Ric, very nice pictures. But Don touched on a subject I know  
intimately after refastening a 40' wooden boat. Stainless steel  
fasteners are rarely used on the hulls of wooden boats. First, they  
are too expensive. Second, they are subject to crevice corrosion if  
prevented from oxygen exchange with the surrounding water. The  
preferred fastening material is silicon bronze, or, if you have a lot  
of money, monel. Most likely the boat in Ric's picture was fastened  
with galvanized steel nails or bolts. After a while the zinc erodes  
and the nails rust.
