Ray, a lot used to be made of how many berths you could cram in to a small sailing cruiser as a selling point. The Spring claimed six but that would have been very crowded indeed. My Jaguar claimed five. But the most I ever had aboard was three, one in the forepeak, one aft under the starboard cockpit seat while I, as owner & captain, sprawled out on the saloon double and very nice it was too!
Normally on a trip it would just be two of us with the forepeak used to store gear. The boat felt really roomy under those conditions.
My lift keel Jaguar 21 was definitely two only.
