The cooler seat has cracked in a number of places. I've been pondering the idea of replacing it with a fiberglass structure that would be bolted to the deck and have access so it could be used for storage. I don't even know what that would be called. If such a thing is available, it would allow me to either retain the bench cushion or replace it with two individual seats that could possibly swivel. At the risk of offending those readers who think I shouldn't change from a classic style, has anyone done this? What would that structure be called (hard to Google without knowing a name for it) and where would one find it? Thanks.
