Ok my 1969 18ft glasspar that was going to be some new seats and off to the water has turned into a major project. Right now I am on the floor, I have some of it cut up, and this is what I found and what I need some advice on.
It is a tri-hull and there is a "ditch" that runs down the center to channel water back to the pump. most of it is 6 or so inches deep, it comes up on each side and turns outward towards the sides of the boat, it has some sort of webbing in it (I think for strength). Anyway it is all filled in with foam along side of this then there is what is left of a 1x10 board that fits between the foam and the lip that turns outward. so basicly the wood is just a 1x10 laying flat on top of foam. I didnt cut real close to the edge yet but I think there is another piece of wood along the edge with the foam inbetween the 2 pieces of wood. The foam inbetween the boards is about 6in wide and veries in thickness due to the shape of the bottom of the boat. I hope you understand what I am saying, any way I was looking into some new foam and dont know what to use, seems everyone goes with 2lb. but I wonder with the way this boat was built if the foam doesnt serve as some sort of structure also, so should I use 4lb.?? Then pretty much from what I read I use a epoxy to coat the wood and put it all back together. Sorry this is so long but I tried looking at everyones pics and they dont even come close to how mine is built. Thanks
