Tiki 21 is a nice boat, comfortable but not fast. The Reynolds 21 is pretty fast and has storage inside (you could sleep there if needed to. (there is one for sale at our club, young fellow single hand all the time) I have a Stiletto 27, rates about the same as a H16 or better. I've put 10 people with plenty of room to spare (not to race though). Fun to sleep on or in. If you want more room than that you'll need to go to a leaner, but you'll never do 15 knots on one of those.
