... on the heel resistance are substantial for the range of heel angles for both speeds. In practical sailing conditions, the heel angle is accompanied by the leeway angle as aerodynamic heeling force must be balanced by a hydrodynamic side force which can only generated by a leeway angle. Hence heel resistance...
