I have a 1980 C27. Bought the boat in late August, 2011. Mast is currently up. I will be unsteping in another month or so to check standing rigging and install a furler and want to know what kind of a mast wiring cable connection I will be seeing when the mast gets pulled up. Will be doing this with the marina's crane and so don't want to be trying to figure out how to disconnct while they wait for me. Anyone know what kind of connection is there at the bottom of the mast for a 1980 C27 and how to unconnect it? Thanks for the info.
