Soft floor....well....rotten floor.

Nobitchin,

I have same spongy deck problem on my 18 ft Seacraft. I took fuel tank out to check and drilled a few holes in spongy area. There is plywood between layers of glass where console bolts to the deck and balsa between edge of plywood and inner hull. The deck is cracked which caused water to enter balsa and rot it. The plywood rot started where the console was screwed to the deck.

I agree with Fellow ship's idea of cutting away top layer of glass with circular saw and removing rotten wood, if you are not raising the deck. I am going to remove the live well forward of the transom and will then be able to see condition of stringers and flotation.

There are many good sources on replacing rotton core. I will probably use Divinicell and resin instead of epoxy.

Hey can you put up some pictures...really interested in seeing as my boat has the same problem!

I will take some pictures and post as project boat once I figure out how to add pictures. I decided to replace the rottted balsa with balsa as I believe it adheres better then any synethic material and has greater strength for the weight. It should be fine as long as any holes through it are properly sealed.
