Sailing hydrofoil with bow-mounted trim foil - is designed so that lift of foils may be set to work in opposition to counteract heeling

摘要

The sailing vessel rides on stern mounted adjustable foils and has a bow mounted trim foil movable on a longitudinal track. The respective stern foils may generate positive and negative lift simultaneously to counteract heeling, thus exploiting the craft's speed potential. By setting the longitudinal position of the trim foil, equilibrium about a vertical axis is achieved without use of the rudders. The lifting foils are controlled by a common lever which further may have a telescopic action to control the trim foil. The outriggers are pivoted to raise the foils.
