Hello Fellow sailors, Here are a couple of items that are of interest to Mboaters. 1. The Small Craft Advisor magazine has a discussion going about the M15 & M17 and pointing ability. Those of us that sail one know how well they point. If there's someone that could explain the "why" that would be beneficial to the discussion. This is great , honest magazine and well worth the cost of subscription. http://www.smallcraftadvisor.com/ 2. Doug King has posted a story / article about Jerry M. sailing the Sea of Cortez in a M15. It's good reading and will make you want to go cruising. Doug did a great job setting the article up as it was sent to him in a scanned ( Word ) format and kind of rough around the edges. http://msog.org/ Take care Randy & Greta Watkins M15#194
Hi Randy- Haven't read the discussion in SCA but regarding the 15 and 17, I have some opinions. Aside from the obvious factor of the sailplans, the two main reasons for the excellent windward ability of the 15 and 17 (and also the M-23) are hull design and keel/rudder design. Keeping things simple, the rounded hulls of both these boats keep wetted area low, which means more speed because of less drag, especially upwind because an easily-driven hull will have less leeway. Also, a round hull will be more symmetrical when heeled and therefore the helm will be affected less by heeling. Regarding the keel (I'm including the centerboard here) and rudder, the keel is not at all "hi-tech", but it is more so than most of the competition, and it IS quite effective. Rudders are pretty high-aspect, even when compared to performance boats, and provide a lot of lift to weather when the boat is tuned right. One of my "bibles" thirty-some years ago was Stewart Walker's book PERFORMANCE ADVANCES IN SMALL BOAT RACING, which discusses these things and more, and if you can find a copy you would enjoy it. Reading it kind of makes you want to go out there and mess with your boat. Published in 1969 by Norton, it's probably long out of print. Too bad.

Hi Jerry;
Acting on your advice I bought a copy of the book you recommended and it does make me want to go out and mess around. When the book arrived I randomly flipped it open and it landed on page 60. That page shows a line drawing of a rope traveler used on the Snipe but similar to the one used on the M-15. The difference was this one is adjustable. The text says "...This traveler is shortened in high winds, to pull the boom down but not in." It goes on, but at my keying speed, I'd be typing all night. Have you or anyone else ever set up this kind of arrangement on a 15? Seems like it would be an easy modification to make. Thoughts? Don Haas M15-248

No. I have never made an adjustable traveller on a 15, but I have on other boats that I have raced, like 10's and 12's. On the 15's that I have had, I simply lengthened the traveller as far as possible; just short of "two-blocking" with the becket block on the boom. This lets you center the boom with the least amount of leach tension. If I had a 15 and planned to keep it for awhile, I probably would rig an adjustment. A cam cleat just under one of the holes in the deck would do just fine.
