When you’re using that thickened epoxy… make sure to paint the surfaces with “unthickened” epoxy right before. The unthickened will absorb into the substrate and allow a much better bond for the thickened epoxy if you apply the thickened immediately following and before the unthickened cures :-). Great work! Keep the videos coming. You’re making great progress!! Enjoying the vids!

Great work, thank you for your nice videos.

Mark build a bench from scrap pallets and whatever you can find. Working at the right height and in the shade will make the work way easier, scrabbling around on the ground soon gets demoralising. Looking grand keep going.👍

Looked down the comments in hope of finding that someone had already said this ... that scene from 9:20 where you are exhausted looks to me like you have discovered a lot of what Amsterdam is famous for - lager etc Lovely to see that chap introduce himself at about 17 mins - though lots of people said 'hello' - marvellous!

I like it that “Granny” is donating weekly 😂

There is something very satisfying having a cup of coffee Saturday morning (NZ time) and watching Mark work. I feel I have done a days work too and can now relax for the rest of the day, LOL. The guys below are spot on, thin epoxy first it will seal much better.

Agreed, seal the holes below the waterline, unless you need cooling of some sort..

Wonderful job. It's always good to do your best, that way it won't come back and bite you later. Love that music.

Think I would use a plastic bag with corner off to inject filler into cavities to ensure whole space is filled.

As a boatbuilder myself, a little tip! Applying epoxy, or polyester resin, is so much easier with a foam roller than using a paintbrush! You can often consolidate the epoxy at the same time as applying the epoxy. I love your videos, and keep up the great work.

A couple sets of saw horses will make your hard day a little easier. And hopefully keep you off your hands and knees. Your doing a great job love your youtubes

Congrats, that is a great looking 4JH. We were the Yanmar dealer in Cadiz. We re-engined quite a few boats from Perkins to Yanmar. Never had a disappointed customer. Too bad you can’t use the gearbox, hope you get top dollar for it.

THE RUDDERS LOOK GOOD... and the repair in the well for the rudder came out good ... 😊😊😊

Thanks!can't wait for the end product.

I really like the changes you've made, video production and narration

Best background music of any sailing channel

As always,,,soo freaking proud of you Mark! In My humble opinion & as a result of your very tight time line is, for the soo many generous offers of help,,,,,to be specific, focussed & productive! ,,,& before you know it,,,it'll be splash time - yehhhhhhh👏⛵️👏 Love, as always,,🌈🌻Momma🌻🌈 i hope that all made sense!!!🫢

I'll admit I was one to sit there and say ur crazy for buying that boat. But I tell you what I love watching your boat repair videos. Keep up the good work man. Hello from South Florida USA

Jaz goes well with the ever growing facial hair! Good solid progress occurring. I thought you were mad with your choice of vessel but I have a growing feeling that you are going to make me eat my words. Go well!

Rhubard and custard guns, Mark!!! 😂 Keep up the great work. This is fantastic progress, videos are super

Very fulfilling work - hold steady, man, hold steady. She'll get there, and then Yee Haw.

Nothing dodgy! This is your dream boat, do they best job possible!

When applying glass, I find it a lot easier to wet the glass out first then apply it - especially with difficult to access areas. Also same for taping. When going round a radius such as the corner of the rudders, cut wedges/lines out/in to allow better adaption and finish. And when dispensing resin/catalyst by pump, keep the containers vertical!! Looking good and taking shape nicely!

Your content is very important for my week

Amazing progress! Great Job.

Its great youre still in contact with Hanneka as she is a wealth of information. She can steer you in the right direction in creating your engine boxes and might even have plans.

Some good comments, especially putting a plastic bag over and smoothing it down, saves work later. Also trim before it has gone hard. My big concern is that the ply you are fully encapsulating has dried out sufficiently. Epoxy is great for keeping water out….similarly it keeps it in! I have a cheap moisture meter to check. Ok it is not particularly accurate, but does give a good indication.

Welldone Mark, keep at it 🤙

I really like when you show your visitors. The sailing community is so awesome. And that yard seems wonderful.

Always finish a glass job with a layer of peel ply as it helps get a good finish and avoids a lot of sanding between coats. RV

AHOY from Sweden ! Nice jazz. Very good work on the rudders. You are doing all I would do. Extending the glassing would be pointless. Sanding off glass is best restricted, in favour of adding filler to fair the edge. You are competently finishing a great job done by the original builder. Well done Mark !

Mark , make sure when purchasing fibreglass that it comes on a roll and not folded as folding breaks the glass fibres !

When digging out the wet be sure to allow a good dry. Filling over wet May be an issue

Looking good, lot's of progress, keep moving forward one step at a time and before long, the list of accomplishments will be long. Loving the Jazz!

Oh oh oh. I can't wait for the next enthralling episode. ❤❤❤

I thought you were drinking West system for a second, was going to say, Mark…it’s not THAT bad!

Slow but sure,your winning.don’t forget to have a day off,it focuses your mind.keep it real 😊

Your film making skills have increased as much as your boat repair skills.

Crackin job brother!! 💙 I spent a year rebuilding and modernizing an old sail boat. Been a live aboard for 8-9 months now, but I'm only just getting over the trauma that it caused me 🤪

Yeah, nice jazz too!

If I might share a tip with respect to spreading the filler and forcing it into the cracks: Further to the wet-out point raised above, I have found that using a flexible metal "decorator's knife" - or a plastic spatula for that matter - makes it easier to smooth the thickened epoxy and force it in - you want something with as little surface friction as possible (it's the same deal for plastering: please don't ask me how I found this out!) :D Good work fella.

Keep up the great work. I like the style and layout of your videos. Great job from Canada. Cheers.

You can try stretch film wrap to wrap fiberglass as somekinde of pressing material when you use epoxy. Then you will get nice and smooth surface. I saw this trick on a guy's channel, when he using forms to make things with fiberglass and carbon fiber.

Everyone's an expert on youshite. Keep plodding on my friend. Your doing a grand job 👍.

To save heaps of sanding I’ve taken to laying out the “cut to size” glass mat on a flat board with a film of glad wrap on it. Then wetting it out with epoxy is a breeze and you can pick the glad wrap and saturated mat up as one and put it in place “sticky” side down. A bit of smoothing with a roller or scraper and leave to cure. Once cured, the glad wrap peels off easily for better finish and a lot less mess.😁Cheers& Beers from Down Under🍻

Backing tune really swings!!!!

good on you. protect the leading edge, the other will keep you up but the leading edge takes the most abuse. good on you!

Nah mate you've gone down the sides far enough. Doing great job so far. Also comparing what I see now compared to minke you've gained a lot of experience and skill. Keep it up mate.

reminds of so many days in the yard!!!!

You are doing great...im excited for you!!

Yard work is hard work. Always feel the time pressure.

You need to feather the edges of the ply (scarf) then butter all edges with thickened epoxy.. having wetted them first.

I liked the jazz background...good work as usual!

Just keep plugging away, you will get it done. I can't wait to see you get her on the water and in the wind 😊

Please wear a mask when mixing the powdered epoxy filler so you don’t give yourself silicosis or something nasty. Love the videos, have been watching for years. Keep up the awesome work.

Looking good so far. Lets get this man to 100K!

Try and organise a few work parties from groups who want to help. Give them specific jobs to your needs to free you up to solve other issues in the time you have. You'll get there.

The music choices never disappoint

Yes, great idea to seal up the boat. Best of luck. Enjoying the channel. Tks for sharing.

Mark she's looking better and better every time I get to watch your videos keep app the wonderful work blessings to you and yours coming at you from the hills of Southern Oregon

I've done a lot of boatwork, grinding, glassing, and sanding. You're doing a great job. Stay stocked up on coffee and you'll be sailing away soon enough. Cheers!

It is the best job in the world especially when it’s all done and you can stand back and admire your handy-work when she is all painted up, rigged and ready for sea miles. Keep the faith, the reward is coming! SkipRay, Kerry the Kingdom.

You Are a huge inspiration to me! Just bought my second sailboat, thanks for all the videos.

Looking good mark. Keep hydrated and crack on.

Stay positive and keep going 🎉

Great Music 🎶 and jobs well done on Mahi ❤ Remember the words “pretty good” when the Filipina 👯 👯‍♀️ twins 👯‍♂️ are sailing ⛵️ around the world 🌍 with you ❤

Brilliant Mark!

This video is so relatable. I am in the process of starting to renovate my parents house......Holy Shit is the mental total exhausting!!!!!!! Not to mention the physical side of it all

I find a dremel tool is crucial for opening up cracks in the glass, so you can fill them easily. $100.00. Million uses on a boat...

for fiberglass itchy blow up a balloon rub it in your hair and it will pick up all the glass that makes you itchy hope this help it always worked for me back in the day....oh and for filler you can just use baby powder it works just as good for filling and a lot cheaper and dont let the fiberglass matting get wet with water or moisture.... as I see it your doing a very good job keep up the great work

Geeeeeeeeetings from HAMBURG - MAINPORT - HARBOUR - CRUISE - SHIPPERS !!! 🎉

Rhubarb and custard guns 😂 You're an absolute legend mate

Did you know there are pressure-washer noses which suck in sand into the water making them some sort of sand blaster? They are probably rentable, but the karcher ones cost around 80 bucks. The sand has to be pretty fine. There are special kinds of sand, but I did it with just very fine one and it worked.

Those rudders came up a treat,

The boat has come a long way! We were supposed to fly today to San Francisco to buy a crappy sailboat to fix up but the flight got canceled so now we are watching you...

Exciting to see you making great progress

HAPPY EXHAUSTION FROM A JOB WELL DONE IS A GOOD THING! gREAT joB, KEEP GOING!

Wow, call the upload pretty quick this time 😁👍🏾. I just have to say, that I really love the music that you picked for your montages. I'm into jazz, and many friends say that they don't like jazz. But I always tell them that there's a jazz for everyone, and they probably hear it all the time throughout their day and don't even notice it. On another note, being a contractor by trade, I always like seeing the solutions that you come up with for your projects. It reminds me of when I wanted to turn my hobby of making things into a full career and had to work with whatever I could scrounge up, or was given. Those experiences really make for a more well-rounded maker. And when some people that always go by the book are stumped with a challenge, it helps you to think outside the box and creatively to come up with the solution. Working with what you've got is nothing to be ashamed of, as a matter of fact, producing a quality product out of what you've got is actually something to be mighty proud of. Even though I'm sure you love it, many times it's frustrating to live the way you do, and to make a living the way that you do, but just Keep up the good work man, and it'll all come together.

Congratulations! You are starting to get the old gruff sea dog look about yourself ;) Great video!

Your doing great. I look forward to your videos every Friday.

Thumbs up 👍

Nice work Mark you’ve been a busy boy. Very soon you will run out of jobs todo. 😂 Just imagine it. 😊

Hi Mark, You’re doing so well in getting Mahi back to life and I admire your good craftsmanship in fixing the problems you meet with this catamaran. What i admire the most is that you have seen very well that this boat can be saved for a second life with not too much effort. I therefore only wish you lots of success with the rest of the refit of this catamaran.

You're doing a bang up job there.

Mark, for small areas of epoxy filling you will achieve a stronger and smoother bond if you seal the surface of the repair with plastic film or electrical repair tape while it cures.

We absolutely love watching you sand and fibreglass your Mahi instead of cleaning her!😂

Looking good Mark. Opposite here in New Zealand Winter brrrrr cold. Mahi's going well.

@marc, @ 5:26 , i wouldnt want to repair the 'scratched away and picked at' edge of my rudder. Id like a 6" half-moon shaped divet, somewhat round and smooth, very consistent, like youd achieve with a grinder . this is a great example of what im talking about. the amount of time, energy, and built-back-stronger-than-every efficiency you can achieve will make you , happier, more confident, enthused, and way faster than trying not to take too much out, being more complicated and less invasive, etc. the only way id want to use that microballon epoxy batch in the edge of my rudder like that, would be vacuum bagged.

Great work, man. One step at a time, mate, you are getting there. Thanks for sharing.

I love your editing and approach to videos, esp the part where you give updates and show all the supporters. Most youtubers just throw them at the end and people tend to just click away. This format really gives more thanks to all the supporters. Keen to see how this build progresses. Cheers from Belgium.

Thank you for the video señor!!!❤😊

Tip for you: Hey mate! Great work you have done, I love to follow along as I just have purchased my boat - speedboat 😊 A tip for when you’re sanding - you don’t need to remove ALL the old paint. The purpose of sanding it to level the surface and “rough” it, so the new layer will stick😉 Paint on cars and boats are measured in layers and depth, so if you can keep some of the good “old” paint, what would actually be good. The surface should just feel smooth without chirps and craters😊 Also I saw someone else mention it, but prime before you paint. Even use some paint adhesive - will work much greater 👍🏼 Keep up the great work!

That's the way mark..! Stay determined.. Focused.. and happy in your work.. 🥴😂😂DON'T KILL YOURSELF take each day as it comes but afford yourself time off.. Break the routine if you have too.. Make sure you have a rest each day and get some scoff down ya mate.. Fuel the body 😋 and a beer too ( AFTER THE EVENT) 🍻.. It all looks tedious work PREP BEING THE KEY but what I can see its looking good .. till your next vlog 🙏👍👏👏👏💯🇬🇧 ps beans on toast with brown sauce..! Pilchards on toast with brown sauce..!! Spam with fried egg on toast with red sauce.!!! Salt and copious amounts of black pepper quick foods to lift ya SPIRIT MY FRIEND 👍

Hi Mark, one thing I missed you doing was going over all the added fibreglass with a metal roller to get out all the air bubbles that get trapped underneath, just putting more epoxy on with a brush doesn't do it, also overlaps will be smoother and won't need so much sanding for a good finish. You're welcome 😉. Good idea to finish the hulls first, the rest if need be, done in the water. Crack on young man 🤗

Good music, great work.

Cue The camera angle when the dude came for a conversation and spoke to you under the rudder-perfection in non planning 😊

Lol glad to see I'm not the only one people flock to right after mixing something time sensitive

This KZfaq channel is a great example of what can be accomplished. He bought a boat that had a lot of problems that he did not have the skills to repair or the money to buy the materials to make the repairs. But with persistence he acquired those skills he needed and he acquired the materials he needed. If you want to accomplish something in your life, intelligence is important, and a good work ethic is important, but nothing equals persistence in importance. Persistence will break down every barrier.

Keep up the good work, methodical approach will win the day.

Mate I've been watching you for along time good job. My dad has a heavenly twin 26 in South end you've given me the inspiration to work on her and get her sea worthy. You are an inspiration and if you ever need a deck hand please let me know. CALLUM
