The Towmaster™ Nozzle/Rudder System can cut your turning circle by 70%

If your vessel has a ducted propeller system, Michigan Wheel's Towmaster

Nozzle/Rudder System can give you a dramatic improvement in maneuver- ability and turning effi- ciency. In fact, if your vessel presently has a fixed nozzle system, tests prove the

Towmaster

Nozzle/

Rudder System could reduce your turning circle by 70%. If yours is an open propeller system, you can expect an improvement of up to 60%.

The Towmaster can give you this kind of performance because of its unique triple-rudder design. Each rudder, by itself, produces a higher lift-to-drag ratio than conventional centerline rudders.

Together, they create a cascade effect that can allow 60 ° helm angles before rudder stall occurs.

And because the Towmaster also re- duces rudder torque and makes more efficient use of propeller thrust, vessel operation is easier and less fatiguing.
