Re: Minor water damage to rear deck, Your opinions and solutions count
Ha, just done this on the same boat!!
I had a soft area that I found was caused by a leaking cover - it was rotting from the top down and not from the bottom up. Here's how I repaired it.
The Capri has a 1/2" deck so I got a piece of new ply and screwed it to the existing deck and then marked where I wanted to cut so that I was cutting into solid deck wood.
I then set my circular saw to 1" depth and started to chop out the ply wood. After finishing the cut I unscrewed the old piece of deck leaving me with a new piece of deck that would drop into the hole I had cut. Using strips of ply, I screwed them in under the old deck edges, creating a shelf for the new piece to fit to and I dropped it in and screwed it to the shelf pieces. I coated the underneath with several coats of Minwax varnish - should have used resin but it hadn't arrived when I did this.
Anyway, I then laid down a layer of chopped strand mat and used poly resin over the whole area with about a 6" overlap over the old deck. When this was dry, I sanded the whole deck and laid down f/g mat with poly resin - this was to waterproof the old deck which seems to only be part glassed in the factory.
I finished off with two coats of epoxy resin over the entire deck to seal it and ensure that the brittle poly resin wouldn't be affected by any flex in the deck.
Finally I laid new deck carpeting (cos it's a play boat, not a work/fish boat) and it's really solid now.
By the way, I did check the stringers and transom when I had the deck up - luckily in my case everything was dry and solid - it's an outboard model and I think they stand up better than the I/O models in this regard.
