Marine Foam ??

Hammer, i guess you do a lot of diving, one thing I did to my rod boxes was put strips of teak connecting the rod holders to each other along he bottom of the rod box. I left a gap between the bottom and the first strip for drainage. This is a great place to throw mask, fins, gloves,bottles of spit(no fog). etc. It keeps a lot of clutter of the deck. I also put 3" pvc tubes in the gap between the hull and the liner you are refering to and use this for a storage tank for a fresh water wash down.The great thing about having a boat is you always have something to do.
