The Effect of Hull Form and Above Water Configuration on the Re-Righting of Sailing Yachts in Waves

Three yacht hulls have been used to experimentally investigate the effects of hull form and above water configuration on re-righting ability. The three hull forms were chosen to represent a broad spectrum of the current 40 foot racing yacht fleet. Correlation of re-righting performance with basic hydrostatic parameters has been shown to a limited degree for these three hulls. However three simple cases of varying above water configuration have resulted in this correlation being non-existent.
