Epoxy your hull when there is no osmosis?

[Gludy]

I have just been advised that because I am leaving my boat in the water all winter despite the fact it will have two new coats of ant-foul after a proper ub down, I will need to epoxy it??

The hull has been tested and show a super low moisture content - in fact no different to the super-scructure. So there is no sign of osmosis whatsover.

Does anyone else epoxy coat their hull when there is no problem on the hull so as to offer extra protection?

Thats bollox, IMHO. Years ago when osmosis was an issue with grp boats, an epoxy treatment may have been beneficial but, you will have long got rid of yours before any osmosis shows up, if ever

agreed. this seems a whizzy way of extracting some loot. Whole loads of boats in the med sit in the water year in and out, no osmosis.

winter-wise much more useful to shut the boat and have a cheapy dehumidifier positioned at the lowest sensible point in the boat draining to a shower say, set timer to say four hours three times a week so no damp get going to harm v expensive internals. Externally, lash some creamy polish on any parts exposed to the sun and leave it all smeary. then rinse and polish off the next season, No thanks, don't need guardiennage but a bloke who is around can be paid to keep an eye on things for a few quid a month and call you if things happen.

My thoughts exacly - it is just that I have been handed this advice and was a little amazed as it meant I would have to re-write my understanding of it all.

Its an expensive treatment and I can see no point in doing it.

Is it best to remove all the old anti-foul before applying two coats of new - or is just a good rub down to form a key preferable?

No, I dont think the old antifoul coat has to be removed unless its flaking off badly. It may be a good idea to abrade the old antifoul to give a key and remove any loose pieces but I'm sure most boatyards dont bother and just slap the new stuff on

Re: Epoxy will DEVALUE your boat

I agree with the others, total bolx. I'm not sure the year of your hull but guess it has the modern gelcoat and fist layup resin that avoids osmosis.

Epoxy might actually devalue the boat. A buyer's surveyor will know you've done it and report it. Then buyer will think ooooh this is an unusual dud squadron. Why would Gludy have spent £££ on epoxy unless it was an osmosis dud? You can protest but they might not believe you. Then the story will go on a forum and the whole world will know about that Sqaudron in Cardiff, you know, the dud one that got an early attack of osmosis and the owner tried to fix it quickly with epoxy and not tell anyone, but we found out, so best avoid that one, eh? If I were buying a recentish squadron and it had epoxy I'd be suspicious.

I also agree, just rub down the old antifoul. Who cares about perfect finish down there

Re: Epoxy will DEVALUE your boat

Agree with all the above. However, my understanding is that after a few years it's best to remove all the antifoul (various ways of doing this) and start afresh.

Re: Epoxy will DEVALUE your boat

People say it's best, but why? Assuming it's not gone massively thick and unsightly, just stick the new stuff on. Anti foul works on surface effect, doesn't matter what's underneath it. It's just one of those things that "people say", imho
