hot-bunking varied based on whether there were riders or extra bodies on board. like midshipman, which is another reason they were usually given somewhat of a hard time. The first candidates are usually non-quals and non-rated and is often a source of some discourse when a non-rated qualified person or a rated non-qual have to be hot racked and the other not. My belief is the qualified person prevails and that is (IMHO) the usual decision. I have seen it go the other way and it caused great discourse. It usually isn't all that bad if you are rotating with someone of similar hygene and rating.
I have seen much animosity when you have let's say a sissy boy two shower a day no-load sonarman, hot racking with a greasy, non-showering, knuckledraggin ape of an a-ganger. But you know what they say. "A bitchin sailor is a happy sailor!"
