ABSTRACT OF THE DISCLOSURE SAIL ASSEMBLY A skate sail is rigged with leading edge spars set by manipulation of a cruciform frame. The sail and frame assembly is suitable for mounting on a boat or vehicle as well as for being hand held, and is collapsible for compact stowing. When provided with a cinch line the sail assembly can be used for hang gliding. Rigging is set by joining separable lengths of a mast and advancing a transverse brace along the mast toward the mast head to deploy by toggle-like action head spars to which the sail is lashed thereby spreading and drawing taut a trapezium configuration of sail foil which is anchored to the foot of the mast. Laterally extendable wings may be provided and deployed separately to provide troughs which catch air spilling from the main sail foil and eas handling of the sail and enhance the ability of a user to trim the sail readily.
