The generally accepted meaning for the term "Tractor Tug" is a tug that would supply maneuvering and/or docking traction for vessels lacking that ability. Tractor tugs with Z-drive (or azimuth thruster) propulsion systems, were especially designed for tasks such as ship docking and marine construction. Conventional propeller/rudder configurations are more efficient for port-to-port towing.
This design is twin screw Utility Tug completely outfitted and equipped for maintenance, workboat and other related duties. The Vessel will be classed for Unrestricted Service.
