I was going a little crazy trying to remember all of the things we’re wiring into the mast and what kind of wire they needed so I drew it up.
Included in this simple not to scale drawing (my spreaders are not mid-mast) are the wires for the NMEA 2000 instrument, all 2 wire and 3 wire pulls for lights and the PA horn as well as the COAX which is going to be run in the mast. These were run in the mast hanging free and wrapped in foam. As part of the refit we will run PVC conduit inside the mast for the wiring.
