When running at night, its a good idea to have some means to quickly find a crewman that accidently falls overboard. Most of the guys I fish with all wear some sort of floatsuit for the ride out (keep in mind we fish aboard an Intrepid CC so it can get a little wet and cool on the ride out) with either glow sticks or a water activated strobe attached to the suit. While there's no guarantee that the sticks or strobe will stay attached on impact, it's just an added "comfort" measure.
