Not only did I pack enough clothes so I can get away with one wash on board (you must sacrifice a shower for a wash, and you only get a shower every other day), I packed a BUNCH of electronics-
computer, PDA (with lots of ebooks), MP3 player, GPS, VHF/UHF ham radio transceiver (for satellite operation), digital voice recorder (backup for MP3 player and for recording satellite contacts), pocket shortwave radio, active headphones, and camera, as well as batteries and chargers for all of the above.
I also brought along power distribution bits, since I knew there are about 1 1/2 outlets per cabin.
The crew all carry, on their belts, knives and spikes, at a minimum- most carry flashlights, and a few have multi-tools, too. They range from fancy store-bought rigs (one person), to repurposed kitchen knives and railway spikes. I have mine, too- a small flashlight and a fancy Leatherman.
We all have lanyards on everything, so we won't drop them over the side or on someone's head while aloft. Many of the carrying pouches are made by the carrier of leather or sailcloth, and one decky from Scotland has a pocket for a fan, since it's already warm here for her.
The 12-4 watch is a bit hard, but since we changed timnes zones by TWO hours when we cast off, it's not as bad as it might be.
