My 33-2 is stiff and solid, I would be surprised if a similarly-built boat would bounce. Dennis suggest a few excellent approaches to repair however I would suggest first checking how it was built at the factory, and what might have failed. Any deck I’ve worked on had some sort of flat core (balsa or plywood typically) sandwiched between the deck and an inner skin. When the sandwich delaminates the stiffness is lost. I’ve been on some really bouncy decks that lasted that way for years. (It would drive me nuts…) If it’s the cockpit sole I’d expect that water may have entered around the base of the steering pedestal. Is it stiffly mounted or does it move? If you add a stringer to back up a delaminated sandwich you may not really address the issue or the flex. The challenge is likely access to the back side, the rebuild work itself isn’t that difficult. Dave 33-2 windstar.
