Hi, I have a 26'' boat with a swing keel. I have just gutted it out & one of the first things I was going to do was the wiring. I purchased & read Don Casey''s book on wiring a sailboat.
Here is the problem(s).
1. He says to ground your house batteries to the engine so the ground will be in contact with the water through the propeller shaft. I have an outboard that when not in use, does not touch the water.
2. He says for lightning protection you should ground your mast to the keel with a #4 wire. My keel is a swing keel that has the pivot point outside the boat under the waterline, so attaching to the keel is out of the question.
Any advise would be helpfull.
Thanks, Larry C
