I have progressed in my H25 rebuild to the point of setting the main bulkhead and mast compression post. However; upon close inspection of the bilge area it was apparent that there was rot in the floor timbers around the limber holes and any other holes made for wires, screws, etc. I elected therefore to cut out the floor section and rebuild all the floor timbers. In the floor at the main bulkhead there were essentially 3 components; 1) the main timber, to which an (2) additional timber was laminated to sit under the bulkhead, and (3) the framing in the floor pan. In assembly it appears the floor timbers were glassed to the hull and then a structural goop was applied to the tops of the timbers and then the floor pan/structural grid placed on top and bedded into the goop. This created many voids that trapped water. I will build an e-glass web floor to join the hull to the floor pan and epoxy new mahogany beams in place. Everything will be sealed in glass/epoxy for a complete waterproof assembly. I'll either build a flange all around the cut out and screw the old floor section back to it or build a grate floor of mahogany finished bright.
