Trying out my new roller furling jib and mainsail roller reefing claw.

Image

The reefing claw also serves as part of the lazy jack system, allowing me to drop the main quickly without the sail and spars going everywhere. Very happy with the way it is working.

Need to add some stays though, to maintain proper tension on the jib halyard. The roller furling works OK, but will work more smoothly after adding stays.

Anyone know the "official" offset distance from the mast to the stay d-rings, or a formula for calculating it? I'll add some hypalon glued d-rings through the hull.

Rumbunctious, I'd love to see some pictures of how you are using that reefing claw. Where did you get these items?

I took some pictures of the location of the D rings on my Aerius II that are used for the mast stays.

I measured from the seam that runs through the peak of the coaming. The center of the mast hole is at about 4.5 cm from the seam, and the D ring is back about 23 cm from the seam. So the distance of the D ring back from the Aerius II mast (center) is about 18.5 cm. Also note that on the Aerius II the D ring is sewed in directly above the sponson seam.

BTW, what a gorgeous scene.

Pretty cool rhumbunctious,

I've been thinking of making both of these things but haven't been able to get out of my seat... you are inspiring me. Love the 'Jack stay' idea as well.

So, you roll the sail up by pulling the gooseneck off the mast, and then you just slide the reefing claw down over the sail from the end of the boom?

What did you use for the little rubber 'grabbers'?

No guide for the roller, just a spool?

Pretty sure you could sew the D rings easily with a hand awl if you wanted them up on the deck. Quite possible the hull position offers better support though.

Great stuff, thanks for the pics and inspiration.

Really creative stuff, thanks for pioneering and sharing. That is a really nice rig. Put it together with Dennis' platform idea and you can sail in just about anything.
As for the stays, I would highly recommend using the D-ring that is attached to the bracket. The design is sound, the force transmitted to the hull in heavy winds can be significant and I have been thankful, on more than one occasion, that I had the frame to take the strain. I would be concerned to rely on the hull alone, even with backing, to handle this. Ironically, I went for a sail this weekend in gusty, 15-20 mph wind and watched the windward stay pull on the D-ring causing it to deflect upwards by maybe an inch, and that is with the support of the bracket attached to the gunwale.
Just my $.02

I believe that Mark Eckhardt (i.e. Long Haul) recommends gluing hypalon patches on with the D-rings in them-- he sells them, or can add them if he's doign some work on your hull (admittedly the latter is not likely from Finland).

That's a handsome piece of woodworking. Simple and clean. Thanks for the picture and sizes.
