Abstract
An arrangement is disclosed which secures the sail to the mast of a sailing craft to achieve an aerodynamic profile about the mast while allowing curvature in the mast for optimum sail profile. The arrangement includes an outer profile sleeve of flexible material extending from a line of securement to the rear of the luff of the sail forwardly around the mast. The profile sleeve receives one or more semi-rigid, flexible profile members comprised of lightweight plastic sections configured to be tightly fit therein, stretching the profile sleeve into a high efficiency wing shape surrounding the mast. The wing shape includes a leading parabolic surface and curved sides smoothly transitioning into the main sail area to create a lift airfoil with the sail angled either to port or starboard.
