Built in 1965, by the Pacific Coast Engineering Company (PACECO) of Alameda, California (hull #208) as the Intrepid for Crowley Marine Services Incorporated of San Francisco, California.

She was the second 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.

The tug rolled over and sank in a gale February 19, 1970 in the Gulf of Alaska, 60 miles south of Yakutat. Three of the eight crewmembers on board were lost. Five other crew members survived more than 60 hours in a life raft until rescued by the U S Coast Guard buoy tender Clover. The 400 foot long barge Cordova that the Intrepid was towing washed ashore near Yakutat at Dangerous River and was later salvaged.

She was powered by a single, EMD 16-645 E5 diesel engine. With a Falk reduction gear, at a ratio of 4.536.1. Turning a single, fixed pitch, five bladed, 122(in) by 98(in) propeller. For a rated 2,200 horsepower.

Her electrical service was provided by two Caterpillar 3306 110 kW/AC generator sets. The tug's capacities are 60,000 gallons of fuel oil, 40,000 gallons of ballast, 18,000 of fresh water, and 2,200 gallons of lube oil.

The towing gear consisted of an Almon Johnson 222, towing winch. Outfitted with 2,000(ft) of 2(in) towing wire.
