USS Calabash (SP-108)

USS Calabash (SP-108) was an armed motorboat that served in the United States Navy as a patrol vessel in 1917. Calabash was built as a civilian motorboat in 1912 by Mathis Shipbuilding Company at Camden, New Jersey. She was the property of a resident of Coconut Grove, Florida, when the U.S. Navy acquired her on 25 July 1917 for use as a patrol boat during World War I. She was commissioned the same day as USS Calabash (SP-108).

Apparently found unsuitable for naval service, Calabash served for less than a month before being decommissioned and returned to her owner in August 1917.
