When I pulled up my floor, there was foam at the very front of the boat where it comes to a point.. and around the bilge area. Inbetween that was mostly empty space except for 3 small hunks of styrofoam. Yes thats right STYROFOAM! This was the original floor which means that was how they did it at the Sea-Raider factory. Do you guys think I can get away with just the foam in front and back? I imagine those 3 hunks measuring about 6x4x4 didnt do a whole lot. Im pretty sure I can leave that space empty without too many worries. Just need the experts opinion. Thanks!
