common ground

Frankthere should be only one common ground on a boat so as to avoid electrolysis and there isn't the right place. Your post isn't clear - by "main" I assume you mean the mast base. The grounding wire you see at the mast base should go to a keel bolt and is there to carry an electrical strike to the keel and water rather than throughout the hull. If I misunderstand your question, hope this doesn't further confuse your issue.Don
