The Harbor class tugs were designed specifically, for ship assist, and escort duties. She features a hydrofoil shaped skeg, that provides for greatly improved steering, control, and seakeeping. It allows the vessel to run at high speeds in the skeg-first direction. In addition the hydrodynamics of the hull result in increased tons of steering, and braking force. Which are available to assist, or control a vessel at higher speeds.

Powered by two, Caterpillar 3516-B diesel engines. With two, Voith-Schneider cycloidal drives. The tug is rated at 4,800 horsepower.
