Also look at the MacGregor 36 cat. It supposedly sleeps eight with a little Mazzola oil, but 4 very comfortably. Mary (Wells) and I had one and raced it all the time. Its Portsmouth Number was the same as a Hobie 18.
Pretty hot boat. OUr strongest competitor was a Condor 40. It was faster upwind and we were faster downwind. That is until I replaced the daggerboard (the earlier models had single board and it worked fine) with a much longer (deeper) Formula 40 board and then we took it in all directions.

We used a 9.9 Yamaha 4stroke and it would motor around 8-9 mph.

Prices can be under 20k, but they are a rare find.

Visit the Forum on bigger multis, or better yet, use this Forums "Search" and simply ask for MacGregor and have it search all Forums.
Good luck,
Rick
