Midwatch BS Sessions

Back when I was Eng, I always had to go along with the idea that the best use of your time on the midwatch was for watchsection training -- everyone remembers the EOOW or DOOW monotonously reading from procedures to his captive audience. From the safe distance of retirement, however, I can admit that I always hated that. I much preferred the free-wheeling discussions that would often break out -- whether it was debating about religion and the nature of life, or coming up with "name all things on the boat that have nicknames that are animals", like "white rat". There was something about being in the middle of the ocean, under several hundred feet of water, that seemed to be conducive to deep conversation.

What were your favorite midwatch discussion topics?
