When I started my career, I loaded up the damage control with a bunch of skillesss sailors, picking the ones who had high stat values in different areas. This way I have extra crew, and depending on where they may be needed elsewhere, there is someone with good stats to swap with. Right now I am on my 11th patrol and those guys are all NCO's with different skills to match their stats. Its sort of like a reserve for the rest of the ship. At the same time, their mechanical ability goes up, making them good damage control guys
