Re: Mast wiring strain relief

The PVC pipe conduit that Chef2sail recommends is a great idea. I did the same on my boat when I pulled the mast. I have internal halyards and the PVC conduit was the best way to organize the inside of the mast. To relieve stress on the wires, I pulled them up at the top of the mast and passed them through a clear plastic hose filled with polysulfide. This piece of hose is clamped and holds the weight of the wires, not the wires themselves. The junction box is also a good idea if you ever want to pull the mast again. It also allows you to get your voltmeter on the wires to troubleshoot. If you go with all LED lighting up the mast you can go with much thinner wire. Don't forget to change your fuses or breakers to the appropriate size for the new LED bulbs.
