    Dictionary of American Naval Fighting Ships:


    A mythical island in the Arthurian legends located somewhere to the west of England and believed to be an earthly paradise.

    Avalon—a motorboat constructed in 1908 at Greenport, Long Island, N.Y., by the Greenport Basin & Construction Co.—was inspected for possible service on section patrol duty and taken into Navy custody on 19 May 1917 by officials of the 3d Naval District. Although her name appeared on, and was struck from, the Navy list, no records have been found that indicate Avalon was ever commissioned by the Navy. The sources, however, suggest that she was in Navy custody until returned to her owner on 22 December 1918. Her name was struck from the Navy list that same day.
