Finally the day has come to replace the 30 year old rigging after an adjuster rusted through on the forward lower stay. Luckily nothing lost but more of a wonderful day of sailing and no injuries with the mast and sails left intact. My question has to do with disconnecting the electrical for a VHF antenna, steaming light, and wind instrument. Is there a simple disconnect for the wiring or does it run to the instruments. I do not believe that the mast has been removed previously. Any information would be helpful.
