forming galvanic cells will overwhelm that protection. Electrical grounds shouldbe led to ground terminals at the switchboard or at the battery. Even certainaluminum alloys will act as dissimilar metals in a seawater environment. Marinegrade aluminum and stainless will react, but not as much as other metals. A copyof an activity chart is included at Table 1. Attachments to the boat should be madeusing marine grade stainless steel fasteners. Metals other than marine gradealuminum should be isolated using neoprene or non conductive beddingcompound. If in doubt, check with our Customer Service Department.CAUTIONMercury or mercury based compounds will result in severe corrosion of thisaluminum hull. Mercury in bilge water in a proportion as small as one part permillion, will result in extreme corrosion. Do not paint this hull with either mercuryor copper based paints. Keep mercury filled instruments, such as thermometers,off the boat. Be certain that no item brought onboard or used for repair or paintingcontain mercury or mercuric compounds.8
