Abstract
Abstract A boat has a body, a mast arranged on the body so that under the action of a wind force component acting in a first lateral direction transverse to a longitudinal axis the mast turns relative to at least a portion of the body in a first lateral direction, and an element which resists the turning of the mast in the first lateral direction and urges the mast to turn in a second lateral direction which is opposite to the first lateral direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
A boat, comprising a body having a longitudinal axis; a mast arranged on said body so that under the action of a wind component acting in a lateral direction transverse to said longitudinal axis, said mast turns relative to said body clockwise or counterclockwise; and means for connecting said mast with said body so that when said mast is turned clockwise said mast forcedly turns said body counterclockwise and vice versa, said connecting means including at least two rope members each having a distal end which is connected with said body at a location laterally spaced from said mast and proximal end which cooperates with said mast so that when said mast is turned clockwise it pulls said rope member clockwise and thereby pushes said body counterclockwise and vice versa.
Claim 2
Dependent Claim
130 words
A boat, comprising a body having a longitudinal axis; a mast arranged on said body so that under the action of a wind component acting in a lateral direction transverse to said longitudinal axis, said mast turns relative to said body clockwise or counterclockwise; and means for connecting said mast with said body so that when said mast is turned clockwise said mast forcedly turns said body counterclockwise and vice versa, said connecting means including at least two rope members each having a distal end which is connected with said body at a location laterally spaced from said mast and proximal end which cooperates with said mast so that when said mast is turned clockwise it pulls said rope member clockwise and thereby pushes said body counterclockwise and vice versa.
Claim 3
Dependent Claim
50 words
A boat as defined in claim 1, wherein said mast has a lower end, said boat having an inner surface, said rope members being fixedly connected at their distal ends ot said inner surface of said boat and cooperating by said proximal ends with said lower end of said mast.
Claim 4
Dependent Claim
144 words
A boat, comprising a body having a longitudinal axis; a mast arranged on said body so that under the action of a wind component acting in a lateral direction transverse to said longitudinal axis, said mast turns relative tos aid body clockwise or counterclockwise; and means for connecting said mast with said body so that when said mast is turned clockwise said mast forcedly turns said body counterclockwise and vice versa, said connecting emans including at least two gear members which are in engagement with one another, one of said gear members being fixedly connected with said mast and the other of said gear members fixedly connected with said body so that when said mast is turned clockwise said first gear member is turned clockwise and thereby turns said other gear member counterclockwise so as to thereby turn said body counterclockwise and vice versa.
Claim 5
Dependent Claim
144 words
A boat, comprising a body having a longitudinal axis; a mast arranged on said body so that under the action of a wind component acting in a lateral direction transverse to said longitudinal axis, said mast turns relative tos aid body clockwise or counterclockwise; and means for connecting said mast with said body so that when said mast is turned clockwise said mast forcedly turns said body counterclockwise and vice versa, said connecting emans including at least two gear members which are in engagement with one another, one of said gear members being fixedly connected with said mast and the other of said gear members fixedly connected with said body so that when said mast is turned clockwise said first gear member is turned clockwise and thereby turns said other gear member counterclockwise so as to thereby turn said body counterclockwise and vice versa.
Claim 6
Dependent Claim
49 words
A boat as defined in claim 3, wherein said body is provided with two spaced members fixedly connected with said body, said one gear member being pivotably mounted on one of said spaced members, while said other gear member being fixedly mounted on the other of said spaced members.
