This invention relates to the use of a removably attachable sailing rig with an integrated water foil for the conversion of a conventional boat, row boat, kayak, canoe, and power boat into a sailboat or an existing sailboat rig into a canting sail rig. The sail rig system utilizes the strong attachment points inherently available on most conventional boats and soft inflatable boats for attachment. The sail rig is comprised of a mast with an integrated water foil and is supported by a strut on each side forming a tripod with the mast, a sail is attached to the mast which is unconventionally tacked or jibed around the front of the mast in order to clear the struts. The base of each strut has a strut attachment assembly for direct attachment to an oar lock or shear of a boat. The base of the mast has a mast attachment assembly for direct attachment to the bow or bow towing ring. The mast and water foil can be tilted or canted to either side of the boat by lengthening or shortening each strut. The sail rig system also has a separate rudder assembly for steering.

I claim: 1. An attachable sail rig provided for a boat having a longitudinal axis and a vertical axis, a bow, a bow towing ring, a transom, and a port and starboard side, a shear, and a fore and aft end, with said boat in the water having a water surface, comprising:a mast with a base located at one end having a lower section and a front side facing said bow, and an axis parallel to said mast and said vertical axis of said boat when said mast is vertical;a mast attachment assembly on said base of said mast providing pivotal attachment to said bow;a strut on said port side and said starboard side of said boat each having a base and an upper end and a lower end;a strut attachment assembly on said base of said strut providing pivotal attachment of said strut, enabling each said strut to pivot relative to said port and starboard side of said boat when attached to said boat thereof;a mast strut attachment assembly on said mast providing pivotal attachment of said upper end of each said strut to said mast above said base of said mast, forming a tripod with said lower section of said mast and enabling each said strut to pivot relative to said mast;a sail having a luff and said luff attached to said mast with said sail on said front side of said mast outboard of each said strut, enabling said sail with said luff to be tacked or jibed completely around said front side of said mast and each said strut from said port side to said starboard side of said boat and back;a water foil assembly mounted pivotal substantially along the longitudinal axis of said boat on said base of said mast extending in front of said bow below said water surface, enabling an operative position to resist lateral wind forces and to retract from the operative position in an inoperative position above said water surface, and removable from said base of said mast;a rudder assembly pivotally mounted on said transom of said boat extending below said water surface, enabling an operative position to resist lateral wind forces and provide steering of said boat and to retract from the operative position in an inoperative position above said water surface.
