The music is a bit brutal in this one at times. It’s not always easy to find decent copyright free music. I was going for 70s vibe in this one 😂 hope you enjoy it. Thanks for watching!! ✊

LMAO! "It's going to rain today. I can't wait." Yep that'll be the test. Thanks. Got a good laugh out of that.

Greet work! as a naval architect i would recommend putting a few screws into the windows. If you ever hit a big storm those are the first to go. especially salt water will weaken those 3M tapes over time.

You could use wall mirror hangers and not drill the plastic and chance cracking the ploy. Shorter screws n a dab of epoxy.

Well. 3 things. 1st: Those windows will never survive uv exposure with two sided tape. You will lose windows in a stormy sail. 2: Being lazy here means you will regret not having windows you can open for ventilation when it is hot. 3: If you don't build a day shelter/cockpit on the beams to the rear, you will regret not having fun, livable space to hang out with visitors. Take this advice from an old man.

Mark... those windows will never last the way you/ve attached them to the boat. Maybe a frame - surround would help. But double-sided tape and a bead of caulk just won't be strong enough to hold over time and weather.

I KNEW IT! as soon as he said he had a sketchy way to attach the windows my first thought was VHB tape

Captain you really need to get some screws in those windows!

From a dutch boatnut living in the Canadian mountains, Don't worry about the Music! worry about the the Windows leaking !!! I would also agree with adding some screws and making your outside caulking edge wider and more sloped! then Also do the Inside to give it more strength and to keep the gunk out of that little channel you have there now, (it will fill up with dirt and such in no time before you'll get it in the water!) Other then that keep up the good work and keep smiling!!!! Ed

The hardwood strip along the gunnels is called a “rubbing strake”

Those windows will give you most certainly something to think about when you are behind the rudder, with some heavy seas, howling winds and breaching waves. If not now then after a couple of years when everything aged. You are basically relying on tape adhered to a thin layer of paint. Now that is brutal 😃

Mark looking good please make more episodes I am a poor pensioner getting addicted to your boat, you are doing great .

Mark..you can buy ready made boat windows from £45 each 💰🙏...... you'll need stronger secure windows with ventilation if your going to travel seas, oceans to hot climates. You'll need opening windows 🥵🙏

I would put a few screws in those windows as well to be honest.

Can't wait to see how Windows holdup long term but like it

I’d buy some bolts with a rubber seal attached and go around them windows 🙏 better be safe than sorry, but it’s a great idea and they look great.

I would put 4 screws in on each conner, just incase a window falls out in the sea and than you got a hole that could sink your boat when the waves get big. Better to be safe than risk a window falling into the sea and lesving you with a potential life threatening problem.

"Bashing Strip" = "Rub Rail" often made of rubber, chrome, etc..., as well.

Doing well. I like the yellow on white. 👍👍

Am sure you know that the windows need stronger fittings Mark...Salt water and heat will break the seal quite quickly, if you are planning on Sailing Oceans, you will need Commercial Grade ,the windows, are excellent ,but good rubber and many bolts are excellent.

Rub Rail was the words you were searching for lol. Love the vids Mark!!!

Cool, with these yellow and blue colour scheme you can easily ask for IKEA to fund you 👍

Hell yeah! It's so enjoyable to see this old girl get a second life while keeping her soul

Mark, I have used that tape for years, I love it BUT, I used it to place my daughter's 8" each name letters on her bedroom wall, 4 of the 7 have stayed up for 5 years, 2 have been replaced twice and 2 have been replaced more, it's random, and summer when they fall off, yet no sun gets in her room, so pot luck on that, I would recommend doing something to secure your windows, that's a big hole should they fail and fail they will, you just don't want that to be in a storm at sea when they fall off!!

I've been in the plastic industry for 42 years, we did hundreds of boat's using double sided adhesive, polycarbonate is unbreakable however it will deteriorate in time , but never had a complaint or failure using this method 👍👍👍

Rubbing strakes is the term that you are looking for. I also agree about the fixings on the windows but I would add that drilling oversized holes, sealing and bolting through is the way to go. Slightly worried about the lack of ventilation without opening ports. A great project but the proof will be in the sailing!

The windows look good. Somme would say only use brose port light-hole. I say do what the feck you want its your boat. 2x👍

Mark,,,you really are an incredible human being💙,,,& Sylvia, what a humble superstar👏👏👏 See you soon & as always, Soo freakin' proud,,Love 🌈🌻 Momma🌻🌈

Looking Good!👍

Looking good once again , my gut feeling is that you should have a few screws holding those windows on as well 😃🍻

I hope the window seal holds up, but Andy is a cold-weather, fresthwater, Canadian boater, not a tropical sailor. I would've probably gone with old school butyl tape around the perimeter, then through bolted them and capped the bolts on the inside with "acorn nuts"(US term). That way they can be removed with ease and/or tightened as needed to eliminate leaks. A lot more like a bolt-on porthole, rather than an inset version that causes the rot you had to deal with. "Streamline" looks cool, but is mostly a PITA to repair/replace. Cheers from FL!

As soon as I saw the tape I thought No No No Way! There WILL be a wave trying to rip ur windows off.

Looking at the comments about the window adhesion. I agree, two things, silicone allows water to creep under it, and with the boat cabin flexing in cold weather I can not see that tape holding up. Recessing them so that the window was level with the cabin exterior would have helped, but the only sure way will be to use scewed wooden strips with a rubber compression ring underneath.

Mark, I never told you how it amazes me that you can get ANY work done at all and film at the same time. That would drive me nuts if I weren't already! I can only manage to film some after the facts walk throughs and talk throughs etc. IDK how you manage!

from electro, to jazz....this week Mark...i dont know what to say. it sounded like a dishwasher on repeat. :)

I would still put screws on those windows

I had same issue with west system epoxy pumps when they get old. If you buy yourself a cheep set of digital scales and mix it through weight, you will find a perfect mix every time. Hope this helps

Mark I have used the 3m tape many times and will tell you that it will end up lifting in spots in a year or two, it may be fine for a short fix or a boat that is forever going to be a coastal vessel, but to sail across the Atlantic with glued windows should be something you reconsider before doing so. Another way to put it it, is are you willing to risk your life in the Atlantic on just glue! On a positive note its great to see the progress you have made so far with this lady.

The yellow doesn’t look bad at all. Blue white and yellow, it matches 💪

The 'bashing strip' is actually a rubbing strake. Traditionally made of a hardwood such as teak and often covered in a corrosion-resistant metal. They are regarded as sacrificial to protect the hull so should be fitted so that they are easy to replace.

Looking good Mark, one thing, screw the windows down, heat, sea water, rain, storm, wind, time after time, will tear them off in a jiffy mate.😉👍🥰

Mark, I think you have made a great purchase with this boat and she should be able to fulfil your dreams if properly repaired and outfitted. Through hulls, windows and hatches are always vulnerable on a boat especially in heavy seas. For your and any passenger safety I would urge you to re- consider your window solution. Maybe fine for fair weather but need to be prepared for the worst. Best of luck.Great channel!

Good choice on the through hulls. You know it makes sense.

Frame & screws on the windows sometime before you go offshore. Can't ever be sure of tape & sealant. Nice work.

Mark is making the marks! Awesome videos Brotha!!

18:34 When air is trapped in the pump you can get these going again by pressing them down and sealing the tip with your finger when releasing for the up stroke. Repeat a few times, then the pump should fill with liquid again.

It will be intresting to see how the windows hold up, but it wouldn't be difficult to add scews if the tape dose fail

I like the window colour .. unconventional but not totally abhorrent! 😜

Yellow! Your biggest fans will be the bees. 🐝

Excellent progess, the windows at first glance were questionable but by the end of the episode you have a sound solution. You can still clamp them down if issues arise.BTW it is a Rub Rail.🎉😂

Good on you for cracking on, well done. The windows look good however I’m also concerned about how well they’ll hold up at sea and in the sun: The idea of using double sided tape on polycarbonate or glass windows on a boat is common but the tape is actually only to provide an initial holding bond while you get the windows in place and to act as a dam and spacer, stopping the mastic from flowing inside when you press the windows into place and providing a level placement. The tape can not be relied on for long term adhesion in this application. I use @10mm tape and a 20mm bead of mastic. The actual long term bond is provided by the mastic and ideally you should be using something specific for the purpose such as Sikaflex 295-UV. If the surface preparation is solid and everything is down correct ply you shouldn’t actually need screws through the polycarbonate but there is a lot depending on all of that preparation and application. IE if the paint below the mastic fails it won’t matter what tape or mastic you use to hold the windows in place. I don’t know the product that you’ve used around the windows but a quick look at the information on it on line suggests that "adhesion to plastics can vary”, which is not a good indication of its longevity in this application.

rub strip or rub rail ...Mark......looking good.......if you are going to do fiber glass work on the cabin tops, you might think about adding a drip edge above the windows to shed cabin top runoff....every little change makes Mahi more wonderful...cheers

Silvia is a star!!! the secret to spray paint is to do the first coat really light, just enought to make it a bit sticky, wait 15 minutes and go for second coat, but remember first coat light! By the way windows are awesome!!!! you can always add a woodden frame later on

Fantastic job you are doing everything looks fantastic. Everyone is right about the windows everything needs to be ship shape especially the window frames. Perhaps bolts with FIBERGLASS liner going right through the wood

Your doing really well and will have a super cat when done.

Thoser windows :-) Mark living up to his rep as the bodger king....I would't even trust that in my garden shed, never mind blue water sailing. This channel just keeps on giving.

Like several other comments Mark I would like to see some screws or stainless nuts and bolts on the windows.

Good job

Put the spray paint in hot water shake well . That makes a huge difference

Lookin good!!

Free Range Sailing did a massive rest including their windows about 2 years ago. Might want to see the way they did theirs. I really like Andy at Boat Works Today. Free Range Sailing had more info and lots of details, very comprehensive. I'm using their techniques for my refit. Cheers, S/V Cork~Texas 🇺🇸 ⛵

I agree with almost all the comments below never skimp on Windows Engine and drive train and steering and sails it looks great but you have to be set up for the very worst nature can throw at you Rock on Young man.

I also agree, you need some fixings on the windows, a heavy sea will rip them off, I remember a customer blew in a port hole(fish eye type) by throwing the helm over on a Sunseeker with bow thruster on. Better safe than sorry.

The pump isn't Furked its just needs priming all you needed to do was block the spout with a fingertip and pump a few times allowing air out and not in once the fluid hits the valves inside they will work fine. I am personally not a fan of the windows but as you say we shall see. Great move on the thru hulls I was always a bucket and chuck it boaty until the missus insisted on a "proper" sink and Toilet.

Did you notice how good the paint looks when looking at it from the back of the polycarbonate? Wonder if you could of put vh tape on top of the paint and let the painted side shine through. The paint would never scratch that way. Then use some small recessed screws perhaps covered in epoxy resin if needed. And then the bead of caulk around the edge. I really worry about just tape holding them on. The polycarbonate looks nice and thick so might be heavy with gravity constantly pulling them down. Heat and cold constantly expanding and contracting the tape. Anyways, hope they work but can always add some screws I guess.

I would put a metal ring around all the windows with sealent.. Silvia is a trooper..deserves bid hugs and a meal out. Great job so far bro..🎉❤

Good progress! Two things: I agree with the chorus that the tape isn't a long term permanent bond. It will lift in a year. I'd make some hardwood clips and screw/epoxy them on. Or get ss clips, but it's easier to seal up wood IMO. Make a batch of 1" wide hardwood clips, screw and epoxy them, then seal up the screw heads with plugs in epoxy and coat and paint. Nothing to leak, windows stay in place. Regarding the epoxy pumps, I hate those things. Just get a gram scale and use that. Very easy and fast and accurate. West System says 5:1 by volume is also 5:1 by weight.

You might consider adding a "tunnel" below the deck, forward of the motor mounts. Then have hatches to access the motors. This also can allow you to "crawl" between hulls without going outside during bad weather. If planned well, you can get a bit of long storage across beam. And you can use it for electrical conduit that is easier to service. In any case, good luck.

The windows look good. They should last a good long time, although, starting in about 4-5 years, you should do a yearly inspection of the seal. Next, Looking at the current colors of the boat, I almost wonder how a tri-color scheme would be. Blue hulls, white cabins, and yellow accents (windows, beams, etc etc) It would be a more bright and lively boat. Also, the white cabins would be a tiny bit cooler in the tropics. Finally, the floor(sole??) plates/hatches, at first I thought a clear varnish finish for a natural wood look, would be nice, but I realized that painting (presumably white) will make the interior brighter, and will require less lighting, and less power consumption. Again, nice job, and I am enjoying your videos.

The fat bead of silicone is definitely good insurance to hold and seal windows in place

Windows look sick! Pop some screws in them though. Yellow on white with blue bottom would be a real head turner! Music is on point again!

Love it!

Try sitting your paint cans in a bucket of warm water, the heat will kinda "thin" the paint and will help it flow better

I used the 3M tape to replace all the windows on my yacht over 4 years ago. They were over a curved fiberglass surface and there has been absolutely no movement or lifting. Looking at your flat base I can see absolutely no concern over possible failure. The best thing is there are no screw holes which are are the source of stress cracking and failure.

As a 20 year live aboard yachtie who refitted his own boat i suggest those windows the way they are fitted are about as useful as a back door in a canoe when you hit 20 mtr breaking seas in the Atlantic or wherever. I was also a merchant seaman for 40 years and saw the power of seas as they bent cranes and ripped containers off ships. Best of luck with that bodgy fit. Youll need it.

Go Mark. Nice to see a gal giving you a hand

Put strong underwater lights in your through hole for safety in dark water especially since you don't have depth sensors and it would look cool night fishing around the boat

Love your video’s Mark!! Thanks and can’t wait till the next week. Grtz. from the Flevopolder

The windows look good, the job will get you out there quicker. Watch out for cracking and degradation of the tape through UV exposure over time as all the materials will expand and contract at differing amounts each day. Have a couple of window plugs ready made if the worse happens at sea. Onwards you March Well done!

Might want to consider using a router on your windows to make them flush with the out side and use epoxy with filler to seal edges

Even if it isn't my kind of boat ( I like wooden sailboats) I admire the work he's doing!

Looking good Mark, i do agree with other’s who commented secure them windows, but i don’t know that product tbh, it’s possibly super strong, I’m definitely not sold on the no through holes, It’s a live aboard, you at least need some basic plumbing, A decent toilet, (head) and a few sinks, maybe eventually a water maker? But that’s entirely your call.. but yes she’s looking good, I would probably change that 70’s blue to a Royal Blue.. again your call..

I have used this same method - VHB Tape, and silicone sealant (specifically DowSil 795) - and am very happy with the results. And Yes, Andy is an Excellent source for info.

Rubbing Strake?? Looking good! Cheers, Ian in Blackpool

VHB tape is very good. I used it to stick speaker drivers onto wood to make some very thin speakers (video on my KZfaq channel). They hanndle mechanical vibration well. Not sure how this tape will handle heat and UV light though on a boat.

Thanks for taking me on this adventure.

Your definitely gonna need to use screws for the windows the salty air will do a number on the 3m tape in no time remember drill a pilot holes good luck

It’s actually coming together so fine, I’m really proud of you. Have you thought about i Selling the mast and installing TWO masts as VAKA s are supposed to have. . ? Advantages = low aspect ratio low no breakages wind under waves, The polynesians weren’t stupid Get two wooden masts?

Lots of commenters on here don't know anything about VHB tape. I just had to remove some really old vhb tape & it was not easy. It's used to attach windows on high rise buildings! I've got "portvisors" attached with 1/8" vhb tape on 4 ports. I kick and bump them accidentally all the time. I'll break one before that tape fails. Ignore anyone who says to put screws through the windows. That will cause them to crack and fail. I had to replace both of my fixed ports for that reason.

When you think youve rattled the can enough rattle it some more and it will also work better if you can use it in the upright position or vertically so stand up the piece you want to spray.

Mark this boat is going to look really cool when it’s finished. The more I see of it the more I like the shape and can see how it’s going to be like a Land Rover for the sea!

I’m loving these videos

Steady progress. Hard to believe it’s the same boat from that mooring.

A good tip when using tins of spray paint submerge it in hot water for 5 minutes before you start spraying. you'll find it sprays much more evenly and you'll leave nothing left in the tin!

Set up some plywood benches,save some wear on your back +get a better angle on spraying!shake can every 60 seconds or so!

A bit late now, but I was thinking those panes could have been inset in the frame slightly, with beading on the top and sides but not the bottom edge. I would have ordered the plastic a little oversized in height, so that the bottom edge could be heated and bent outwards in a J shape (about 3cm). The rain would run off easily. But what you did looks OK to me! Keep it up squire.

Awesome mate, the music is 😎 cool, 70's can go a little " Gorge and Mildred " but still better than most KZfaq music, boat is looking good, coming along well.

looking good brother!…glad you decided to eliminate through hulls…smart move… i am going to be replacing poly windows on cat soon…didn’t realize i could use tape without screws…but, i had planned to use tape and bevel the edges of glass to allow for larger calking bead…i hope you got enough meat in that joint…looked tight…i hope it holds and you have sealed dry windows for a long time… i know you’ve got a lot of work remaining , but i still think you got a real bargain on a very well designed and built warrham… i think if you can manage to place the helm with wheel steering under large well protected covered bridge deck you’d really love it…i really don’t see the need for dual helm , even with the wide beam…i rarely use the port helm, mainly because the other one has instruments and engine controls…i have no problem docking to port after getting used to it…in fact thinking about doing away with other helm altogether and using space for extra storage… keep on plugging!…pardon the pun…

There we go mark!!!! ⛵⛵⛵⛵⛵⛵, Awesome I've done the same with VHB tape, it sticks like crazy after 5 min, I've tried to push them out full force with 2 hands, and the 1cm thick polyester bended in my deck, didn't came off a mm. There will be a lot of people who have an opinion about this solution, but I've been told that the burj khalifa has VHB tape on all windows, after that I was convinced ✅😁👍🏻. These new windows look amazing, and nice light inside.

Nothing wrong with your music selection (99% of the time 🤣). Windows look great! Wish you would get some 2”x4” lumber and some sawhorse metal supports and a sheet of plywood and make yourself a table or two. I think it would make things so much easier for you. I absolutely LOVE your project and of course you’re not so bad yourself!! 🤪
