Couple of quick points. Countless boats have SS prop shafts and bronze props without any problems with galvanic corrosion. Countless boats have keel bolts, nuts and washers made of SS without any problems with crevice corrosion. In the unlikely event of a problem, the nuts and washers can be easily replaced with new ones.
Since you're committed to using wood for the floors and stringers, than locust, or another type of wood that's been pressure treated with a fungicide, is a much better choice than mahogany. Mahogany will not hold up well in a moist setting and S2 should not have used it for such an application.
After the old floors and lead keel were removed, I would have laid down about 3/16" of new fiberglass on the original hull surface. I would have started at one berth bulkhead and run it athwartship down into the keel sump and up to the opposite berth bulkhead. I'd use mat and biaxial roving. This new laminate would greatly strengthen the hull and provide a good bonding surface for the new locust floors. I'd cover the locust floors with about 3/16" of new fiberglass and bond it to the aforementioned fiberglass. The whole idea is to build a strong grid that is an integral part of the hull. |
