wire slapping inside mast

Have a cal 29 - halyards are external however the VHF cable and the wiring for the masthead light and steaming light run up inside the mast ( deck stepped) - the slapping can be noisy when rolling at anchor or dock - any easy fixes or way to reduce noise ?- my fix so far - ear plugs at night if it gets bothersome.

Re: wire slapping inside mast

I once tried using a series of three zip ties around the wire, positioned every few feet so that the tails would stick out like ribs on an umbrella. Didn't work :-)

Re: wire slapping inside mast

Hmm. I'm just about to run wires up my mast for a Anchor light and a Windex light. Currently I only have four halyards inside the mast. I've been a little worried about the noise.

Now I'm more worried.

Re: wire slapping inside mast

Zip ties didn't work for me, too easy for them to get rotated when pulling the cable. I used small 1 inch by 1 inch foam strips zip tied to the wires every 2-3 feet, has worked well for me.

Re: wire slapping inside mast

The offered solutions may work but I think that they all require dropping the mast...probably not what the OP meant by 'easy fix'.

Re: wire slapping inside mast

Yes, you 100% need to drop the mast.

Unless you want to climb the mast and try drilling a bunch of holes in the mast every few feet and stuffing foam or perhaps spraying foam (not likely to work). Might get away with one every 6-8 feet but it's still a really dumb idea.

Wires/ halyards in a conduit work

Foam noodles or foam deteriorate over time and create a fine particle mess

Then you have to affix the conduit to the inside of the mast, no? That seems challenging as well.

Re: wire slapping inside mast

No. No.. NO! don't spray foam in the mast. Some PO of my last boat did and it took me several days in the boatyard to chip it out (BBQ fork on the end of 20' of PVC pipe).
