Advanced Bow Thruster Efficiency Aided By Stator Screen From Shipwrights

An unusual new stator screen has been developed to significantly increase the efficiency and power in bow thrusters. Harnessing the power from the water moved by the thruster's twin props is an advancement in bow thruster technology, now exclusive to the Twin Prop system manufactured by Shipwrights, Inc. of Framingham, Mass.

Most screens only keep potentially damaging debris from reaching the props. The screens, typically fabricated by the boatyard handling installation, are not an integral part of the system's design or function.

In the Twin Prop system, the stator screen is cast in nickel/bronze/ aluminum at the factory. The screen not only keeps debris away from the props, but also plays an important part in producing the highly efficient level of thrust for which Twin Prop systems are well known.
