As has been said by others, you can compensate by going larger with the same accomodation, but that has problems of berthing and handling short handed as well. IMHO 43 ft is the max I would consider for a crew of two + occassional visitors.
Unless, of course, you have a rig designed for easy handling, such as a wingsail rig based on modifications to the junk rig
to make it more close-winded and aerodynamic. I agree that the standard marconi sloop
rig was designed to give the maximum of difficulty and entertainment to large crews of athletic young men
striving to race
around a few buoys on sunny summer afternoons, after which they would hit the showers and yacht club bar.
