Not too nautical for the landlubber, and absorbing for the blue-water sailors, is this log of an east-west Atlantic run made by a 25-foot sloop in the spring of 1950. The author, an Englishman, was captain and navigator, and with his ""crew"" of one, made the trip from Land's End to New York harbor in 47 days of alternating watches, rest, meal preparation in the tiny galley. The ship itself was the smallest ever to make the Europe to America crossing. Days of sunshine were interspersed with days of high wind, when the sloop shuddered under mast-high rolling waves. There were adventures and nearmisses -- a barnacle encrusted log on a lonely ocean; no landfalls though several ships passed them, constant minor repairs. Diagrams will add to the interest for the small boat fans, but the language won't prove a barrier for the average reader.
