How about selecting a corvette or something of that size, and arrange for it to be crewed from Captain to ship's cat entirely with females ? (there must be some WRNS senior enough in the Seaman branch for Captaincy).
It would be interesting to see how popular service in this ship might prove to be among the feminist sorority, faced with a six-month commission in a steel nunnery. Then we should know what the draw of sea service really was: Life on the Ocean Wave - or Jolly Jack Tar !
My God man, that must surely be against the Geneva Convention on so many counts. I remember back at university, my girlfriend at the time lived in an all female flat - I wouldn't wish that sort of thing on anybody having seen what it was like when you put just 3 of them together for an extended duration.
