I TOWMASTER™

Michigan

Wheel

Corporation

The ultimate in maneuverability.

Virtually any vessel operating with a ducted propeller system can realize impressive gains in overall turning efficiency and ma- neuvering with a Michigan Wheel

Towmaster Rudder System.

The heart of every Towmaster

System involves the utilization of three high aspect ratio rudders.

Individually, each Towmaster rud- der produces a higher lift to drag ratio than conventional center- line rudders. Collectively,

Towmaster's triple rudders create flow variations on themselves—a cascade effect—which permits 50 helm angles before rudder stall occurs. The result is im- pressive. Research documents

Based upon single ^crew results that when a Towmaster System is compared with fixed nozzle and cpen propeller systems, turning diameters are routinely reduced by 90% and 65%. respectively.

When increased maneuverability and station keeping capability can lower operational costs and increase vessel profitability ana safety, the logic of installing a

Michigan Wheel Towmaster Rud- der Svstem becomes clear.

The original Towmaster

System was introduced in 1967 by the respected marine design firm

Burness, Corlett & Part- ners, Ltd. (BCP). Now that

Michigan Wheel Corp. (an industry innovator for over 75 years)possesses the exclusive domestic sales and design rights to the Towmaster

System, North American ship operators can take advantage of the combined technological exper- tise of Michigan Wheel and 8CP.
