Re: 1984 c&c 35-3
My guess is that area under the pedestal is plywood core. The rest of the cockpit is mostly balsa core. Lean heavily against the pedestal. If the sole flexes your core is likely shot. See attached picks of the core fix on my 29-2. If the plywood is wet then drilling hole/epoxy fill won't work. The plywood holds water and it has no way to get out. The plywood is shot. solid glass area under pedestal and rudder post is now 1-1/2" glass. No water problems anymore and a really solid pedestal. Well worth the $2500 it cost to have it done.
