Abstract

Abstract A non-heeling sailing vessel having: a payload bearing first displacement hull with a pair of longitudinally spaced control surfaces rigidly mounted thereto in fixed alignment and extending downwardly therefrom into the water, a rigid support structure rigidly fixed to said hull and extending laterally, at least one upstanding sail rigidly mounted to the support structure, the sail being spaced laterally of and inclined toward the control surfaces for generation of a resultant force directed away from the control surfaces and upwardly in response to the wind, and, a second displacement hull mounted to the support structure intermediate the first displacement hull and the sail.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 106 words
A non-heeling sailing vessel comprising: a payload bearing first displacement hull having a pair of longitudinally spaced control surfaces rigidly mounted thereto in fixed alignment and extending downwardly therefrom into the water; a rigid support structure rigidly fixed to said hull and extending laterally thereof; and at least one upstanding sail rigidly mounted to said support structure, said sail being spaced laterally of and inclined toward said control surfaces for generation of a resultant force directed away from said control surfaces and upwardly in response to the wind and, a second displacement hull mounted to said support structure intermediate said first displacement hull and said sail.
Claim 2
Dependent Claim 106 words
A non-heeling sailing vessel comprising: a payload bearing first displacement hull having a pair of longitudinally spaced control surfaces rigidly mounted thereto in fixed alignment and extending downwardly therefrom into the water; a rigid support structure rigidly fixed to said hull and extending laterally thereof; and at least one upstanding sail rigidly mounted to said support structure, said sail being spaced laterally of and inclined toward said control surfaces for generation of a resultant force directed away from said control surfaces and upwardly in response to the wind and, a second displacement hull mounted to said support structure intermediate said first displacement hull and said sail.
Claim 3
Dependent Claim 23 words
A non-heeling sailing vessel as defined by claim 1 comprising means for selectively varying the wetted area of each of said control surfaces.
Claim 4
Dependent Claim 26 words
A non-heeling sailing vessel as defined by claim 1 comprising means for adjusting the angle of rotation of said sail with respect to said support structure.
Claim 5
Dependent Claim 26 words
A non-heeling sailing vessel as defined by claim 1 comprising means for adjusting the angle of inclination of said sail with respect to said support structure.
Claim 6
Dependent Claim 39 words
A non-heeling sailing vessel as defined by claim 1 comprising means for selectively varying the wetted area of each of said control surfaces and the angles of rotation and inclination of said sail with respect to said support structure.
Claim 7
Dependent Claim 79 words
A non-heeling sailing vessel as defined by claim 1 comprising: a plurality of longitudinally spaced sails rigidly mounted to said support structure, said sails being spaced laterally of and inclined toward said control surfaces for generation of a resultant force directed away from said control surfaces and upwardly in response to the wind; means for rotating said sails with respect to said support structure; and means for adjusting the inclination of said sails with respect to said support structure.
Claim 8
Dependent Claim 42 words
A non-heeling sailing vessel as defined by claim 1 wherein said sail is a rigid airfoil symmetrical in planiform, and said vessel is symmetrical with respect to a vertical plane containing the perpendicular bisector of the longitudinal axis of said first hull.
