USS Polly (SP-690)

USS Polly (SP-690) was a United States Navy patrol vessel in commission from 1917 to 1919.

Polly was built as the private motorboat Howmornel by the New York Yacht, Launch and Engineering Company at Morris Heights in the Bronx, New York, in 1909. She later was renamed Kakhin IV and Polly.

On 14 May 1917, the U.S. Navy purchased Polly from William H. Merriman, of New Haven, Connecticut, for use as a section patrol boat during World War I. She was commissioned at Newport, Rhode Island, as USS Polly (SP-690) on 15 May 1917 with Chief Quartermaster H. L. Wakeman, USNRF, in command.

Assigned to the 2nd Naval District in southern New England, Polly carried out patrol duties for the rest of World War I.

Polly was stricken from the Navy List on 11 March 1919 and transferred to the United States Bureau of Fisheries on 9 September 1919.
