Here's another little interesting thing. This boat (mine) was built in 1979. Apparently there were no "standards" then?
The manual says:
POLYSTYRENE (Styrofoam for example) is the least expensive foam available, but it
will dissolve upon contact with gasoline, is brittle and will crumble when left exposed to
sunlight. Builders who choose to use Polystyrene foams should cover them with
plywood, vinyl or another material, or enclose the foam in compartments where it is not
exposed to abrasion, the elements or sunlight. Polystyrene should not be installed
near the engine or bilges.
This stuff is polystyrene and is not covered by anything. in fact, the rear hold has the gas tanks stored there (on my boat) so, it bugs me this stuff is even there.
