AFAICR we never had a problem with unprofessional conduct between student and instructor at Nav School.
Until we had female studes that is
.
Joking aside it was so new and no one transgressed (initially anyway) that there were no rules. There was however mutterings about one old, sallow and balding (but not fat) instructor and one particularly notable student but, again as far as I can recall, nothing ever came out if you forgive the pun. He was the course commander.
