Halyard Hound Mounting for Jib Cover

Post by dca81 »

I have a 2004 :macm: . I just ordered a jib cover for my CDI furler. I need to mount a new mast hound above the current one for the halyard to raise the cover. How far above the current one should I go?
Thx

I do the same, 95 :macx: . Works well. Although I typically don't put the sock on as I mainly day trailer / sail.

I would mount it 18" above the headstay, so it can be used as a spinnaker halyard too. If you're going to use the same parts, and do the same work, might as well gain the benefits.

Ditto.

For the first 6 years the block for the sock halyard was attached to the same hound as the forestay. I will admit to occasional issues with my halyard wrapping up in the genoa as I furled it...not a significant issue but an occasional PITA.

But this year I bought a spinnaker and added a second hound 18" above the stock one. I mounted the block for the genoa sock on this new hound. Now the sock halyard (which doubles as a kinda/sorta/psuedo back-up forestay) is well clear of the genoa when furling and I have 0 issues with this anymore.

Adding the second hound was very easy.

Good Luck.

Cheers,
Jim

Jim and Tanzler, thanks for the response. BWY also recommended approximately 18" so it could double as a Forestay for a Spinnaker. Currently I am still trying to become minimally proficient with just a standard jib and not thinking of a spinnaker. !8" just seemed like it may be to high and result in a poor angle for raising the cover. Thanks again.

Agree with captronr. I have a 26M and used this configuration for 6 years.

Here's a sketch of the geometry of an :macx: with a 28 ft mast (cyan), forestay starting 4 ft from the top of the mast and terminating 10 ft forward and 1 ft down (white), and a spinnaker halyard (magenta) run to the bottom, and to near the top. At the top it's only about a 10 degree angle with the forestay. Being that any sun cover has to start where the sail is widest when rolled (the bottom), it will be a bit baggy at the top, where the rolled sail is thinnest.

I'd guess there wouldn't be any problem raising the sun cover with a spinnaker halyard. Just FYI.

Oh, and the :macm: mast is 2 ft taller, and I'd assume the forestay is also terminated 2 ft higher, making the angle between the mast and forestay even smaller.

Try the jib halyard for a while before adding something specifically for the sun cover. But remember that if you add a spinnaker halyard, it can double as a backup forestay without fouling the jib or genoa, and you'll have gained experience by then and may wish to actually fly an asymmetric.

Be careful of assuming, you could be wrong, in this case you are. The forestay hound on the M is mounted exactly 6 feet down from the mast head thereby maintaining the same fore triangle as the X and being able to use the same jib or genoa on either rig. I have a 26X jib on my M.
I also have a spinnaker hound mounted 18" higher and I also have a small hound like fixture mounted just above the forestay for both the jib halyard and sock halyard. I had a severe case of halyard wrap on my Schaefer CF700 snapfurler and had to install a halyard lock fixture just below the forestay to prevent the halyard from wrapping so then I added a fixture just above it for hoisting the halyard, it is riveted on.

Fair enough, but my erroneous assumption was in support of the geometry being very good for raising a jib cover even with the angles experienced when the halyard block is 24 ft above the base of the mast. Better if it's higher still (smaller angle between the forestay and the mast), assuming the forestay terminates in the same place. As it is, since the halyard block is in the same location relative to the deck, the geometry looks pretty good for pulling a cover all the way up.

Not a fan of the sock. I moved to sunbrella on my jib - life is better!

Which means I have a sock sitting around gathering dust. Let me know if you would like to enjoy the misery that is the "sock". :)
