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.
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.

In 2012, the tug was acquired by the Island Trader Shipping Company of Union County, New Jersey. Where she was renamed as the Sea Racer. Where she operates under a Guyana flag.
