Split-Flaps – a Way to Improve the Heel Stability of T-Foil Supported Craft [PDF]
Journal of Sailing Technology, 2021 Abstract Horizontal T-foils allow for maximum lift generation within a given span. However, the lift force on a T-foil acts on the symmetry plane of the hull, thereby producing no righting moment. It results in a lack of transverse stability during foil-borne sailing.
