I wasn't so much suggesting that but wondering how the high end manufacturers handled this issue. I have no idea if everything inside my mast is original but the best I can tell from the wires coming out the bottom it probably is. Does anyone have any insight into the internal setup on the Selden maybe there's just a barrier at deck level to divert what water sneaks in to keep it out of the bilge.
I don't mean to hijack but there may be some design features here that can help others.

Ditto on the 5200. I think it's in Casey's book, too. I used it and it's held up fine. I suggest using an oversized pvc conduit and run a couple messenger lines through it so you can easily add wires later.
If you assemble the conduit when the mast is down, brace it so it won't roll, and run a generous bead of the adhesive along the top. Slide it into your (horizontal) mast, then roll it 180 and let it sit there till the glue sets up. In my case, I drilled and pop-riveted every few feet for good measure. After the glue sets, it will hold the conduit while you drill.
I tried the zip-tie spider idea earlier and the results weren't satisfactory.
Incidentally, Liquid Nails is also a polyurethane adhesive, as is 5200.

Re: Ideas on securing wires inside mast?

I have to wonder how someone like Selden balances all the in-mast items, at full dress I will have 6 internal halyards and all that wiring. I don't know what the inside of my mast looks like but everything is fine right now. I would think a separate conduit for mid-mast and full height would be the way to handle the break you would need with one conduit. Also I'm keel stepped and looking in while rigging a spin block showed some expanded type foam dam at deck level, the wiring of course keeps going and the Halyards exit at deck level. One reason I bought my Boat was the quality mast section and looking at others surely considerable more thought was given to its construction inside and out. So one day I will find out but there may be some drawings available online although I haven't researched that. I do like the noodle idea by the way.

Re: Ideas on securing wires inside mast?

I just did this job yesterday.
I had a few things going for me though.
I have 3/4" foam lining the inside of my mast that goes up beyond the steaming light.
This foam was put there for four reasons.
One, to quiet the halyards.
Two, to hold the wires still as the wires are routed up between the mast and the foam.
Three, to help prevent shafing of the wiring.
Four, it helps to reduce condensation on the mast.
This has worked well for over 30 years and if it weren't for the upgrades I wanted to do it would probably have lasted for many more.
The advantage I had was I was able to insert the 1" sched 21 pvc up the mast in between the mast and foam, leaving the original foam in place.
I cut the end of the pvc on an angle so it would pass up the mast easier. With the foam going almost 3/4's of the way up the mast I did not have to rivet it all the way down. I riveted it about 1/3 of the way down and let the foam hold the rest of the conduit still. I did add a few rivets at the base of the mast and above and below the steaming light.
I also extended the conduit so it is flush with the bottom of my mast. The conduit sits on the mast step rather than relying on the rivets to take the weight. I used 90 degree pvc "T"'s for wire access at the steaming light and where the wires exit the mast. This gives me a full 1" access hole without compromising the conduit's structure.
Took me longer to measure, cut and glue the pieces together than it did to push it all the way up the mast and secure it with a few rivets.
I now have a new anchor light and wire, new vhf antenna and coax, new wires for my wind machine, new wires for my steaming light and deck lights and room for a radar data cable in the future.
My new genoa halyard will be tricky to get right. I cannot have it going around my Nav-tang cross bolts. It will need a clear run through the mast. Wire halyards can cut through Nav-tang cross bolts and bring down your mast.
When I am done I will have 6 new internal halyards, all new mast wiring and new "USCG" approved LED's.
All of my outside lights are now USCG approved LED's.
I have a thread going about this project. I have one more day of rigging left to do and then my mast is ready to go back in the boat.
I'm taking pictures and I will post them.

Good luck,
Peter

Large plastic zip ties.

At regular intervals along the wires fed through the mast, attach a zip tie, leaving the tail. Orient the tail at different directions at each interval. When pulled through the mast, the zip ties will act as "springs" keeping the cables pressed along the side of the mast, preventing them swinging back and forth and making noise.

Cheap. Light. Lasts forever. Easy to do. Works well for me.

Re: Ideas on securing wires inside mast?

I'm leaning real hard toward the Fun-Noodle deal--looks like it could solve an age-old problem very inexpensively.

Thanks everyone,

Gary

Hi Gary,
I too have a Morgan OI33. I too had a banging mast that was a nightmare...the previous owners clearly never left the dock! So after considering everything we also used swim noodles and they have done the trick for 5 years now.

Mast was unstepped of course. We put in as many as would go in. The trick is getting them high enough in the mast. I believe we utilized messenger cord to pull up the noodles, taping them together into one long noodle. We got a couple of these multi-noodles probably 2/3 up the mast, which is plenty for this issue. We also pushed a few multi-noodles as high as we could. The most annoying obstacle is the tips of screws from stuff mounted on the mast, grabbing the foam noodles. Anyway, it worked. Good duct tape and Walmart swim noodles. Very cheap, and I don't see why they'd fall apart, at least not for many years. No noise now.

And if you get dis-masted in a blow your mast will now float!! ..just joking.

I say either step or unstep the mast.

I agree. Dismasting should never be mentioned near your boat, just like sinking, or holing, or we ran out of tequila.
