Mast base was severly corroded from sitting in water for 31 years. I couldn't pull the cover out. Didn't realize till Mary started this thread that cover did not extend under gooseneck base. Been spending all my time near the mast head. Yesterday I got a 3/4" conduit threaded up from base to mast head, around all the thwartship tubes and fore and aft braces. Today I'm gong to enlarge the hole in the plate on top of the mast and pull some conduit out. Pin it , tie stopper knots in the wires for strain relief, and mount my LED mast head light on it. Will also rivet bottom end of conduit, although it can't move far, Ii suppose it could rattle.
Strategic mistake, I accepted a neighbors offer to split crane costs and use a local vacant lot. If I had paid for my own crane and was driving 50 miles RT to the boat yard, I could take the time to break out the plastic trim strip, grind off the bolts, cut off the gooseneck base and soak the sail track for a week or so to loosen it ,remove it, and then fish for wires out the top all whileI was waiting for replacement parts from Rig Rite I don't feel that I can delay my neighbor that long, or avoid the code complIance geeks.
Oh well, if I keep learning, I guess i'm not just getting older, I'm getting smarter.
