USE OF ANTIPITCH HYDROFOIL TO REDUCE ADDED RESISTANCE OF A YACHT IN WAVES

The use of a horizontal antipitch hydrofoil to reduce the vertical motions and added resistance of a sailing yacht is investigated. The difficulties, limitations and assumptions inherent in studying yachts in waves are discussed. A mathematical model is presented in an attempt to predict the effect of an antipitch foil on the motions and added resistance of the 12-meter CANADA II. Scale model experiments were conducted and the results are presented and compared with the theoretical results. Experimental results show that the antipitch foil is very effective in reducing the motions and added resistantce of the model.
