The old models didn't have closed cell faam.
I cut holes in the cockpit wall just above the seats. The holes are cut so that screw in covers can be installed about 6 inch ones.
I reached in and pulled out all the foam I could. I don't think the old boats were sealed between the sidewall and under the cockpit sole. I cut up some strips of closed cell foam and stuffed them in.
If I were to do it again I would put foam pernuts in plastic baggies and stick them in instead. I am still concidering boring small holes and using the spray foam into the area low near the floor.
Good luck

Early Lasers had foam in plastic bags which soon waterlogged. They went to rectangular inflatable structures.......not unlike the semi-clear collapsable water containers sold for campers. Fold a few up, squeeze them thru the 6" cutouts (future inspection ports and re-inflate it with a shop vaccuum.The boat can be dried inside with a shop vac (blow mode) on a dry day. Blow air into one hole, sealed with duct tape, and the air comes out through the other hole. The vac will blow warm air for a few hours (annoying the neighbourhood) but will eventually dry out the hull. ------------------

I too have traveled the waterlogged foam road. You can check it by reaching into the centerboard inspection port with your hand and simply breaking off a chunk and pulling it out. If its like mine was its probably soaked. I don't know if you could dry it out , it holds a lot of water ! I dragged it out the centerboard port piece by piece. If I had to do it agian I would use Tom's method and locate inspection ports on the side walls. I did not replace the foam in the floor but choose instead to put foam into the bow and lazerette instead. I question the usefullness of foam under the floor of a swamped boat. One would think it would want to turtle if the boat was full of water. But thats probably why I work on routers and not in boat design.. Hey on a side note I just got my new main sail from CL !

Thanks for all the feed back.
I decided to drill a hole in the floor and found no evidence of water or foam. The center board trunk had some water in it that drained out the back when I lifted the trailer high enough. In the back storage compartment there looks to be two cavities for foam.
The hull # is 1733, the guy I bought it from said the it was built in Scarborough in 1983.
Any one know anything about the foam placement on boats of that time?IP: 216.221.95.132 |

If you have an electrical snake, its very useful for foam exploration. I stuck it into the centerboard inspection hatch and rooted around until I could locate the foam. I appears to be sheets at least on my boat, which I believe is about 1972 vintage..
