I bought this boat about two months ago, with the understanding that it was going to take some work to get it back in the water. The engine was locked up and the interior was gone. Fixed the engine, and before I went ahead and did the interior thought I take a look at the underside of the floor in a few spots. What I found was not good. Where the stringers go is dust. The foam like a big sponge of water. To do the stringers I know the engine needs to come out but is it okay to leave the boat on the trailer. Also the boat was at one time had a ski locker and a cooler in the middle of the floor. On the bottom of the two is a flat layer of fiberglass with a hole in it to let water drain into the V part of the hull and back into the bilge, or water from the bilge to drain into the locker and cooler. Anyway thought it was a good idea and was woundering if it would hurt to do that to the entire hull to stop water being trped in the front part of the hull. I have done a few searches and douglas fir seems to be the choice for stringers, if my info is wrong please let me know.
