Wiring inside the mast

[orion1]

We have an older mast without the neat extrusions designed to accomidate a PVC tube channel. The wires are just loose in there and make a terrible noise while at anchor. We had the same problem with our last boat and installed a PVC tube with pop rivets. What a job.

Has anyone heard of using those small tubes designed to insullate plumbing in the cold months outside to just run up the already installed wires.

I spoke to someone at the yard where we are hauled, who was doing a rewiring job on a newer mast, who indicated that it seemed to him that it would work and probably be a major improvement.

I was thinking of trying it by taping the six foot sections together as the were pushed up to the top. I think I have room for two tubes, one to the masthead and a second to the steaming light height.

Sounds like a neat approach - IF the friction will allow you to push the tubes up far enough. Could be like trying to push a rope....

No first hand knowledge, but I've been told others have done that, with good results.

Bundle the in-mast wires with wire ties (Ty-Wraps), with the tails left long. The tails should be oriented at about 120 degree offsets, so that the long tails contact the inside of the mast at varying positions around it’s diameter.
The Ty-Wrap tails help keep the wiring centred in the mast, with enough flexibility that internal halyards are not adversely affected.

I like Gord May's solution but it does require take the wire out to do it. Not sure if the pushed on conduit solution will work but I would try it on my own boat. What about taking a fish tape and putting it down the mast to help the conduit up?
