Hi Mark, sand everything that needs to be sanded and let it dry out, no point in filling holes until they’re as dry as possible and you wouldn’t be putting on the epoxy barrier coats until the weather warms up anyway so carry on with all the other jobs you need to do, i sand with 80 grit when preparing for epoxy coating, I did my hull this time with hempel epoxy barrier and it got an extra coat because of the price difference with other makes, it’s true that osmosis never sank a boat but no point in wasting money, just do the best you can to do it right once, I changed over to composite fittings this time so I won’t be doing them ever again and they’re meant to last the lifetime of a boat and mine is 44 already and solid👌
Hi Robbie. Thanks for this. Great advice. When we think of it like that it does feel like the pressure is lifted a bit. Good job about the composite fittings too. I'd rather do them now and have piece of mind we don't have to worry about them again 👍
Great video. Dont get too disheartened those things are sent to try you. You will get there. Regarding the corded power tools packing in try checking the lead usually where it enters the tool. They always go there. Or check for a carbon brush thats stuck or worn away.
Hi Mark, as others have said "osmosis never sank a boat". What you need to assess is if the blisters have progressed deep into the laminate thickness or only shallow erosion, this will inform you if the inherent strength in a given area is likely to be compromised. I would agree with the die grinder as mentioned in a comment, definitely not a flap disc as that will remove too much gel. As for the through hulls, I would not be confident using composite, I would (and have used) stainless steel A4 (316 grade), more expensive but linger lasting, especially for full bore lever ball valves. Don't be disheartened by the blister problem. When I bought my first yacht 30ft I used it the whole of the first season as I bought it in the water and didn't lift out. During the sailing season I built a multi adjustable cradle for her and during liftout in autumn while sitting her on cradle to my horror noticed the keel kicked to one side and centered again when she was lifted slightly. Had a surveyors opinion and advice which resulted in me having to cit out GRP saloon floor, remove wooden mast compression post and all 1/2" plywood cross floors, sand clean all accessible inner hull, add approx 18mm extra laminate (biaxial cloth and woven roven alternate layers with epoxy) then make and completely encase new 35mm cross floors with some extras added, then make good all the aforementioned prep work. To be on the safe side I also had the hull lifted off the keel, examined the 10-3/4" galvanized studs, cleaned the mating faces and resealed/rebolted. Followup visit surveyor took a look and said "f*** me that definitely Clyde built", that was 18yrs ago and have never had a problem since, not even in 10ft high waves around Innishown head.😊 I'm confident you will get through the stomach dropping episodes.💪
Are you in the same yard? Its no setback. Take a flaper disk to them. I would tarp so no water down the sides. Put a turbo heater under so the heat runs up a few times. Let it sit and dry see what others appear. That thru hull looked as if it had some life left. If you are pulling it out every winter you can space out some projects. Keel bolts and rutter should be checked. Your gettin gray😂 Merry christmas.
Haha that's boat work making me gray 🤣. Good advice. Just worried how long this all might set us back with everything else. Yes we arr in the same boatyard
Hiya. I had blistering on my hull. It's not as big a deal as some think. I got a die grinder from Lidl and spotted the blisters with the stone die. Then leave to dry. Fill with thickened epoxy sand flat and epoxy the whole hull. Gimme a shout. I'm local to you
Hi Ian. How long did you have to leave your hull to dry? Did you use a tarp to cover it? When you say epoxy the whole hull do you mean with a barrier coat? If so which one did you use?
Another Thru Hull removal method is to hammer in a wooden plug and then use a holesaw to cut through the flange. Do you work full time as well? So that you can only work on the boat on weekends?
Osmosis never sank a yacht grind the blisters out then epoxy filler them it always looks worse than it is chin up she's a lovely boat.its your time to give her what she needs 😊
Do not worry about it….. believe me that’s blistering and a little bit of osmosis…. You need to get someone really in the know to assess and don’t take the first opinion my hull got epoxy treatment on my beneteau 390 10 years ago… you have done quite alot of the work but may need to dry out for a while before coating, the hull is only one small piece of her!!! You have got plenty of jobs to do before the big launch in 8-10 months, do most of it yourself to keep the cost down and get specialist in to sign it off… will make great content… guaranteed your channel will grow, keep on this path if that’s where you want to go 👍
Great video, it’s a labor of love, she will be awesome, no worries keep up the hard work!

Thanks Nigel. Yeah we just need get heads down and keep on working away

I haven't seen that method. I'll check it out. I work in healthcare so do a variety of shifts through the week

Grind them out and get the dry, bit of filler and epoxy coat. It will grand.

It’s fine. Just putty it sand and barrier coat.
Do you not know what a sander is?
You've written this comment twice. Clearly know what a sander is. If you don't know, you can see one being used in this video
Do you not know what a sander is? And hell! I piece of flat bar and some adjustables would have spun the through hulls in a second
You've already asked that. And an adjustable wouldn't have worked inside the boat without taking cabinets apart to get at it.
