Built in 1966, by the Pacific Coast Engineering Company (PACECO) of Alameda, California (hull #212) as the Sea Racer for Crowley Marine Services Incorporated of San Francisco, California.
She was the sixth Daring class tug constructed by the Pacific Coast Engineering Company for Crowley Marine Services Incorporated.
Designed by Naval Architect Phil Spaulding, the Daring class was the first class of tugs constructed for Crowley Marine Services. The design featured a simplified engine room. As well as gauges, alarms, and controls for the engine room in the wheelhouse. This allowed the company to reduce the manning of the tug from twelve men, to eight, in an effort to give Crowley Marine an advantage over their competition.
