First post ever been lurking for a long about a year. I'm a newbie to boats. Me and a friend bought a 76 Sanger Super Jet a little less than a year ago. Took the seat out to find a big rotten hole in the floor. I was going to just patch the hole in the floor but after closer inspection found that the floor had been replaced before and was not done very well either. I ended up removing the entire floor to find more damage from foam under it that held water like a sponge. The floor that I removed was not even in the location of the original. It was just set on top and glassed in really crappy. Heres some pics of my progress.
I plan on coating the bottom of the floor with a coat of resin before glassing it in.
