Ok so i just picked up this boat for 50 bucks and i knew it needed work the floor was rotten and the transon was shot too.. so i pulled up the floor to find expanding foam underneth that was water logged so i started to take all the foam out and ended up finding that there is no stringers at all.. now that all the foam is out the boat is really weak.. so this foam must be struceral. now in order to fix this boat i need new foam.. so i was wondering about getting someone who spray foam houses to spray the boat hull.. any ideas on how to do this? i can post pics to show what it looks like later
