Cabin top repair

Oh wow thanks for that! Looks like I might need to do a bit more research before tackling this job!

 

First we are not talking about the deck, it's the cabin top. Second, the hull is solid fiberglass not wood.
This boat was probably not fitted out by the hull builders (Tyler UK.), and since there were several yards finishing the bare hulls we can't say from afar how the deck and cabin are done.
The definitive proof it's a canvas top will come when the OP removes the trim around the cabin top, it covers the staples or nailes holding the canvas down. Even then we have no ideea what's under those pine boards, that will be revealed by further surgery.

A new traditional canvas top is certainly a possibility, but it doesn't have any advantages. Restoring the structural integrity of the cabin top involves the same work, and canvas covering isn't easier, faster or cheaper then fiberglassing, especially for a beginner.

 

On top of that,a canvas replacement is likely to have a shorter life than the glass alternative.It might be pointed out that the original has lasted quite well but the epoxy/glass option should be a once only job.

 

I think some wires may have been crossed somewhere. My hull is timber and was built in Sweden. After having another close look today the cabin top is canvas topped with a very thick layer of paint (?) over the top.

 

The canvas top will be quite a bit harder for an amateur. If you go that route, I suggest you find someone who knows how to do it.

fyi~ in the original post, it was you who said it was fiberglass, so easy for others to get that locked in...

 

That would be what's commonly called the "O-36" not the later glass O-35. Is this your boat? Drawing – O-36 – OhlsonYachts https://ohlsonyachts.com/drawing-o-36/

 

I said the cabin top was fibreglass not the hull. And yes I was mistaken about the cabin top as I’d never come across a canvas top before so at first glance thought it was delaminated fibreglass.

 

That’s interesting as she has a metal plate stating she’s an ohlson35 ? Also Trim, Aja and Ellida are all Ohlson 35’s with wooden hulls? As far as I have read the Ohlson 36 came after the 35 and were modified to qualify for the Bermuda race standards?

 

The drawings I linked are also labeled Ohlson 35. But today the wooden boat is known as O-36, and that's important because if you search for info it's all labeled with 36 not 35.
