operating conditions. The use of 5 blades not only reduces propeller-induced vibration levels, but also increases the thickness/chord ratio of the blade section. This makes the blade sections much less sensitive to cavitation when operating in non-uniform inflow common to workboats. The given nonlinear skew distribution provides the hydrodynamic equivalent of 36 degrees of linear skew while maintaining the structural strength of an unskewed propeller. This feature, combined

and reduce blade area which contributes to improved propeller efficiency. In addition, the new blade sections incorporate a flat pressure face for ease of manufacture and repair. Sophisticated structural finite element analysis and generous blade edge thicknesses insure structural integrity of the new blade design. The end product is a propeller that delivers optimum cavitation and vibration performance while maintaining the structural and maneuvering characteristics of a standard series workwheel.

Above weights are based on estimates. For weight-critical projects, consult factory. Anti-singing chiseled edges are applied as standard on all five blade propellers and offered as an option on three and four blade designs.
