Madsu had no steaming or anchor light, and last season I got by with a portable LED that I’d hoist when needed. It worked ok but wasn’t great. When I redid the electrical system last month I installed enough circuits to incude a steaming light and masthead anchor light.
I debated whether it was worth the trouble of running conduit up the mast – but figure if I don’t I’ll be regretting it the first night an anchor as the wires clang away inside the mast.
I opted for 3/4 inch PVC conduit that will have more than enough room for the 3 wires I need to run – plus room for VHF coaxial should I decide to add a masthead antennae later. I got a laugh when I saw the label on the conduit – C22 for a C22. Nice.
Of course the conduit has to be secured, or it will bang around. This is easier said than done.
The conduit is riveted in place using a technique I read about online somewhere. Starting at the base of the mast I was able to hold the conduit in place while I drilled a hole in the mast and the conduit and popped in a rivet.
From there it’s a matter of drilling a hole 6 inches or so along, using a small Allen key to hook the conduit through the hole (in order to hold it in place), then drill another hole a further six inches along and pop a rivet in. After I was done, I filled all the extra holes and was ready to etch, condition and prime.
The mast got it’s first layer of base coat this afternoon – the boom got its 3rd and final coat of base. I should be able to get a couple more coats of base on the mast tomorrow, then on to the topcoat in a couple of days, assuming the weather holds.
