The sailing device has a hull, a framed sail, a boom which is connected at its upper end to the sail by a universal connection located at the center of gravity of the sail, a vertical mast, an auxiliary boom pivotally connected at its lower end to the mast and at its upper end to a bar which is adjustably connected to the mast to vary the angle of the auxiliary boom, the auxiliary boom and the bar being rotatable as a unit about the axis of the mast and the boom being detachably connected to the auxiliary boom in parallel relation thereto. Preferrably, the sail framing is collapsible for handling and storage.

1. Sailing apparatus comprising: a hull; a vertical mast connected to and extending upwardly from said hull; a tubular member concentric with and rotatable about the axis of said mast; a boom; an auxiliary boom connected at its lower end to said tubular member for pivotal movement about a horizontal axis; first connecting means joining said boom and said auxiliary boom in parallel relation; a sail assembly including a frame and a fabric cover; second connecting means joining the upper end of said boom to said sail assembly and permitting pivotal movement of said sail assembly relative to said boom; and means connected to said mast and said auxiliary boom for controllably positioning said auxiliary boom, said boom carried thereby and said said assembly, said lastmentioned means including a control bar attached to said auxiliary boom adjacent the upper end thereof, extending generally horizontally past said mast when in its operative position, and adjustably connected to said mast. 2. The sailing apparatus of claim 1 wherein said second connecting means is located at the center of gravity of said sail assembly. 3. Sailing apparatus comprising: a hull; a vertical mast connected to and extending upwardly from said hull; a tubular member concentric with and rotatable about the axis of said mast; a boom; an auxiliary boom connected at its lower end to said tubular member for pivotal movement about a horizontal axis; first connecting means joining said boom and said auxiliary boom in parallel relation; a sail assembly including a frame and a fabric cover, said sail assembly frame including a first framing member extending along the leading edge of said sail assembly, a pair of second framing members connected, respectively, at the first ends thereof to opposite ends of said first framing member and extending along opposite sides of said sail assembly, a third framing member connected to said first framing member at the midpoint thereof and extending parallel to said pair of second framing members, and fourth framing members connected between the second ends of said second framing members and said third framing member; second connecting means located at the center of gravity of said sail assembly joining the upper end of said boom to said sail assembly and permitting pivotal movement of said sail assembly relative to said boom; and means connected to said mast and said auxiliary boom for controllably positioning said auxiliary boom, said boom carried thereby and said sail assembly. 4. The sailing apparatus of claim 3 wherein said framing members are interconnected by releasable connector means whereby said sail assembly may be collapsed. 5. The sailing apparatus of claim 1 wherein said hull is a surfboard type hull. 6. Sailing apparatus comprising: a hull; a vertical mast connected to and extending upwardly from said hull; a tubular member concentric with and rotatable about the axis of said mast; a boom; an auxiliary boom connected at its lower end to said tubular member for pivotal movement about a horizontal axis; first connecting means joining said boom and said auxiliary boom in parallel relation; a sail frame having a leading edge framing member, a pair of side edge framing members connected, respectively, to opposite ends of said leading edge framing member, a central framing member connected to the midpoint of said leading edge framing member and extending parallel to said side edge framing members, and rear framing members connected between said side edge framing members and said central framing member; a sail fabric carried by said sail frame; second articulated connecting means attaching the upper end of said boom to said central framing member at the center of gravity of said sail frame and sail fabric assembly; first control means for controlling the position of said boom; and second control means for controlling the position of said sail assembly. 7. The sailing apparatus of claim 6 wherein said sail frame is collapsible. 8. The sailing apparatus of claim 7 wherein said mast is removably connected to said hull. 9. The sailing apparatus of claim 6 wherein said first control means includes a control bar attached to said auxiliary boom adjacent the upper end thereof, extending generally horizontally past said mast when in its operative position, and adjustably connected to said mast. 10. The sailing apparatus of claim 6 wherein said second control means includes a fair lead mounted on said hull rearwardly of said mast and a line attached at one end to said sail frame, extending through said fair lead, and securable at its opposite end to said mast. 11. A sail frame adapted for use with a sailing craft of the type having a hull, a mast, and a boom connected at one of its ends to said mast and at the other of its ends to the sail frame comprising: a pair of first framing members extending along the leading edge of the sail; a pair of side framing members, one end of each side framing members being pivotally connected to one end of one of said first framing members, the side framing members extending perpendicular to the first framing members in the operative position of said sail frame; a central tubular framing member pivotally connected to the other end of each of said first framing members, said central framing member being located midway between and parallel to said side framing members in the operative position of said sail frame; a pair of rear framing members, one end of each rear framing member being pivotally connected to the other end of one of said side framing members; and a connector assembly slidably carried on said central framing member and pivotally connected to the other ends of said rear framing members.
