So we’re on an Ericson
27, so our mast is around 35’ tall. Running to our masthead we have triplex wire (to run our trilight (nav + anchor), coax for our VHF antenna
, and the instrumentation cable for our wind sensor
What we’ve done is rivet a 1” PVC conduit on the forward side of the mast, and run all the wiring
through that, then bundled all the cable together before pulling it through. At the top of the mast, there are a couple of zip ties and spiral loom wrapped around the bundle to hold it in place. The conduit also keeps the wires from slapping around inside the mast as the boat
It’s worked fairly well over the past 10 years or so. The only downside is that if we want to replace any of that wiring
, we basically have to drop the mast and work
on it as a unit.
