forming galvanic cells will overwhelm that protection. Electrical grounds should
be led to ground terminals at the switchboard or at the battery. Even certain
aluminum alloys will act as dissimilar metals in a seawater environment. Marine
grade aluminum and stainless will react, but not as much as other metals. A copy
of an activity chart is included at Table 1. Attachments to the boat should be made
using marine grade stainless steel fasteners. Metals other than marine grade
aluminum should be isolated using neoprene or non conductive bedding
compound. If in doubt, check with our Customer Service Department.
CAUTION
Mercury or mercury based compounds will result in severe corrosion of this
aluminum hull. Mercury in bilge water in a proportion as small as one part per
million, will result in extreme corrosion. Do not paint this hull with either mercury
or 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 painting
contain mercury or mercuric compounds.
