The tug is a SDM (Ship Docking Module) Seabulk Towing holds the patent license on the SDM design. The engines are coupled to the z-drives, mounted along the centerline of the tug which incorporate the speed reduction gearing, and steering, allowing the propeller, and nozzle to rotate 360 degrees.
SDM tugs where constructed with a semi flat bottom to the hull. With two, diametrically opposed azimuthing z drives. Which allow for 100 percent of the tug's 120,000(lbs) of bollard pull to be applied in any direction while stationary against a ship’s hull.
The tug can theoretically propel itself sideways at six knots, forward, and astern at up to 12.5(kts). The boats are stabilized in the water with 12(ft) skegs forward, and aft. While in a ship assist mode, the SDM’s centrifugal, fendering system allows the boat to utilize every point of its hull to control and maneuver a ship.
