Resistance Measurements of Typical Planing Boat Appendages

Abstract

Full size models of typical planing boat appendages were assembled in four basic configurations. Towing basin experiments were performed to determine their drag and lift characteristics. The results are compared with predicted values derived from published empirical formulas. Experimental drag is found to be higher than the predictions, and the lift displays a speed dependence that is not considered by the existing prediction method.
