Nice repair. I recently had to repair a similar situation on my Bayfield 32. The core (balsa end grain) was rotten under the pedestal from some PO putting holes where they didn't belong and not sealing the core. Mine was smaller and I attacked it from the bottom as well. I cut a 2' x 2' section of the bottom skin from below. (original coring was only 2' wide-- it's a narrow cockpit
floor) I then cut out the old core as well. This was about half wet / rotted and half still ok. I used a multimaster knockoff (Rockwell sonicrafter) for both tasks and it was a great tool for this. I then epoxied a 1/2" thick sheet of solid G10 (epoxy laminated fiberglass) in place of the removed core/bottom skin. I taped the edges with 4" and 8" bi-axial tape and epoxy
. The repair is *VERY* strong. I think that area of the floor gets a lot of stress as the pedestal is a long lever that is used as a grab rail almost constantly. Lots of torque applied to that section of the floor and I think a solid floor there is warranted (IMHO, but I'm *NOT* boat builder
, so what do I know.) Just seems to be a lot of failed cockpit floors in the world. I'm also adding a smaller 3/4" layer of G10 between the pedestal and the floor. This will put the base of the pedestal at the same height as the teak
cockpit grate in the rest of the cockpit and keep the base of the pedestal off of the almost always wet floor. Also rebuilding and painting the pedestal, but that's another story...
