Bpb, so that you don't get confused, keep in mind there is significant difference between the O'day 22, and the O'day 222.
The 22 is an older style, with the boxier proportioned cabin that is more rounded, with 2 windows per side.
The 222 is newer styling, with more of a swept, angled cabin, and a single smoked window per side angled to follow the design of the house.
Without looking up any performance numbers, I'd suspect that a 22 fractional keel/CB and the 222 (also fractional keel/CB) would be fairly similar. It would be a different story comparing a masthead rig 22…
Well, it's just one number, but the Portsmouth rating for a 22 CB is 104.4, 22 SD is 102.6 and the 222 is 98.3. Huh. So that 222 is quite a bit faster...
