[Public-List] Getting mast wires into the boat?

[Bill Wallace]

I use the slightly larger than single wire sized cable clam to get 4 wires - a triplex, two duplex and a round vhf wire so that I can disconnect everything in the winter when the mast gets removed.  It seems pretty dry.  I'd probably freeze it though for the initial drilling - and it is really painful getting the wires through initially, as at least for me it was a fairly small hole I used.  You could probably wrap the wire with butyl tape to ensure a totally watertight pass through the rubber stopper.  I'm planning on redoing it this winter as the VHF cable is spliced twice and I'd like a better set of disconnects inside the boat and at the top of the mast to allow me to remove the wind instruments cleanly every winter.  The wires also bang inside the mast so I plan on wrapping several sets of 3 cable ties to keep the wires centered and prevent banging (every 3' roughly you wrap 3 cable ties with the ends at 120 degrees to each other and preventing
 the cable from slamming against the wall of the mast.)

Bill.

Hi everyone,

I'm wondering what everyone else has set up to get the wires from the mast
into the boat?

I have a setup on #116 where someone has drilled a hole through the mast
step plate, through the mast beam and it comes out just inside in the
v-berth just forward of the beam. A stainless tube was inserted and the
wires from the mast are run through this tube, into the boat cabin to a
connections box. It's a clean setup from the outside, however we've
discovered that unless you get a good drip loop in the wires at the mast
base water can flow down into cabin and drip on the floor. And, the sll the
wires into the tube is a tight fit.

I'm about to remove my mast beam completely, and laminate a new one out of
sapele (or perhaps white oak). I think I'd like find a different solution
for the wires to exit the mast through a hole, then into the cabin top via
some fitting of some sort.

I've used the Cable Clam type fittings with success for single round
cables:

I wonder how those would work for multiple wires and duplex covered wires?

What do you all do??

I hope everyone is having a great season.  We decided to skip putting our
boat in the water to get some house and boat projects done, can't wait
until next season already.
