Pictures?: H37C Staysail Furler

[coleman]

I am considering going to a boomless, or a loose footed club, staysail with roller furling. Staysail outhaul is getting a little sticky on the factory boom and any excuse is good for a project

I know this must have been done; several times... Searches are coming up weak as it seems most of the other boats with furling staysails don't have the gooseneck on the inner forestay. Looks like to retain the existing boom for self tacking I'd need to raise the tack of the staysail quite a bit to fit the furler drum. I'm not sure how that all measures out or if I'll need to go boomless (which I'm considering strongly at any rate).

Pictures, descriptions, experiences would be helpful while I start to consider design.

Check out someone like Hanse. The have them from the factory.

For my money, it is an either/or choice: club-footed staysail using existing boom & hanks or loose-footed with roller furling. Anything else gets too complicated and unreliable.

Piece of cake to disassemble the staysail boom and service the outhaul though...and cheap too!

Ed Allen's 1984 had factory furling for the staysail. And it incorporated the boom. If he sees this he might be able to explain it. Now that he sails a C-40 he doesn't get on here much. You could still find him and do a PM or e-mail. I do have one picture, not Ed's boat.

I went with a loose foot on my lighter stay sail, but it's still hank on. It also has battens for more sail area so I couldn't go to a furler. I like the bigger sail alot haven't used the heavy sail all year.

Forgot my point. If I went to a furler I would go over lapping without the boom. Down side not self tacking and added cost of sheet tracks on the coach roof. Upside the added power would be nice on light air days.

I found a good resource at RigRite regarding typical installations of jib boom goosenecks...
http://www.rigrite.com/Spars/SparParts/Jib_Boom_Pedestals.html

I haven't seen any roller furling examples where the original "jib gooseneck slide" option, common on the H37C, is retained. Models of sailboats I am finding use pedestals to get the furler closer to the deck (at or below gooseneck height).

The Hoyt boom seems like a neat idea but I'd have to see if that made any financial sense and could be a proper design. The final installed geometry would require more pre-installation design considerations due to the fixed sweep of the boom once all is bolted in and finished.

This pedestal (below) looks like the one used on that Hunter. According to RigRite, this was made by Forespar (which is now pushing for the Hoyt boom). I'll have to see if this is what Hunter used since these are relatively easy to find used from a wide range of boats. But, it sure would be nice not to poke more holes in the deck for this (which is why boomless is still a strong option for me)...

Furler for staysail
I had the 1984 H37C with furling staysail. I used all of the factory components and shifted the Crusing Design furler that was on the Yankee, shortened it and added it above the Goose neck. It worked great. The end of the boom needed a topping lift, but that was the only modification. The sheet became the outhaul and I added a furling line. Took this set up to Bermuda twice, sailed and reefed in 45 KTS, sailing with staysail and tripple reefed main in complete control. An absolutely fantastic set up. I am so in love with the staysail that I am adding one to my C400. I think you can still PM me for additional info. Alan J Formerly a very happy H37C owner.

Alan Johnson gave me permission to post this picture he sent me of his previously owned H37C. This photo shows the CDI furler resting atop of the gooseneck slide.

It's unsecured and is free to move along the stay should any force act to lift the system. This works because the CDI furler has it's own halyard; all luff tension is reacted by the luff track instead of the mast, so it does not have any reason to lift from the gooseneck. In a typical installation the turnbuckle is integral to the furler unit and there would be no chance for the sail to lift even if forced, but Alan says this worked fine for him even in bad weather. No modifications to the inner forestay means it would be very simple to return the hanked sail if preferred.

Thanks to Alan for the photo and the description of his setup.

Removed staysail, thinking furled

I just made the staysail removable with one of quick releases made by Johnson. Like to be able to have a staysail, possibly without a boom and possibly with a furled? Ideas

I guess I didn't look hard enough in the H37C photos for this site... Just came across this.

Here's another thing to think about, if you go with a boom, depending upon what dinghy you have, but when I slapped mine up there on the front (seeing that this is the only proper place to stow it when going out in big water because of it not fitting down below), I had to raise the boom so it would swing freely over the top of the dink's hull. It wasn't hard, it required a longer penant, that's it. The sail was originally cut by JSI to be smaller then needed, so I didn't have to cut the sail. I like the idea of a boom, regardless if it's loose footed or has a shelf. Hanks are nice for flaking the sail onto the boom, a track would give it better shape when up, but if you go with a track, might as well go with a CDI or similar with internal halyard. Sailor's Exchange in St.Augustine had a CDI roller furler in their store, looked very similar to the one I have on the 37C, and it looked like it was in great shape.
