Well, before the purchase of my new old Catalina 30 1985 the surveyor said mast needs to be grounded for lightning protection. The sailboat place quoted $1000 to do the job. Boat US said my insurance is contingent on this being done in 30time days. Could I some how run a 6 gauge solid copped wire from the chainplate to a keel bolt? If so is it possible together it through under the liner? Anyone done this. Any suggestions appreciated. Not enthusiastic about spending $1000 . Thank you. Tom
