I have been thinking now that I'm on the other side of 40, I don't have to build stuff to last forever, just 15 years or so will probably do. Do yall think that foam stuff is necessary. Im going to pull it all out, the bottom half fills in the v's in the bottom of the boat and soaks up water. If it is then im going to lay down some thin aluminum over the floor to keep the v's open to allow the water to drain to the back of the boat.
