I have a 1986 15 1/2' Grumman Renegade boat. I dont have any place for storage except for under seats. A couple of lift jackets and it is full. There is a piece of carpeted plywood on front of boat where the front fishing seat is at. Does anyone know what is under there? If there is nothing I want to cut a hole and make a storage area. If there is foam does it hurt to remove it?
