I Suppose this incident might be entitled ‘How not to find a lightship’. It took place in the 1930s while I was serving in the M.S. Potter, one of the United States Line's long-haul cargo motorships of the period. She was a three-island, fivehatch ship which could lift eight-thousand tons and move it at eleven knots. She was my home for five years and wound up as part of a breakwater at the Normandy beachhead.
