One last item I’d like to have on me if I’m in the water would be an LED flare or very bright LED torch. Saying that, all this electronic kit has to be stowed somewhere and I’d rather not be walking around the deck looking like a modern police officer with things dangling from my waist ready to get snagged by any one of a hundred bits of deck gear around me. Probably the best solution is to wear a head torch with built-in strobe at night and in fog. I know this sounds a little excessive, but since testing a bunch of them some time ago and found some that are so light and comfortable that I find it easy to forget I’m wearing one. During the day I keep it inside the companionway, next to my diver’s knife.
