One advantage when sanding here in the United States is that where you need to sand every square centimetre we only need to sand every square inch, which is less than half the number of centimetres :-D Nincompoopery aside, my reaction when you removed the masking tape was "Wow... I am so happy for you (and Athena)." She looks awesome!
Hi Mads, being a shipwright, it’s nice to see you doing such a complete and thorough job on “good old Athena” and not trying to cheap out or cut corners. I am enjoying your videos and look forward to them every week.
Good on you!

That coppercoat is gorgeous!
One of the things that you didn't include in your math was the time to apply the anti-fouling. You need to spend time sanding it off and reapplying every spring - a time consuming process. Based on not having to sand and paint the hull for ~15years seems to be worth the cost of the Copper Coat alone. Thank you for another great video Mads :)
I am committed to this channel and see this refit/rebuild completely through. I have way too much time invested to quit anytime soon. Besides, this is a really fun channel to watch.
Obviously, many are in the same boat... #PunIntended
When he runs aground, then what?
Jake Smith if my aunty had balls..........?
That's the famous "sunk cost fallacy" (but I can't stop watching either)
His great attitude during a long DIY project with lots of unknowns is really enjoyable.
Looks great! Don’t forget the rudder!
Mads, I am preparing my Valiant 40, hauled out in S. Africa, for Coppercoat. I just found information that Coppercoat works well on the bronze strut and a fixed bronze prop. It would work on a stainless shaft, if the shaft was first sandblasted. I just prepared and epoxied my strut for the Coppercoat application. I was going to use Propspeed on the strut but from past experience, Propspeed does not last long on my strut, possibly because of the anode mounted there plus grounding wires which are attached to the strut. We will see how well the Coppercoat hold up on the strut. Propspeed has worked for 2 years on the stainless shaft and Kiwi Prop. The Kiwi Prop blades are made of Zytel, a plastic, the hub is 316 stainless, and no antifouling lasted long on any part of the Kiwi Prop. It will be interesting to see what you decide to do to your strut, shaft and prop.
Hi Mads I am not a sailor or a boat builder, but somehow your journey has hit a key with me. Absolutely love what your doing good luck with Athena.
Yeah I am the same as Walking,,I ask myself why the hell I,m watching,but its so entertaining,I,m actually looking forward to mads getting on with the deck...
Hands down, the most satisfying part of this video was the peeling of the painter's tape. So awesome, lol!
Copper Coat appeals to me, a former copper miner and son of a copper miner. It just seems right and it works too. It does look spiffy too!
Congratulations Mads. Without doubt you have just passed a major milestone. Is it just me but all of a sudden everything seems to have speeded up.
Looks pretty dang spiffy Mads!
My original coppercoat was applied into the mold during the buildinstead of gelcoat. This was in 1993 and it was based on polyester resin, not epoxy. My fiberglass hull was laid up using vinylester resin.
In the tropics, the coppercoat only lasted a couple of years, then needed help from regular antifouling. 5 years ago we discovered osmosis and it turned out to be in the coppercoat, not the vinylester hull. After fixing 700 little blisters and waiting two more seasons to see if more would develop (it didn’t, we got them all first time) we used Interprotect 2000 barriercoat and ablative antifouling. I hope the coppercoat has been improved since then ;-)
You are really getting there now! Such fun to follow along.
We had copper coat from new. We have some areas that still foul with the odd barnacle and some wispy green fouling. Especially near the bow where the profile of the boat is vertical at the water line. We still have to scrub/rub it off, twice a season to remove slime and some growth as mentioned. While we appreciate the barrier properties of the product Please dont think that it is a cure all and nothing grows on it our experience in the last 3 years is thats not strictly the case... Sail safe Ant & Cid xx
I think the value of the boat just went up about 500% - what a great job
You're right: Nothing better than a well documented repair history.
No boats go up in value...I've owned various boats for over 40 years.......just sayin'
Gary if boats wouldn't go up considerably in value with the skilled labour someone credible puts in, I would have starved the last three decades. (fun fact: I did not starve but payed quite some of the bills reviving giveaway boats in "hopeless" conditions back to strong sailors.)
It's different to get a borderline derelict boat, pressure wash it and sell it for a profit. Mads bought a fully functioning sailboat, has done in insane amount of repairs and improvements, but he will never recoup what is spent on materials alone, not to mention labor. His boats value isn't going to go up because of that. I have a friend who buys boats that have been neglected and impounded by the marina, gives them a clean up and sells them. Yea, he's making some money, but we're talking about boats that he sells for between $1000 to $1500. Totally different than what Mads has. I've restored 3 sailboats in my life, and never saw what I spent on materials alone when I sold two of them, but I was like Mads. I enjoyed the work and wanted the boats to go sailing. I stand by my statement that boats don't go up in value, no matter what you do.
I didn't refer to derelict or borderline derelict boats but to boats having issues and aren't marketable for the price the seller originally asked for.
My way to find those was looking at "normal" offers of interesting vessels and let the seller my card with an offer he would have laughed loudly about in the beginning of the process.
When the next but one bill of marina costs is due, the nineth haulout was payed for just to show the visible keelgap once more where already eight other potential buyers poked around, and the offers ever so slowly neared regions where mine was bobbing away, the seller would call and ask whether my offer still stood.
I then would go there, do a through survey and reduce the first offer by the estimated materials - pro prices, lower than retail.
Seller has learnt meanwhile how utterly un-marketable his coffer is.
I more than once bought from original seller's heirs, for there's a reason why good boats develop issues and at last were offered just the deciding piece of time too late to get an average market price.
And: asking prices of supraregionally advertised boats usually are waay over the finally payed price in private market.
The fast-selling ones go to friends, clubmates and people who offered three to fife years prior in the typical "if You ever should offer her - call US!" way of showing their appreciation - and for prices way below the "marketvalue", because the seller want his ship go to loving hands and not to a pretentious rich kid.
Hi Mads, Great job again. The best part of the weekend is sunday evening after you lock the kids and wife in the basement and enjoy the new Sail Life video! Sail Life, probably the best RUclips channel in the world!! When do we get to se a day of your life in Obelix. Many of us don't sail and will be wondering where you cook and what you do when you arent on Athena. Good luck and se you on sunday. 26.003 views WOW
Awesome copper coat. well done
Cheers Rory
That tape line - sooooooo sharp! She looks awesome!
I began watching your videos about a year ago, hell bent to buy a boat and sail the Caribbean. Well, you have persuaded me NOT to buy a boat, the amount of maintenance work is crazy, but I have learnt so much about patience and general stick-to - it - ness! Look at how much you have accomplished. We have learnt that the Scandanavian countries are generally superior, is this magnificent work ethic the reason behind it?
Looking spiffy Mads.
Athena is looking fantastic with her new copper coat. You have a way of making every minute of your videos very interesting and a pleasure to watch. Cheers from the UK. 👍
Love the copper coat looks great
My Sunday afternoon revolves around my Sail Life episode. Never miss it.
She’s flipping gorgeous, Mads. BRAVO.
We used coppercoat on our s&s34 this January and I can say that so far it is perfect (but so would any ordinary antifoul). Big additional cost to go to Coppercoat is that you cant have any older antifoul left on the bottom - you have to clean and sand back to barrier coat which is a hell of a lot more work than clean up any loose or chalky antifoul and reapply with a similar style of antifoul.
Not many boats in our marina use coppercoat. I copped a lot of ill-informed criticism from those whose opinions I didnt value. One person whose opinion I do value said that for boats that just sit in a marina the copper coat doesnt seem to work any better than standard antifoul but for boats that cruised the world it seems to work pretty well. These responses may be from people who's livlihoods rely on rich boat owners paying them to antifoul their yachts on an annual basis. It could also be that marinas are places where antifoul resistant weed and marine growth thrive. In the end Im moving my yacht to a swing mooring where the neighbours are friendlier.
We raised our waterline an inch and now have a nice green/gold waterline that doesnt grow weed - Time will tell about the success of coppercoat but I'm encouraged.
Greate job ,Mats! You got some awesome friends to help you. Lot's of fun it seems. I have followed your journey thoughout all your episodes here on youtube, and you have inspired me a lot. I have purchased a RW 32 and there's quite a few issues to take care of on that boat. Your series will help me tremendesly. Thanks Mats! I will , with excitement, follow you, and get more tips I can use. /Per fro Sweden
My boating days are way behind me and what you are doing was beyond me even at my prime... but I have enjoyed the heck out of your videos. Your English, idioms and all, is excellent!
Mads, I have never commented on your channel which I have enjoyed greatly thru the years. I am commenting on a past video where you removed some smell foam from the keel. In this video you removed the barrier layer of the integral keel. To be clear an integral keel sailboat, such as yours has a keel that is part of the molded hull and not a bolt on keel which is popular on production boat due to the fact it supports a number of different depth and performance configurations. Having at least one barrier layer is a requirement of ABYS for integral keel fiberglass sailboats and some boats have two. Our Caliber 40 LRC has two and it is great comfort to have when sailing the shallow waters of the Caribbean. The barrier layer is in the event the keel strikes a hard object and is holed. While the water can get into the keel spaces it cannot flood the boat until the barrier is breached.
A strike or grounding hard enough to hole the keel skin could damage a poorly made barrier so I recommend your do a good job on the installation. You do very good work so I am not concerned with the quality of your installations. I cannot say I am very familiar with your boat so I cannot layout a design however I will make a few suggestions.
1. I would not leave the space simple empty and filled with air or a dry gas. Due to temperature changes the differential pressure between the outside water and the interior of the keel body could lead to failures.
2. You could replace it with closed cell foam or if your boat is not weight sensitive additional ballast material. Either way something that takes up volume. I have even heard of these things filled with oil though I do not recommend that.
The only reason I am commenting is I have not heard you return to this subject lately and don't know if you are planning actions for this area. It certainly does not have to be address while you are in the shed where other project schedules are driving your actions at present.
I have spent many years building ships and enjoy sea going vessel technology. We have a blog SV Kooky Dance if you want to make sure I am not a kook.
Happy Regards

That's gotta be the spiffiest spiffy we have had in a while. What a great stride towards seaworthiness.
WOW Mads, awesome job looks great.
Minions are great, glad you got rid of pinholes, excited about how she will turn out!
It’s very gratifying to see the boat coming along so well!
Don't think we didn't notice that one of those beers had already been removed!
"Somewhat" extensive!!! LOL. No need to qualify, this is definitely an extensive refit. Great job Mads, keep up the good work. I never miss an episode 👌
Nice lines, spiffy.
Your killing it homie!
Enjoyed your video and your attention to detail very much.
Mads a milestone worth celebrating !!
Athena looks crisp and clean. Nice work!
All the work looks beautiful!
Great work Mads!
Great job Mads! Really appreciate and am so envious of the attention to detail you have. Just finished my antifouling this morning - haul out fees here in Sydney are just a little higher at $1052 for a weekend (on a 27ft boat)!
Drinking Game:
Every time Mads says Copper Coat, take a shot.
Or Glorious glorious sanding....hick
Or spiffy.
No thanks. I don’t want to die
Mads, I love the way the copper coat looks and I agree with you pulling off the tape to expose that rigid line is always a great great feeling
Looks pretty sweet Mads, especially when the tape was pulled off and that beautifully clean line appeared!
I copper coated my boats bottom 3 years ago. I left the final sanding far too long. The scotch brite pad wouldn't touch it at all. Neither would 240 paper. I ended up using 80 grit because... .. . that epoxy is hard like diamonds! However, it works fabulously. I moor my boat in a river which is 'brackish' so slime and weed will grow and barnacles / mussels will grown on the slime but it's easy to fix with a scraper - comes right off.
I think I was smiling as big as you were when the masking tape was coming off! Well done as usual, great videos.
Phew, well that is one of the main problem areas on Athena, just about all wrapped up. Well done Mads and to the team of minions etc who worked on this. I seem to recall that the copper coat is similar to what the guys on Sailing Uma used on their boat. It sure sounds like a good investment in the long run. 👍
Athena's bottom is looking SHARP!!
Excellent! Mads, was watching on Luckyfish gets Away, his new CopperCoat went from Capetown to Barbados with no growth except some small anemones or barnacles, which starved and wiped off in a week or so at Anchor. I was Convinced. AND Impressed. Oh, and Thanks Much for giving me a reason to Look Forward to Sundays.
its been so long drying out the hull I never thought this day would come.
Splendid job Mads. Athena is looking magnificent
Beautiful and different !!
Athena is really looking spiffy. Great video as always. Keep up the good work.
That copper coat looks fantastic!!! Goof Jody to you and the minions!
Hi Mads. Thanks for mention the differences between the two antifouling types. I really like your videos and always take info from you for my little boat projekts. Grüße aus Hamburg!
In past videos I clearly heard him saying "Copper coat". Reading the comments about people mishearing it as 'cover coat' while still watching the video now has me consistently hearing cover coat... Damn you language, perception, and power of suggestion...
I’m two years in with Coppercoat in New England and on last haul out I had NO growth on my hull! This was the best investment I have made on my Hunter 28.5. You did a great job applying it!!!
Mads love the channel been binge watching for a couple weeks. just a helpful hint, get yourself some disposable stir attachments for your drill they are so much easier.
Wow, with the cover coat on, Athena is really starting to look beautiful. I now am getting an idea on yet hull lines. She is going to be gorgeous when you're done.
Copper coat looks wonderful and you're doing a great job
Man, it looks so good!
Wow very impressive. Good on you
Hi Mads,
Back in 1992 I applied 6 layers of Coppercoat. Very expensive! It worked great for 4 seasons. Then suddenly a quite severe attack from barnacles was observed. After reactivation another 2 seasons went on without severe fouling, though decreased efficiency against algae was observed. No problem for a high pressure washer though. Then tried new reactivation the following season without significant effect. Since then I'm back In app. antifouling ( Hempel Mille extra) yearly with good results. The boat was always on the hard during winter time. I really hope you'll fare better! However, 10 - 15 or even 20 - 25 years of constant seawater exposure with just light scrubbing and without lift out for reactivation seems rather optimistic in my view. Time will show ;-)
Good luck!
Bo Jensen i agree. No way will this be a 10 year fix let alone 25. I dont have copper coat but at 1,800 usd its a bargain. I pay 400.00 a year for bottom paint that lasts 8 months and its 850.00 to haul out.
If copper coat would sell me copper coat for that same 1,800 i would give it a go for sure.
But here in thailand its 10,000 for copper coat . Just the product
I agree, more than 10 years seems optimistic. At least you got 6 years out of yours. Also if you spend all your time in colder water, growth and paint deterioation will be less.
That hull turned out just gorgeous!
Hi Mads, from experience I have found when patching copper coat use a scale to get the right ratio for small batches. So the normal ratio is 1:1 1ltr mixed epoxy to 1kg copper, therefore 250ml of mixed epoxy needs 250g of copper and so on. By the way I have followed the Refit from the start and always look forward to Sunday's.
WoW again ! Really looks Good .
Looks beautiful.
Forgive my ignorance I am by no means a boat guy I just love this channel. All this time I thought it was a "cover" coat. And now I learn its a "copper" coat. My mind is blown lol.
Yeah, it is the Danish language shining through there.
@@kimfucku8074 It makes perfect sense to me now though. Im not really sure why I like this channel but I've watching for a long time lol. Sundays are comlete when I get that notification
Feel the same. Hope he finds more to sand and coat!
Oh, Boy! It's really looking like a boat again. The light at the end of the tunnel must be getting pretty bright.
you've done a lovely job of the hull, and great to have help of course
Looks great. Now the outsides pretty much 100% restored. Good job you inspire me!!!
Wow, Athena's hull is looking amazing! You are doing a fantastic job on Athena Mads, keep it up mate.
You have the best friends!
Not one to make commitments much but just want to say your doing an amazing job, looks awesome and keep up the great work.
Great job Mads et. al. :) Athena looks great with her new copper coat. Cheers from PEI Canada, Bryan
Great job!! Looks AWESOME!!
Looking DAAAANG SPIFFY there Mads!!!☺️
What a good channel!
spiffy X 1000. Well done friend
She's coming along! Quite a beauty.
Love the videos Mads. Great info and explaining why you choose things. Is it wrong I was waiting for you to say glorious glorious sanding? You are so upbeat about the some of the tedious time consuming and some would say soul draining chores, one just has to smile with you.
fine job there Skipper
M A G N I F I C E N T !
Great job Mads. I'm going to call it SUPER Spiffy.
Looks great nice job 👍👍👍
External ballast!! Good idea! Glorious, glorious spiffy! I never liked bootstripes anyway.
Beautiful job !!!
I asked White Spot if she spent more on "refit" than a much newer boat. She said a much newer boat would definitely have been less expensive. But she's like you in that respect.
So are a lot of people. My boat is older too, but the work I do on her creates a stronger bond. She seems like another human or a pet, a solid part of our family.
CK H Ah,but he now knows about and has rectified all the original building defects and corner-cutting.
If I owned the same make/model as Athena,I would be concerned after seeing what was found.
I have no great confidence that newer boats would be any better !
So,for me ,the extra perceived cost is worth it.
That's exactly why I'd rather buy an older boat for less then go through it with a fine tooth comb. I hear more and more how newer boats aren't built with as much strength. I worry about keels that come off of newer boats. Maybe steel is the way to go.
*Lydia Johnson* Doing it Yourself can be the way to go when You have an attitude like Mads (or SV Seeker's Doug, for that matter), while I as a boatbuilder with over 30 years of practice under his belt, I have to warn You that it is an awful lot of hard physical work, which is quadrupling without firstclass professional tooling.
Just think about the overhead work You saw here: nothing a normal middleaged indoor pencilpusher usually does, so it is an extreme workout, for nobody in its right mind would do such a work voluntary.
That is the reason why professional osmosis treatment is so extremely expensive, and why osmosis so often is a death sentence to elder GRP boats in case of a thorough assessment and realistic cost estimate ....
To get an osmosis-coffer and fix it Yourself like Mads does it can be a way towards a large boat for a dinghi price though - as far as You do not count Your time and effort besides the money put in.
You are right about all of it. In my case, I don't need to do an osmosis treatment. I am finding and filling all the many holes above deck, including removing the stanchions and resetting them. I may have to remove and reset the toe rails as well. But, I enjoy learning this work. The more skills I can learn in life the better. I crewed on a tall ship a few years ago, which was steel--talk about a lot of work. We had to remove the rust sheen, on the entire boat, after EVERY passage. Grrr!
Excellent tutorial! ...Waves
She looks AMMMAAZZING! Well done!
It looks fantastic!!
Looking pretty dang spiffy! Good to have friends. :D Good work Mads & Minions.
Fabulous, great job!
Just gorgeous! I love copper coat and the effect that gives once you see it in person it is just amazing you did a wonderful job like usual you got some great friends.
I would recommend you to put antifouling (hard antifouling) on top of the copper coat. At least one coat. The marine life will most probably hold on to the copper, antifouling is better in doing so and if you don't raise the boat every winter it will protect the surface even more. You will have to scrub the copper coat with hard stuff to get rid of marine life, so just a recommendation to finish up with real good working antifouling
Nice spiffy copperhead ... awesome job done, on to the next...
Excellent job and info Mads. Don't forget to save enough for the rudder - by the way - haven't seen or heard about the rudder in a very long time!
The hull looks better than spiffy! Amazing difference.
