Mimac (YTB-507)

Apparently a variant spelling of Mi'kmaq [Micmac], people indigenous to Canada's Maritime Provinces, the Gaspee Peninsula, or areas in the northeastern part of the state of Maine.
(YTB‑507: displacement 218; length 100'; beam 28'; draft 9'7"; speed 12 knots; class Cholocco)
Mimac (YTB‑507) was laid down on 4 January 1945 at Portland, Oregon, by Commercial Iron Works; launched on 17 May 1945; and placed in service on 17 July 1945.
Assigned to the Thirteenth Naval District, headquartered at Seattle, Mimac has served into 1960 assisting larger vessels in berthing and docking, and providing towing services and waterfront firefighting protection. She was reclassified YTM‑770 on 1 April 1966. Ultimately placed out of service and stricken from the Naval Vessel Register in 1985, Mimac was disposed-of, by Navy Sale, on 27 March 1987.
Acquired by the Island Barge and Tow Co., of Seattle, the ship was renamed Paula S., and served as such until bought by the Northwest Marine Equipment Leasing Co. of Anacortes, Wash., in 2012. Redocumented as Ambitious, she was earmarked for conversion to a tender, in the commercial fishing trade. As of the year 2017, she was in a lay-up status, in the Lovioc's Marine yard at Anacortes.
