Wiwoka (S. P. 250), a motorboat built in 1912 at South Boston, Mass., by Murray & Tregurtha, was acquired from Mr. Joseph V. Gallagher of New York on 25 July 1917 and was commissioned on 11 September 1917. Wiwoka patrolled the coastline around New York as a unit of the Section Patrol for the duration of World War I. Shortly after hostilities ceased in November 1918, she was decommissioned, probably in December 1918 since her battery was removed on the 18th, and the motorboat was returned to her owner on 17 January 1919. Her name was struck from the Navy list that same day.
