Re: Bonding and Grounding of Underwater Metals
Without wading into the discussion about what is "right", I will offer at least one data point: Our 1983 Pacific Seacraft 37 has no bonding and I believe this is original. All seacocks are isolated, .i.e. no bonding wires. We do have lightning ground cables that run from the chainplates and mast to a dynaplate. The Keel is not bonded electrically to anything.
Our bronze seacocks are all original (Groco model SV with rubber plug spool) and in good working condition with no dezincification visible on valves or thru-hulls.
