Yesterday, as I sat in the smoking lounge conducting an appraisal with one of my reports, the ship went dark and silent. I jumped up, looked out a porthole and saw we were slowing. Loss of power and propulsion! Not a good thing if you are towing, say, 40 MILES of free-floating gear behind your ship, that just keeps going if you stop. Had to run through pitch-black companionways to get to my computer system and insure that it survived the switch from ship's power to UPS. All was well, except for 2 machines that were not actually connected to the UPS. Surprise! Anyway, we re-instated power and propulsion, forthwith and motored on ahead. Everything out back eventually settled down and we kept on keepin on. In the end, just a bit of adrenaline. Four more days of this shit.
