USS Alacrity (SP-206)

USS Alacrity (SP-206) was an Alacrity -class patrol boat acquired by the U.S. Navy for the task of patrolling American coastal waters during the First World War.

The first vessel to be named Alacrity by the Navy, SP-206 -- a motorboat constructed in 1910 at Wilmington, Delaware, by Pusey & Jones -- was acquired by the Navy on 28 April 1917 under a free lease from Mr. John H. Blodgett and was placed in commission on 30 May 1917 at Boston, Massachusetts, Ens. Courtland W. Babcock, USNRF, in command.

World War I service
Assigned to the 1st Naval District section patrol, Alacrity spent World War I conducting patrols from the Boston and Provincetown, Massachusetts, section bases.

Post-war activity and decommissioning
Following the armistice in November 1918, the motorboat continued naval service until she was finally returned to her owner on 28 April 1919, the second anniversary of her acquisition. Her name was struck from the Navy list that same day.
