Post subject:  Three Sails, Two Snuffing Bags
It's been about a year now that I have settled into this current configuration of sails and rigging. Thought I would share in case someone else was going down the same road.

The boat has two snuffing bags, one on each side. (Tony Stott saw this coming last year. :lol:) One bag for the spin and on for the jib. There are metal quick releases on the head and Tack with a plastic ball quick release on the clew (for safety). Using the original Hobie spin rig, and the quick releases, allows me to switch from sail to sail easily and in less than a minute. I like this arraignment for the jib better than past rigging because it allows me to fine tune the tension on all three points of the jib's sail, just like the spinnaker. This turns out to be important on the jib when maximizing trim. This and the position of the jib fairleads allow me to choose between the pointing and power trims of the jib. Here is what it looks like while sailing.

Looking good. Have you done any "speed tests" to see if you are doing better (pointing, speed, vmg) with part furled main and full jib or unfurled main and no jib? I know you can't put enough tension on the jib luff to get it back to centerline, but it seemed to be drawing well. You might want to try a 2:1 jib halyard.

No speed tests with partially furled main for comparison. I'll have to do that comparison. Only tests so far have been full sai.I CAN tension the jib halyard to bring the luff to the centerline but I find the if I relax the luff ever so lightly, I get better performance from the sail. I was told the sail was cut in such a way as to fly with a mildly open luff. When I shape it for pointing, I tighten and center the luff while tightening up the foot. Hobie's single loop spinnaker rigging let's me make just about every imaginable jib shape possible.

I like the control of the heeling moment and balance of the boat that I get with a jib and half furled main sail in higher winds. I do notice with my AI2 that a half furled main begins to loose it's ideal shape because the clew loses some of its downward tension. I resolve this with a bungee that acts like a boom vang even though we don't have a boom. I'll post pics and maybe some video of this later. Everyone can benefit from this trick whether you have extra sails or not.

I have noticed subjectively that I am now able to point just about as high as the main alone but I don't believe I point higher. I think our AI2's already appears to point higher than our AI1s did. I'm guessing it's due to the better sail shape of the main (longer/thicker battens) and the bigger daggerboard.

That looks awesome Greg, like Hobie sold it like that! I couldn't easily see from the pics, but as it sounds like you use the one set of sheets, how do you set up the different leads for them? I see you have the jib sheet fairlead at the front crossbar. I assume you have a simple hook there with tension on the sheet set at the cleat on the rear crossbar.

I attached a large air conditioning duct zip tie at the ideal sheeting angle on the crossbar as my fairlead. The right failrlead is white in this video and I am using a small black rope as a fairlead on the left side. I will replace both with black AC zip ties for aesthetics. Then I used Hobies nylon rope clip and run the sheet through the hole. This allows me to be able to attach and unattach the clip/sheet as needed to the fairlead.

I attach the clip to the zip tie when flying the jib and unattach it when flying the spinnaker. This assures proper sheeting angles since they are different between the sails. The clips are never removed from the sheet and can't fall off or get in the way because they are trapped between the clew and the spinnaker sheet cleat.
