Looking amazing. Last year I bout an old fiberglass bass boat knowing it had a soft floor. After getting it home and removing the floor, I found that all the floatation foam was saturated with years of rainwater and all the wood stringers in the hull were rotten. Having watched you guys fiberglass, I felt up to the challenge of gutting this boat and reglassing in new wood. It was quite satisfying. I'm happy to say that with just a bit more sanding, we will be painting next week. Boat work is a pain, but quite rewarding.
Well I like what your doing the fact that you aren't even in the bodyshop business or paint but you still get right to it That being said I've been painting cars for over 20 years and this isn't me criticizing but before you start the filling it is crucial that you feather your edges back until it's smooth that is how you know that it will last the chipped edges that you filled over will eventually crack and in some cases the filler will fall out and I imagine being a boat that Bob's around flexing much more than a car also the painting I wish I could come work with you for a day alone I could probably have you in pretty good shape by the time you finish this big project you will definitely be much better also your going to be spraying enough to actually buy a decent paint gun I recommend Sata it will last you a long time or resale it after
OMG! You guys are unbelievable, been following since the beginning! How good is it gonna be , when you’re done ,kicking back with a few beers and friends !
That's looking really good! If there is one thing this series has done, it is to convince me that I don't want to go through this process. You really have made good progress and put in a lot of work.
@@MJSailing I saw someone else complain about the music. The music was fitting and not too loud. Don't worry about the complaints because you can't please everyone. Enjoy your trip and be safe, wherever you are headed!
Looking great! You're getting better at painting, but one suggestion from someone that's painted cars: Paint guns typically have a two stage trigger, squeeze the trigger a little and the air starts flowing, squeeze more and it starts spraying material. The way to get perfectly smooth, even application (especially on large surfaces where you can't reach the edges) is you start the air flowing early and turn on the paint just before your sweep reaches the edge of the area to be sprayed. When you reach the other side stop the paint but keep the air flowing for a second. The goal is to have even airflow going before and after you spray material so every droplet hits the surface under exactly the same conditions. This stops the initial "sneeze" of material that happens when you bang the trigger all the way on and stops material fouling up the nozzles when you snap the trigger all the way off and the last of the paint has no air to carry it to the surface.
Continues to look better and better each week. So much to do when it’s just you guys doing all the work over an entire workforce working on a boat. Lookin great! Donate for a Dream
@@MJSailing It may take you years, but you are building your home. It just happens to be on the water. Other people may spend years building a home, that is a house.
Mad props to you both, unbelievably good job! It's almost like you can start to see a glimmer of light at the end of the tunnel that's not an oncoming train : )
The fairing and gel coat really make a difference you guys are amazing with the progress you have made a week away won't make a difference besides you guys need a break.
The amount of work required for this project is insane. Much respect to you both. In a factory setting I would be curious how much added work is required building a boat in this method with numerous pieces versus the traditional molding of top and bottom sections then joining them
I scheduled a lot of things in succession just so I could come to see you in Newport, but the hurricane blew my plans out of the water. The best laid plans of mice and men... We will be down in Easton, MD at some point in the near future, and I'd like to reach out and buy you two dinner or something.
Wow! The finish on the joined parts looks really, really good on video. It seems like it was a whole lot of sanding and faring, but the end result shows you did what was needed to get the end result looking as good as it does.
@@MJSailing It can be. I spent 40+ years producing polymers in 40k different colors. Customer were very particular about lot to lot consistency. Many factors affect colors too many to list. I imagine the shop that builds the completed yacht keeps a supply of same lot gel coat for the seam finishes and touch-up. Aging and uv exposure is out of your control. Your work is looking great! You’re right, the gel coat really makes a big difference.
It looks like Matt knows how to use those drywall mud knives pretty well. I have a lot of experience doing drywall and I have to say excellent job. And yes I know it's not drywall but the process of applying a material and making it as smooth as possible is still the same!
My dad has done a lot of drywall in the past (he build 4 of our houses), so this fall when he comes to visit I'm going to have him fair the outer hull of the guest berth and see how he handles it, lol. - Jessica
Wow I remember the kit arriving, what a day. Now you have a boat that looks like a cat, looking awesome well done both oof you. Also just noticed you are from Kent Island and I am from Kent UK small world huh. The belt sander, a friend of mine runs a body shop for cars and uses one of those belt sanders all the time, handy tool. It looks like the sander works for you also, nice job. Thank you for sharing the video, love watching the progress and the gradual creation of what is going to be an amazing craft 😀
Matt you are an absolute superstar for doing such an insanely cool/good job, I would be tempted to get UV gorilla tape in an accenting color, gorilla glue the joints, tape it and and call it done(my bad!). Stuff last for years, then you could re-accent it when needed! Your way is better though!
I look back to your sailing on Elements and think how much better it will be on this new, spacious home. Anybody who thinks this is not hard won is full of stable gravy. I'll hang on, but I can hardly wait to once again wish you fair winds and following seas.
Excellent. After this project just technology, toilet, bidet spray, laundry machine updates from around the world. No more boat building, just enjoy every moment of the hard work put in. And when the next build comes along hire some hands to speed up the process.
When I made the hard top for our Belize43 we added a thick layer of gelcoat on the edges of the perimeter and I hand sanded it with a home made longboard using finer and finer grit util polishing it to the same quality of the boat. Saved a lot compared to the huge work associated with your procedure. Anyhow, you guys are extreamly thorough and I'm looking forward to seeing the interior work commencing.
Goodness this is looking so awesome :) I know I've said it before but seriously don't apologize for sanding. It's part of the process. I've actually learned quite a bit by watching you guys. Also hope you have a lovely trip!
Hutchins makes a straight line sander about 1 foot long and 2 or 3 inches wide. You fill that concave line in with filler and sand it flat with that sander not the 6 or 8 inch orbital and it will be flat ! Professional auto body men have trouble making that flat with an orbital sander and do it all the time .
This was filmed over 3 months. 🤣 To be fair though, it was about 2 days of work in April, 3 days of work in May, and 3 days of work in September. So, still ahead compared to all the work involved for interior fairing!
Seeing how I’ve only laid up glass once and it was a disaster, I do have a question. Won’t all of the seams shift once your in the water? Won’t the boat twist some seeking it’s own buoyant shape. Wouldn’t that cause stress fractures in the seams?
Wow that gel-coat makes a HUGE difference, its amazing! quick question though.. The stern platforms look like they aren't bonded together on the inboard edge. Am I just seeing that wrong? or have I just forgotten the reason?
I know this is an older video (maybe you've adressed this elsewhere) but what is the benefit to using peelply on these seems if you need to sand the area anyway?
To the people who use millimeters, mils is an abbreviation for millimeter, but to those who use inches, it means thousanth of an inch. That is where the confusion is coming from. The same abbreviation is being used to mean different things. I hope that clears it up.
Why is there a rather sizable gap on the sugar scoops? The boat is really looking beautiful. You guys are doing a great job. Can’t wait to see you in the bahamas
We went back and made 25mil depressions where the seams are in the fairing compound. But you're correct, from now on we're using thickened gelcoat at the filler.
@@MJSailing Ahh, mils has a different meaning here in the uk. One mil (millimetre) equals 39 thousandths of an inch so 25 millimetres is quite a thick coat of paint.
So now that its a one piece boat officially I think you guys are only two stages behind Duracell. 😅 So I wonder how many are betting on Duracell to finish first or MJ?
Call me ignorant if you want, I don't mind, but what IS gel-coat? Given Matt had to get out the power tools to remove it, and the impression that gel is really not a good idea for slipping efficiently through water, it isn't gel after it is applied ... So what actually is it?
Gel coat is the shiny smooth outer surface of a GRP (or fibreglass) moulding and is usually applied first in the mould before adding the glass and epoxy resin coats. In this case it is applied to these joints to achieve a universal shiny smooth surface instead of a paint coat. Hope that helps.
Thanks guys for you answers - damned useful! Basically, it is a very hard, very durable, very smooth, waterproof covering to everything made of fibreglass or carbon fibre etc. It seems (to me) to be the equivalent of varnish on wood - perhaps 1 coat of gelcoat = 10 or 20 coats of varnish on wood. After reading these responses I went to Wikipedia and had a look there for more info. Still not sure why it is called "gel" coat. Wikipedia - they "are thermosetting polymers based on epoxy or unsaturated polyester resin chemistry. Gelcoats are modified resins which are applied to moulds in the liquid state. They are cured to form crosslinked polymers and are subsequently backed with thermoset polymer matrix composites which are often mixtures of polyester resin and fiberglass, or epoxy resin which is most commonly used with carbon fibre for higher specific strength."
Woah, you Americans and metric units!!! 13:45 5mm coats x 5 = 25mm is you apparently adding 1 inch of gelcoat to everything you do! Obviously that is wrong ... 5 microns? ie micrometres? making 0.025 mm thickness??
I'm inclined to add "hugs and cuddles" because I I do love you both, love what you do, know you know vastly more than I will ever know about this. I was just amused by this section. I am a genuine, long time admirer of yours (pl)
Looks like I owe you, and all Americans, an apology! "Mil" is one thousandth of an inch! (eh?) My very old brother-in-law- talks in such terms; I ought to have known! He also uses 'thou' for 1/1000 of an inch. So why say 'mil'? A little more investigation shows "mil itself is derived from the Latin for thousandth; millesimus" You clever Latin speaking people! Apologies, MJ and America
Removing the gel using the grout bit. NOT WRONG but waste of time. Get a rotary rasp 1/8th for Dremel or 1/4" raps for router or router like tool or speed burr bits. you can set the depth with a router. as to using them, its about 130% faster then the grout bit on the multi tool. Spraying gelcoat. IF YOU NEED to make it thick use brush able gel and use a CUP GUN. A grav feed gun is for thin finish layers. Its a waste of time spraying many times with a finish gun. Not to mention you must sand between each layer. CUP GUN... Spraying green PVA over the gelcoat. AGAIN NOT WRONG but waste of time and excessive steps. Use a CUP gun and spray the full thickness using brush able gel upto 20-34 mills. Fyi its a "mill gauge" and when gauging you want to wear black gloves. That way you can gauge and touch it to your gloved hand to see the reveal of the gauge results. Again, I'm just a luxury yacht boat builder working out of Fort Lauderdale and am on a reality show my self in yachts. If your going to finish your seams. The best and fastest way to deal with the seams after the fiberglass patching and after all the prep and masking is done. Is to mix your matching gelcoat with cabosil to thicken it. When ready mix a working amount with MEKP and apply to the cracks with a spreader metal or plastic. Immediately follow that with a low volume small tip cup gun to spray waxed gelcoat over the "patch paste, the thickened gelcoat" thickened applied gelcoat. You have only to sand down the seams, and if done right should be a quick blue dye and sand it with 120 and walk up the grits till you can polish the seams. Its VERY fast. Fairing filler under gelcoat always comes back to bite. when enough gel has been buffed away between SUN exposure and buffing. You will end up with patches showing through the glecoat. If using patch paste or FULLY applying thick enough using a cup gun. All gel coat patched areas should last as long as the original MFG gelcoated areas.
How does the gelcoat sand with Cabosil in it? Do you use any other easier to sand fillers for areas that will need a few rounds of filling? How deep of a depression can be filled this way? Great information and help!
@@MJSailingwas thinking of you guys and praying you never hear - your marina has been sold … we have and are standing by for increased rates and hopefully no restrictions about much time we can spend on our boat … always something. Great job as always !! 👏
Luckily we signed a contract until 2025, so even with new owners were okay.... But I'm sure they'd get us on some other charges. Hopefully it works out for you in the end.

You guys look like you're in a 12 step program. One day at a time, one step at a time.
That makes a huge change. What is with the gap between the deck and the hull on the sugar scoops? I thought that would have been bonded by now.
Seeing how I’ve only laid up glass once and it was a disaster, I do have a question. Won’t all of the seams shift once your in the water? Won’t the boat twist some seeking it’s own buoyant shape. Wouldn’t that cause stress fractures in the seams?
How are you going to handle the sugar scoop/cockpit panel gaps?
There's actually extensions that will be going on the steps, so the entire area is going to need new glassing/molds anyway.
@@MJSailing Ah, I just cringe when I see those gaps. BTW, I am a fellow Michigander. Brighton,Ann Arbor, and Marquette.
Wow that gel-coat makes a HUGE difference, its amazing! quick question though.. The stern platforms look like they aren't bonded together on the inboard edge. Am I just seeing that wrong? or have I just forgotten the reason?
We haven't covered that in the videos yet, but there will be extensions eventually going on them - so that area will be getting cut up anyway. 😉
I know this is an older video (maybe you've adressed this elsewhere) but what is the benefit to using peelply on these seems if you need to sand the area anyway?
Sorry, I thought I heard Matt say that he was applying 25 millimeters of gel coat in 5 layers. That is almost a full inch. That can't be right.
Mils not mm.... It should be 5 thousands of an inch a shot
To the people who use millimeters, mils is an abbreviation for millimeter, but to those who use inches, it means thousanth of an inch. That is where the confusion is coming from. The same abbreviation is being used to mean different things. I hope that clears it up.
Why is there a rather sizable gap on the sugar scoops? The boat is really looking beautiful. You guys are doing a great job. Can’t wait to see you in the bahamas
yeah i have been noticing this for a long time a bit concerning
Good work looks good. It's in usually Jess that does the fairing? ;-)
When you go to Yesterdog, do you order the Yesterdog, the Cheddardog, or the Ultradog?
Looking good, how far behind real time is this?
It was filmed last week
Curious about the apparent gap between deck and hull of aft portion of sugar scoop
They haven't been filled yet. We'll do that when we're building the rudder mounts on the stern (transom hung rudders)
How much will your boat weigh when all completed. The dry weight before you load it up with food, clothing, fuel and water?
Around 13000 lbs light ship without extras
@@MJSailing Thank you!
Should fair that seam with gelcoat. By filling it you have left no room for gelcoat and caused extra work finishing.
We went back and made 25mil depressions where the seams are in the fairing compound. But you're correct, from now on we're using thickened gelcoat at the filler.
Well, at least you can make a video for us, and you get fixed
Matt at 13:58 you said 25mm of Gel Coat with 5 x 5 mm spray coats did you mean micrometers ???.
Mils not mm. Sorry for the confusion
Did I hear that correct, 25 millimetres of gelcoat, that an inch thick layer?
25 mils (thousands of an inch).
@@MJSailing Ahh, mils has a different meaning here in the uk. One mil (millimetre) equals 39 thousandths of an inch so 25 millimetres is quite a thick coat of paint.
Hi I’m Matt, sure…I can build you a catamaran. Amazing intellect and ability.
👍
25mm of gelcoat? Or is that a mistake I make in misunderstanding what you said. You spray it on, so what is the layer thickness?
Sorry. It's not my, but mils (thousands of an inch)
Those who use inches use the abbreviation mil to mean thousanth of an inch, whereas metric users use it to mean a millimeter.
So now that its a one piece boat officially I think you guys are only two stages behind Duracell. 😅 So I wonder how many are betting on Duracell to finish first or MJ?

You have only to sand down the seams, and if done right should be a quick blue dye and sand it with 120 and walk up the grits till you can polish the seams. Its VERY fast. Fairing filler under gelcoat always comes back to bite. when enough gel has been buffed away between SUN exposure and buffing. You will end up with patches showing through the glecoat. If using patch paste or FULLY applying thick enough using a cup gun. All gel coat patched areas should last as long as the original MFG gelcoated areas.
How does the gelcoat sand with Cabosil in it? Do you use any other easier to sand fillers for areas that will need a few rounds of filling? How deep of a depression can be filled this way? Great information and help!
25mill, millimeters? That’s 1 inch in backwards stoneage measurements. It’s late I may have heard wrong.
25 mils (thousands of an inch)
25mm are you sure thats ridiculously thick
it SEEMS y'all still got quite a bit of work left..........
At least a year! Probably more.
@@MJSailingwas thinking of you guys and praying you never hear - your marina has been sold … we have and are standing by for increased rates and hopefully no restrictions about much time we can spend on our boat … always something. Great job as always !! 👏
Luckily we signed a contract until 2025, so even with new owners were okay.... But I'm sure they'd get us on some other charges. Hopefully it works out for you in the end.
25mm total? That doesn’t make sense, 5mm per coat? That would be dribbling
It's mils not MM. So thousands of an inch
👍
