Waterlogged Flotation Foam - Saw Sugar Scoop Off The Boat
Ғылым және технология
The goal is to add a boarding ladder to one of the sugar scoops. Because of the round ended shape of the scoop, I have to saw the end off to make a flat spot for the ladder. As soon as I sawed the end off of the boat, water started running out of the floatation foam.
This should serve as a lesson about two part expanding polyurethane foam. Even the "closed cell" foam will soak up water like a sponge. Closed cell just soaks in slower.
If you find waterlogged foam, don't cut it all out unless its a problem. In this small space, outside of the main hull, I guess its not a problem for now. If you leave your waterlogged foam open to the air for a while, it will dry out. With such a large opening, this dried out after just a few days. I was able to lay in some fairing filler to harden the surface, then laid eight or ten layers of chopped strand mat over the open end of the sugar scoop. This would be thicker if it was on the main hull.

LOL, I always underestimate the time work takes, so I wind up with projects like this.
I’ve just finished sealing up my foam and when I did the suns heat pressurised the wet foam a pushing water out Definitely a job for late summer if you can wait for nature to work for you. Drilling 3 mm hole in the bottom helps to drain. Then I use milliput black epoxy to plug the wet hole to then glass over

Thanks! Some real useful advice there. Drilling a hole in the bottom seems so wrong, but probably the best way. Wish I knew about the black epoxy when I fixed the weepy spot where water leaking from the foam ruined a fiberglass repair. I might drill a hole in the other sugar scoop after reading your comment.
Time consuming work - but it pays off! Do you expect more water soaked foam elswhere in the hull?

I expected the foam under the floors in the pontoons to be saturated because there was two feet of water and tadpoles in the boat when I first got it. By the time I got around to fixing the "weepy spot" where a through-hull fitting had been glassed over, that foam felt damp but you could not squeeze water out of it. I really don't understand why that wasn't completely saturated.
salt water or fresh

Rainwater. I still have to glass the steps on the sugar scoop. They leak somewhere topside.
Do you ever feel you might be wasting your time on this project?

I think that wasting my time was the actual goal. Its been months and the boat looks almost the same.
