Solution
There IS one solution to this problem which enables you to keep the boat, but it is not pretty. That is to fix it yourself. All it takes is some ugly, old-fashioned (relatively brainless) WORK.The good thing about this is that repairing fibreglass boats even in sorry condition keeps them out of landfills which is good for the ecology. These things were essentially made to be permanent, you know. --that means even if we choose not to use them any more.Soft fibreglass due to excessive water saturation is ugly but NOT unfixable. It just takes a heck of a lot of grinding, application of new Fabmat and mat, and more grinding.A few years ago I was looking with sad eyes at a very sweet little Ranger 23 which had been sitting for 5 years on poppets and was full to the bunk tops with rain water. Finally the yard moved it one too many times and pushed the keel through the hull (only a little but it was an obvious indentation). I would've taken it even then but title was turned over to a guy who had it properly supported and then went to work grinding out the softened fibreglass, laying up new Fabmat in the bilge, and refastening the keel (didn't even take t off).Was this worth it? Well, he got the boat for free. He did all the work. The yard forgave the last owners' yard-bill debt. In effect he paid for the boat with only his labour and now sails the boat I wish I'd got.Hunter 25s are not the most robust boats in the world to start with, so SOME oilcanning is gonna be there to start with. It sounds to me like the water got between the keel and the hull and through the then-open fibres sucked up some water. Have the boat lifted off the keel and let it dry (a season?). Cut a small piece out with the air saw if you have to. Then start grinding. Yes, it's a lot of work. But it is eminently doable. Fibreglass is doubly wonderful in that any idiot can do it passably well, and after a certain point it does not care about 'grain' and so forth so patching is not a structural problem. If I had the boat I'd do it (I am looking at a 1967 Columbia 24 with a hull crack on both sides now). People restore rusty cars all the time.If you are only concerned with money give it away to someone who will keep it out of the landfill.JC
