I recently purchased a 1966 Sleekcraft real cheap, one thing the guy told me was that the boat was real heavy cause it was well built, the boat is foam filled. After doing alot of work fixing on the boat I noticed that most of the foam I come in contact with is wet. This boat had alot of leaks thru the windows and bow rails, inside the cuddy cabin all the storage places were filled with water, there's 2 spots in the back of the boat they made for thru hull for bait pmp and transducer, they were filled with water due to water seeping from foam, is there any way to get foam to dry out. I got most of the leaks fixed, I think that's were the heavyness comes in, it seems to float ok, in the next couple of weeks I will test the new engine so I will see how it operates.
