Hi, GeorgeGlass.
By itself, no. While the spaceships from the Star Trek universe keep Captain’s and Ship’s Logs, other ships of notable size also keep Ship’s Logs, and the ship’s Captain might also keep a “Captain’s Log” or journal/diary of personal observations he or she doesn’t wish to keep in the main ship’s log.
Seeing the erotica/pornographic bent of this site, I would also assume that the “Captain” just might be well-endowed (or tragically not endowed,) and was (at least trying) to get “busy.”
Cheers!
