lol, nice avatar pic.
My hound (my guess is all 5.2's, although I've only checked a couple) has two holes, and the trap lines mount to the top, while the shrouds mount to the bottom. b/c of the few inches of separation the shrouds and trap lines never touch.
I see how there could be an issue with the leeward trap lines rubbing on the edge of the hound as the mast rotates, although they don't move in relation to it, and have no tension on them.
Thanks for the heads-up. I'll try to test it thoroughly.

OKC, OK

oh, they do indeed. Another problem area is where the trap line swag near the thimble hangs up on the clevis pin to the 5/16" shroud shackle. It is the first 6" that you should provide for a sacrificial cover.

I use a butane powered soldering iron with a hot knife fitting. friend of mine put me onto them. definitely in the favorite toy category!!
That won't work with a pure dyneema or vectran line. They don't melt, they burn. You have to use some type of whipping. My current favorite is electrical shrink tube, works like a charm!

Not true, dyneema melts at 144 degrees Celcius and Vectran at 330 degrees Celcius. Hot knifes do work on these fibers and is the common tool in the shop, it just that a hot knife is not very convenient on the beach. Hood's system provides for a portable way to hot knife the fibers on the beach. We've also used the portable butane torches for various uses, usually 'cause sometimes the wind is blowing hard and lighters and such don't work.
Dave, just curious, have you tried the super glue and a box cutter? It's simple and the glue makes the line much easier to get that clean cut.

Interesting, I couldn't get my Vectran to melt with a torch. It just burned and charred. I have a butane torch with a hot knife and I couldn't get it hot enough at my cabin.
Actually no, I haven't used the super glue technique, I've just been using electrical shrink tube (also sold as 'shrink whipping' at some sailing stores for about 3 times the cost). I take about 2 inches of 3/8" tube (for 3/8" line) and slide it to the spot I want to cut, heat it to shrink (it can shrink 1/2 it original diameter so it puts really good pressure on the rope end) and then cut through the tube. I now have two line ends that are securely whipped and the whipping won't come undone!
Also I cut my lines using one of those ceramic paring knives they sell for kitchen use (don't tell my wife I'm using her good knife). The thing is sharp like crazy and goes through the toughest rope super clean. I'm thinking of getting one just for my gear box it works so good!

Mine does 480 degrees C. seriously like a hot knife through butter!

i'm guessing you have swept spreaders on your 5.2? my 1982 5.2 has straight spreaders and just the 1 mast hound hole for a D-ring shackle that originally carried just 3 eyelets, as each sidestay swage also carried the single crew trap line that was standard back in the day, however about 1983 helm trapping became common it and as extra trap lines were added to the hound it got crowded up there and nacra enlarged the mast hound to accept another hole specifically for trap lines

here's a pic of the single hole mast hound on my 1982 nacra 5.2

Nope, straight spreaders, double holes. 1982.
An owner before the guy I bought it from did some fixes and upgrades. He may have changed the hound.

That's interesting, my 1981 has a hound with 3 holes in it and it looks original.
It also has the shrouds with a trap line swaged in. That confirms my suspician that they are original. Hmm 29 year old shrouds, time for new shrouds.
