So, walking to the mailbox today to post a check for, quite literally, a boat load of copper canoe tacks, I got to wondering why brass became the de facto standard for canoe construction. Cost? Pound for pound, copper tacks and brass tacks today cost about the same. Strength? Maybe, brass is stronger than copper, but I don't recall seeing a canoe (canvas-covered or lapstrake) where copper fasteners were the major cause of failure. Dezincification? Copper wins this battle hands-down. Availability? yes, today it is much, much easier to source brass canoe tacks than copper. Still, it is possible. What other factors may have played a role?
