: : We are building a Double Eagle in timber. The Glen L instructions calls for a 1 sq.ft copper external grounding plate. can any one explain to me what its purpose is and why here in Australia, no fibre glass boats ( the Double Eagle is sheathed in fibre glass ), are fitted with such grounding plates.
:
: That plate they speak of is used for 'bonding' the fittings in the hull. It helps to prevent electrolysis corrosion of metal parts in the hull.
: A good question would be why has sacrificial zincs become more popular than this system?
