merry Christmas and Happy New Year to you and yours as well!
if it ain't fiberglass it ain't mine 😂
Aluminum actually lasts very well. It is also very easy to repair. We don't mind fiberglass either but we did specifically want aluminum.
I wonder how much weight you saved by removing all the fairing compound.
Wish we knew but the scales on the T-Lift were out of commission at the time.

@OnboardTangaroaSeatrial I watched a time lapse video of a 120' steel trawler yacht being constructed, and I was not impressed with the quality of metal work. The yachts look impressive when finishing, to get to that finish well over an inch of fairing compound was used.
I don't care if the hull is steel or aluminum. With proper metal work, there is no need for that much filler.
A good way to finish the decks and many other areas of an aluminum boat is with a spray bedliner product. The real spray bedliner is not a diy process as it requires a $10,000+ spray system, but it works amazing. I have a 42' aluminum landing craft that I use around my Alaska property. It was built in the early 90s,and I have owned it since 2009. It was previously owned by the state of Alaska, and I purchased it as a bare hull and immediately began rebuilding it. I converted it to jet drives powered by a pair of 500hp 5.9 12v cummins engines I rebuilt from dodge truck cores. My buddy owns a line x spray bedliner business, so we went to town spraying bedliner. I ended up coating the engine rooms along with the pilot house interior up to the windows and the entire deck and landing gate. 15 years later, and it has held up perfectly. I have loaded and unloaded my rubber tracked excavator many times with zero damage.
We agree completely. I have had a couple of people recommend the bedliner stuff. Im not sure if its the look we are after but its on the list to look into. Very interesting about your Cummins engines. I am assuming that you may have watched our other channel before we split the tech stuff off of it. If not, you are going to be very interested in what we will be posting for video later. Take care.

I wonder how much a sandblaster unit would have cost you to buy?
We never looked into that. It was a horrible job. Poor Carl and John had sand caked inside their eyelids! Janis
@@OnboardTangaroaSeatrial you can get a good second hand unit for $3k to 4k. Probably a better option if your hull would handle it would be UHP water blasting 40k psi pressure washer.
Good to know for the future. Thanks!

@@jackdburtrying to scrap it? Too much pressure for aluminum ,will cut aluminum.
Lol, well that wouldn't be good.
Could you have used a needle scaler ? No material cost other than air or electricity
The filler was pretty soft so I'm not sure if the scaler would have "chipped" it away. Hopefully we never have to do it again to find out!
I guess you did not have it surveyed ?
We had a very minimal survey done. We just wanted to ensure the lower portion of the hull was sound. We knew we were going to be repairing or replacing much of the internals. While there was some corrosion none of it was deep enough to be a structural issue.
Bring her to the uk i got a polish guy who will paint that for a fraction of your quote 🤣🤣
We may take you up on that 🤣.
In the first hour, I would have jumped in with chipper tools Grinders needle guns everything just to get that stupid Bondo off so it would go faster.
Unfortunately the aluminum is soft enough that chipper tools and needle guns could mar it pretty good. Not sure how effective it would be. It was truly terrible stuff.

Holy sh*t I’ve never seen that much fairing used on a boat hull. The original builder must have had 45 gallon drums of bondo. You guys must have gone through quite a few bulk bags of sand, silica sand you could have had the recycled glass sand but that may have left too rough of a finish. I wonder if a needle scaler would have taken off some of that filler. It would have been a little nerve racking to see what was lurking under the surface.
I can't even begin to imagine how much weight we removed. It was nuts. Not sure if a scaler would have worked might have been too soft to be effective.
Needle scaler destroys aluminium it is only good for steel.
Personally having sandblasted industrial stuff i would have initially used copper slag then glass to finish.😊
Hopefully we never have to do anything like that again.

Actually; it comes as pallets of 1gal steel cans just like house-paint and is mixed with the hardener. Then 4-6 guys working on a scissors-lift board-sand it smooth in unison on the hull. Nasty, dirty, dusty work in a Tyvek suit that I watched, but never partook in....because I can fab/weld. ;)
I truly hope it wasn’t salt water blasted?
No, it was fresh water. I cant imagine there are any blasters who would want to run saltwater through their machines.

It's the same story I always hear- they hype up the water sandblasting process as if it's amazing, only for it to turn into a nightmare mess. You'll be finding sand for years. These companies clearly have limited experience; they should have known it would take much longer than just four days.
We could not agree more!
