'sport' monohulls are quite popular like the Henderson 21 (SRMAX). I think I would really enjoy a 'sport' trimaran in the 20' range with enough under deck storage for some gear and a cooler but with plenty of performance to go. That would be a distance race machine! How about a scaled down ORMA 60? Oooooo. Yeah, I know...try to do that under $20k - huh.
