Abstract
Abstract A pair of outrigger hulls are located on the ends of a wing, to which is movably attached a central hull which can be moved back and forth with respect to the outrigger hulls. A pivotable mast positioned on the central hull allows the central hull to be positioned near the leeward outrigger hull while leaning the mast towards the windward outrigger hull, thereby providing a lift to the craft and a reduction in displacement. Rotary wheels at each end of the wing allow crewmen stationed there to control the position of the central hull along the length of the wing and to control the slack and tautness of a pair of sail lines. A differential apparatus enables crewman to control the rudder from anywhere along the length of the wing independently of the central hull location along the length of the wing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
116 words
A sailing craft, comprising: a wing having first and second ends; first and second outrigger hulls mounted on said first and second ends of said wing, respectively; a central hull located between said first and second outrigger hulls, said central hull being movably connected to said wing, whereby said central hull can be moved closer to either one of said first and second outrigger hulls; and a pivotable mast mounted on said central hull for leaning said mast towards either one of said outrigger hulls, thereby enabling the central hull to be moved towards one of said first and second outrigger hulls and the mast leaned towards the other of said first and second outrigger hulls.
Claim 2
Dependent Claim
116 words
A sailing craft, comprising: a wing having first and second ends; first and second outrigger hulls mounted on said first and second ends of said wing, respectively; a central hull located between said first and second outrigger hulls, said central hull being movably connected to said wing, whereby said central hull can be moved closer to either one of said first and second outrigger hulls; and a pivotable mast mounted on said central hull for leaning said mast towards either one of said outrigger hulls, thereby enabling the central hull to be moved towards one of said first and second outrigger hulls and the mast leaned towards the other of said first and second outrigger hulls.
Claim 3
Dependent Claim
42 words
The sailing craft according to claim 1, being characterized further by a control wheel located at one of the said first and second ends of said wing for moving said central hull back and forth between said first and second outrigger hulls.
Claim 4
Dependent Claim
42 words
The sailing craft according to claim 1, being characterized further by first and second control wheels located at said first and second ends of said wing, respectively, for moving said central hull back and forth between said first and second outrigger hulls.
Claim 5
Dependent Claim
100 words
A sailing craft, comprising: a wing having first and second ends; first and second outrigger hulls mounted on said first and second ends of said wing, respectively; and a central hull located between said first and second outrigger hulls, said central hull being movably connected to said wing, whereby said central hull can be moved closer to either one of said first and second outrigger hulls, said craft including first and second control wheels located at said first and second ends of said wing, respectively, for moving said central hull back and forth between said first and second outrigger hulls.
Claim 6
Dependent Claim
100 words
A sailing craft, comprising: a wing having first and second ends; first and second outrigger hulls mounted on said first and second ends of said wing, respectively; and a central hull located between said first and second outrigger hulls, said central hull being movably connected to said wing, whereby said central hull can be moved closer to either one of said first and second outrigger hulls, said craft including first and second control wheels located at said first and second ends of said wing, respectively, for moving said central hull back and forth between said first and second outrigger hulls.
Claim 7
Dependent Claim
53 words
The sailing craft according to claim 4, including in addition thereto, a rudder located on the underside of said central hull and means running along substantially the entire length of said wing for controlling said rudder independently of the position of said central hull with respect to the first and second outrigger hulls.
Claim 8
Dependent Claim
156 words
A sailing craft, comprising: a wing having first and second ends; first and second outrigger hulls mounted on said first and second ends of said wing, respectively; a central hull located between said first and second outrigger hulls, said central hull being movably connected to said wing, whereby said central hull can be moved closer to either one of said first and second outrigger hulls; a pivotable mast mounted on said central hull for leaning said mast towards either one of said outrigger hulls, thereby enabling the central hull to be moved towards one of said first and second outrigger hulls and the mast leaned towards the other of said first and second outrigger hulls; a rudder located on the underneath side of said central hull; and means running along the length of said wing for controlling said rudder independently of the position of said central hull with respect to the first and second outrigger hulls.
Claim 9
Dependent Claim
156 words
A sailing craft, comprising: a wing having first and second ends; first and second outrigger hulls mounted on said first and second ends of said wing, respectively; a central hull located between said first and second outrigger hulls, said central hull being movably connected to said wing, whereby said central hull can be moved closer to either one of said first and second outrigger hulls; a pivotable mast mounted on said central hull for leaning said mast towards either one of said outrigger hulls, thereby enabling the central hull to be moved towards one of said first and second outrigger hulls and the mast leaned towards the other of said first and second outrigger hulls; a rudder located on the underneath side of said central hull; and means running along the length of said wing for controlling said rudder independently of the position of said central hull with respect to the first and second outrigger hulls.
Claim 10
Dependent Claim
42 words
The sailing craft according to claim 6, including in addition thereto, a control wheel located at one of the said first and second ends of said wing for moving said central hull back and forth between said first and second outrigger hulls.
Claim 11
Dependent Claim
41 words
The sailing craft according to claim 6, being characterized further by first and second wheels located at said first and second ends of said wing, respectively, for moving said central hull back and forth between said first and second outrigger hulls.
Claim 12
Independent Claim
