Premise: USS "Daiquiri" (SP-1285) was a motorboat – one of a series of identical boats – planned and built by the U.S. Navy in the event they would be needed during World War I. "Daiquiri" was armed as a patrol craft and assigned to New England waterways under the cognizance of the 1st Naval District based at Kittery, Maine. She was sold when the war ended.
Hypothesis: The motorboat was sold.
