Abstract
The sailing vessel of the present invention includes a hull of omnidirectional construction, and a generally triangular sail which is supported along two side edges, with the third side edge unsupported and extending generally horizontally. The angular position of the sail with respect to the hull is fixed, and the heading of the boat is varied in order to orient the sail at the desired angle with respect to the wind. A pivotally mounted centerboard controls the direction or heading of the boat and control lines are provided for altering the shape of the sail to further control the direction and speed of sailing.
Claims13
A sailing vessel comprising the combination of:
- (a) omnidirectional hull means,
- (b) a sail,
- (c) sail support means carried by said hull means and extending upwardly therefrom and cooperating with said sail for supporting two side edges thereof along intersecting angularly upwardly extending axes while leaving a third side edge of said sail unsupported and extending generally horizontally,
- (d) sail control means connected to said third side edge of said sail medially of the adjacent corners of the sail and cooperating with said hull for pulling the sail laterally so as to alter the shape of the sail,
- (e) a centerboard positioned beneath said hull and mounted for pivotal movement about a substantially vertical axis, and
- (f) a centerboard control cooperating with said centerboard and positioned for operation by the sailor of said vessel for adjusting the pivotal position of said centerboard relative to said hull for assisting in controlling the direction of movement of said vessel.

A sailing vessel comprising the combination of:
- (a) a buoyant hull of a substantially circular disclike configuration,
- (b) a generally triangular sail,
- (c) sail support means carried by said hull and extending upwardly therefrom and cooperating with said generally triangular sail for supporting two side edges thereof along intersecting angularly upwardly extending axes while leaving the third side edge of said sail unsupported and extending generally horizontally,
- (d) sail control means connected to said third side edge of said sail medially of the adjacent corners of the sail and cooperating with said hull for pulling the sail laterally so as to alter the shape of the sail,
- (e) a centerboard positioned beneath said hull and mounted for pivotal movement about a substantially vertical axis located generally in the center of the circular disc-shaped hull, and
- (f) a centerboard control cooperating with said centerboard and positioned for operation by the sailor of said vessel for adjusting the pivotal position of said centerboard relative to said hull for assisting in controlling the direction of movement of said vessel.
3 more elements
A sailing vessel comprising the combination of:
- (a) three buoyant hull members of circular disclike configuration,
- (b) frame means connected to the upper sides of said hull members and extending upwardly therefrom for rigidly interconnecting said hull members,
- (c) means associated with said frame means and defining a deck for receiving one or more passengers thereon,
- (d) a generally triangular sail,
- (e) sail support means carried by said frame means and extending upwardly therefrom and cooperating with said generally triangular sail for supporting two side edges thereof along intersecting angularly upwardly extending axes while leaving the third side of the sail unsupported and extending generally horizontally,
- (f) sail control means connected to said third side edge of said sail medially of the adjacent corners of the sail and cooperating with said sail for pulling the sail laterally so as to alter the shape of the sail,
- (g) a centerboard extending vertically and beyond said hull members and mounted for pivotal movement about a substantially vertical axis, and
- (h) a centerboard control cooperating with said centerboard and positioned for operation by the sailor of said vessel for adjusting the pivotal position of said centerboard relative to hull members for assisting in controlling the direction of movement of said vessel.
