Cruised to Mexico
and the Sea of Cortez
in the mid 80's with two couples; one couple in a Falmouth 22 and one couple in a Dana 24. Those boats really have all you need and are seaworthy
to a fault. Both were as fast as our 30 footer.... actually the Dana a touch faster. Both had similar accomodation as our 30 footer. (really until you get up to where you have two heads and two double berths, the main difference is floor space between the fixtures!) You take what you need, and encumber yourself a lot less!
