We used to rent a 34 Pilot of about that vintage out of Sausalito. Nice boat, but on the one we used that space was pure storage, uninsulated. Knock on it from the inside and out, that'll tell ya pretty quick. You can buy generic conversion kits to insulate and cool. You are right over the engine space there as I recall, so insulation is a big must.
