Polystyrene as boatbuilding foam?

Has anyone used polystrene as boatbuilding foam? It seems to be unaffected by epoxy, but does it have the sheer strength to be used in structural panels of epoxy and fiberglass? I have constructed a test panel (1 and 1/2 inch thick pink polystyrene from the Home depot--although 1/2" or 3/4 would be better in my view) Can these panels be sufficiently strong in shear resistance for it to be used as a core material rather than expensive "marine" foams. Anyone have experience with these materials or other foams that might be readily available and cheap?

This is how I would build a solid foam boat.
