I single hand our 44 most of the time...often in fog and/or at night crossing Lake Michigan...typically an eleven hour trip to final destination in Wisconsin. One crappy, bumpy night (no fog) I did my hourly engine room check about mid-Lake and discovered a serious leak in one of the raw water pumps. After shutting that engine down, I checked the radar and scanned the horizon for lights. With none noted I set the autopilot on the proper course while running at slightly reduced speed on the remaining engine. The Will-Hamm autopilot kicked the rudder over to maintain course and I went below to change out the pump. Every ten minutes I'd pop up, check the radar, and do the visual scan. Beat the heck out of wallowing around in the trough while doing the repair, or poking along on one engine and arriving after the destination marina closed. The beauty of an autopilot (and two engines). I won't leave port on an extended trip without it.
