The 105-foot Harbor Class tractor tugs are U.S.-flag vessels designed for ship assist and escort. These tugs feature Voith Schneider twin cycloidal propulsion and a hydrofoil-shaped skeg that provides for greatly improved steering, control and seakeeping ability when the vessel is running at high speeds in the skeg-first direction. In addition, the unique 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.
Crowley innovations incorporated into the design of these tugs include a pilothouse control console arranged for maximum visibility and ease of use.
All Crowley tugs are fully instrumented, with pilothouse-controlled engine rooms, and are equipped with the latest in navigational and communications technology.
