Gabriel describes the practice of attaching a "sacrificial" metal of greater tendency to corrode to another metal which is to be protected. This is common for steel-hulled vessels (are Nordkapps *that* heavy?), which often have several-pound chunks of zinc welded onto their sterns and other below-water parts. Copper, being *less* active than iron or aluminum, would have the opposite effect, and would accelerate the corrosion if attached to either. About those aluminum footbraces -- probably eventually fail at the place the fastener passes through them, but not for a long time. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************Received on Tue Jan 26 1999 - 07:39:56 PST
