THE key question....
Do you need an enclosed head? I don't claim to truly understand women, but I can say two things for sure: women don't like the Three Stooges, and they don't like to pee in front of everyone. If any of your crew are female, they will eventually insist on a having private place to pee on your boat. If you or they don't mind closing up the companionway and hatch and using a portipotti out in the middle of the cabin, then you have a lot of choices of acceptable daysailing boats. However, if you don't want to go through that exercise and want a boat with a head behind a cabin door, there is only one production boat 23 feet or less with this feature: the Oday 23. Find a later model with bow and stern pulpits and a deck anchor locker. A well-made, versatile boat. Not easy to trailer, but great for daysailing and the occasional overnighter. Prices range from 4-6K, depending on condition, location, trailer, etc.
