cottage park?I like the focus on addition vs transition. We added a Snipe fleet to our club that drew in new members without interfering too much with the Star fleet (a couple of us sail in both), which has grown in that time as well. More importantly, the Snipe fleet drew new blood into the class, which limited the impact on the other local Snipe fleet. We offered open water vs. super-shifty flat water nearby, so it's a different offering.
In our case, we had critical mass around Snipes, but that very easily could've been an M15 with the right initial, critical mass. 20ish years ago, however, someone tried to to the same with the V15 and it sputtered out before it ever got started. I even briefly considered adding a V15 to my program to sail there (I was on the lake at the time), but decided it was simply not a boat I wanted to own for a host of reasons. The M15 does look interesting and, if there's a local fleet, I could imagine at least checking it out. But like fleets everywhere, it takes a very strong personality or two to make things happen.
At least the M15 has a chine.
