Changing Coax in the mast.

I'm hoping someone has done this or has some tips that may help. I am changing coax cable that runs inside my mast. I'm doing it w the stick up and will be using a bosuns's seat. The plan is to use a thin rope at the top, connected to the cable and then to haul it out at the base and then pull the new cable through. This will be done w the boat on the hard...but I gotta do it.

When we did a similar job on my boat we found that the in-mast wires were all cable tied together every 600mm or so all the way down the mast. Rigger wound up having to pull the entire cable bundle out and lower it to the deck, then pull it back up so we could re-pull the wires in using messengers.

I hope your experience is more positive :-)

If a dirty bottom slows you down what do you think it does to your boat

I replaced the coax cable in the mast with a larger diameter cable some years ago and if memory serves me correct someone was at the top of mast with me at the bottom pulling on the cable. (keel steped mast) I think that we taped the new cable to the old and let gravity take everything down just requiring a careful pull when the new cable exits the mast. We could have used a small line and let it down that way too. Thinking about it more I think the small line was used since we could secure the new cable better to the thin line vs securing it directly to the old cable plus the thin line helped pass the new cable through the small diameter hole in the bottom of the mast. The boat was in the water BTW.

Joe-

Do not go up the stick on the hard. It is really dangerous, and if the boat starts to tip, it isn't going to stop, and you're going get really seriously injured. Either hire a bucket truck or wait until you're on the water.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

That is the tip that helps, that is the #1 tip, read that tip, it is the one that must be understood first.

I got other ideas but they do not matter, that is the one, that one there, that tip is thee tip.

OK, I got it. I'll do it on the water. I don't want to be a human domino or bug on a windshield. Thanks!

no no no..I gots the answer man!!! Did mine last summer aand stuck everywhere tryin to thread my new cables...even with the mastdown...until an old man came with his hoover and guess what...2 secs. later and theres my sailing thread with a screw on the head right out the bottom..I gave him a monte cristo#4 for his trouble.I called him a geniuos afetr my weekend of cussing ...So climb your mast,forget the warnings from the nannys and drop that nut. Hook up your hoover end and suck it down..or have someone on the bottom so you dont have to climb 2x..oh,the hooror..of course sew the ends together(coax and sailing thread and tape the connection...must use strong thread!!

ps. Use a very light weight on the end,I think I just used a litle screw..good to test it out horizontals as your limited when you get crowed.oh,just rig a good attachment at the bottom to reduce air escape but dont think it matters. You got gravity on your side ,too. My old mast was on the hard and couldnt keep that nut fom gettin sucked!!!!
