In the event of close quarters maneuvering, the operator can stand at any location in the wheelhouse and maintain full control over the vessel.
The tug also features a hybrid cooling system. With both raw water going through a heat exchanger, as well as a traditional freshwater cooling with channels.

Her electrical service is provided by two, 159kW, John Deere 6081AMK330 generator sets. Any of the three generators can handle the electrical demand of the vessel. However one generator handles the demands of the JAK coupler system. Her generators are flexible mounted for the purpose of noise reduction, as well. The tug's capacities are 103,000 gallons of fuel oil, 2,400 gallons of lube oil, 13,000 gallons of wash water, 4,200 gallons of potable water and 2,000 gallons of sewage.
