Cost is the key
I debated for quite a while between the 290 (was the last on the lot) and 326. Being tall (6'4"), I was biased to bigger, but settled on the 290 because it was considerably less expensive and was almost the same.Admittedly, I'm cramped for headroom, but I've had as many as ten people aboard sailing to a raft-up and managed each time. I spent 3 weeks cruising both Florida Coasts and was never uncomfortable.Yeah, I'd like a 426 or 456, but that's still a few years away.BTW, the 290/306 is a pocket rocket once you realize it sails more like a Hobie or Prindle than a conventional rig. Blade the jib, pull in the main and point high. In good wind (15kn - 20kn), I've chased down a Benetau 352, and in a high-wind race (20kn at start, 30kn at finish), we kept up with a Tartan 41. Some very concerned skippers on the other boats. Lost ground on the downwind run though.
