The USS Clarinda (SP-185), later designated YP-185, was an armed yacht serving as a patrol vessel in the United States Navy from 1917 to 1930. Originally constructed in 1913 by the Matthews Boat Company in Port Clinton, Ohio, Clarinda was a civilian twin-screw motor yacht. Her design reflected the typical features of luxury motor yachts of the period, with twin propellers providing maneuverability and power for her intended civilian use. The U.S. Navy acquired her on July 5, 1917, amid the United States' entry into World War I, and she was commissioned as USS Clarinda (SP-185) on November 21, 1917. Her primary assignment was within the 6th Naval District, with her home base established at Charleston, South Carolina. During her wartime service, she performed patrol and pilot duties, contributing to the maritime security efforts along the southeastern coast of the United States. In 1920, her classification was changed from a section patrol craft (SP-185) to a district patrol craft (YP-185), reflecting her ongoing role in coastal patrol duties. She remained in service well after the conclusion of World War I, continuing her patrol functions through the 1920s. Her operational service lasted until December 26, 1930, when she was decommissioned at the Charleston Navy Yard. Following her decommissioning, Clarinda was sold on June 1, 1931. Her service history exemplifies the utilization of civilian vessels converted for military purposes during wartime, and her long-term patrol duties highlight her importance in maintaining coastal security during her years of active service.
