Can't say much about the specs....those should be well known. Who is the sailmaker? I purchased one for my M17, and have concluded that it has minimal use....at least for me. I single hand most of the time, so setting one up takes some time. I don't race, so the need for speed isn't an issue with me. Moving at all in light air was and still is my motivation for having the sail. The AS was intended for very light air....less than 5 knots. Above that, and I fly my 155% genny, which is more versatile on all points of sail. The AS will work with any hint of breeze, but what I found is that as the boat speed picks up....the apparent wind shifts forward....and if the breeze lets up any the sail will collapse (boat is still moving so apparent wind shifts dead forward). So I fall off to fill the sail again.....boat speed picks up, sail collapses...I fall off, etc. So what I found was the only point of sail I could use it in was broad reaching to almost downwind...at least in very light air. If you are sailing on a beam reach or any point higher and the wind does pick up, you are in for some excitement. I'd say that 90% of the time I've used the thing there have been incidents where I've gone from 2 knots to 5 knots plus and hanging on in less time than it takes to tell about it. If I was looking at something like a 5 mile or more passage downwind in very light air, that would be the sail. I'd have to be going far enough to make it worth the effort to drag it out and set it up. It's also affected by boat chop. The waves will rock the boat, shaking the wind right out of the thing, making it difficult to set and to keep set. But that's true of any sail and always a problem in very light air. Not trying to discourage you, just relating some experience to help with expectations. Bill Riker has that nice Kern sail for his M15 and may have a different experience. It seems to me that relative to the boat, his sail is smaller than mine. I also know that when he puts it up, he is a hard guy to keep up with. Howard On 10/31/05 4:44 PM, "John L.

Hi, I'm interested in getting an asymmetrical spinnaker for my M-15. A sailmaker familiar with Montgomerys recommended one with dimensions of 16' luff, 14.5' leech, and 8' girth, made of 0.75 ounce nylon. Total sail area would be about 108 square feet. Does this sound about right?
