Ever since Westward Round in the Schooner Yankee back in 1936 set a pattern for the unique travel records of the Johnsons, man and wife, their journeys and the records have been of wide appeal to the sailing fraternity.

A happy-go-lucky Lenor extends to this loosely organized record. Its market has been established.
