Re: 30 vs 33
I've owned a 30 and sailed over 30 years on a friend's 33.
Both are sweet boats.
I preferred the 30, the reason I bought one. The primary reason is that the 30 has a more useable interior. The 33 has a sloping foredeck that removes the headroom forward of the mast, and the head is open to the v bearth. Having cruised both boats, I consider the 30 to be more liveable.
Secondly, over years of PHRF racing the several 30s in the fleet would consistently beat the several 33s, period, boat for boat. Not always, but regularly. Occasionally when the class breaks had the 33's starting 10 minutes earlier, on a breezy day the 30s would still beat them.
Certified...in several regards...
