The King County Sheriff’s Office marine division has selected Moose Boats to build a new, 46' custom diesel electric hybrid patrol boat. The model M1 will be powered by two Volvo Penta D11 diesel engines each producing 625-hp. The mains will be integrated with in-line twin Danfoss electric motors — A first of its kind for public safety..... The new vessel will be a close collaboration between HamiltonJet, who has designed the electric propulsion system, Volvo Penta and Moose Boats. Current battery technologies manufactured by Corvus Energy will enable the vessel to run solely under electric propulsion for up to two hours at 5 knots. Integrated diesel drive engines will act to replenish batteries at a rapid rate with electric motor boost to enhance upper end speed performance.

Hamilton AVX Express will allow for tight-quarter maneuverability through joystick controls with Jet Anchoring capabilities. The system also includes a hand- held remote that will enable the vessel to be piloted from different places within the confines of the cabin.
