Wind Powered Watercraft

Abstract

A sail driven watercraft includes a hull, a deck coupled to the hull, and a mast coupled to the hull to extend upwardly and carry one or more sails. The hull extends downwardly from the deck into water in which the sail driven watercraft floats.

1 . A boat comprising
 a structural element,   a first hull coupled to the structural element to move relative to the structural element between an extended position in which the first hull is a first distance from the structural element and a retracted position in which the first hull is a relatively smaller second distance from the structural element, and   a second hull coupled to the structural element to locate the structural element between the first and second hulls, the second hull is movable relative to the structural element and the first hull between an extended position in which the second hull is the first distance from the structural element and the retracted position in which the second hull is the relatively smaller second distance from the structural element.   
     
     
         2 . The boat of  claim 1 , further comprising a mast coupled to the structural element to move about a pivot axis between a raised position in which the mast is arrange to extend upwardly away from the structural element to cause the boat to have a first height and a lowered position in which the mast is arranged to extend along generally parallel to the structural element to cause the boat to have a relatively smaller second height. 
     
     
         3 . The boat of  claim 1 , further comprising a deck including a first deck section coupled to the structural element to pivot about a first hinge axis between a flat position in which the first deck section lies generally flat and extends between the structural element and the first hull when the first hull is in the extended position and an upright position in which the first deck section lies generally upright relative to the first hull when the first hull in is the retracted position. 
     
     
         4 . The boat of  claim 3 , wherein the deck further includes a second deck section coupled to the structural element to pivot about a second hinge axis between a flat position in which the second deck section lies generally flat and extend between the structural element and the second hull when the second hull is in the extended position and an upright position in which the second deck section lies generally upright relative to the second hull when the second hull in is the retracted position. 
     
     
         5 . The boat of  claim 3 , further comprising a first hinge arm arranged to extend between and interconnect the first deck section and the structural element to cause the first deck section to pivot about the first hinge axis. 
     
     
         6 . The boat of  claim 3 , further comprising a wheel unit coupled to the structural element to pivot about a pivot axis between a raised position in which the wheel unit is arranged to extend generally parallel to the first deck section when the first hull is in the extended position and a lowered position in which the wheel unit is arranged to extend downwardly away from the structural unit to cause a wheel included in the wheel unit to contact ground and support the boat for rolling movement over ground underlying the boat. 
     
     
         7 . The boat of  claim 6 , further comprising a trailer arm coupled to the structural element to move relative to structural element between a retracted position in which the boat has a first length and an extended position in which the boat has a relatively greater second length. 
     
     
         8 . The boat of  claim 7 , wherein the trailer arm includes an arm slide coupled to the structural element to slide back and forth along a longitudinal axis of the of the boat, a hitch beam including a proximal end coupled to the arm slide to cause the hitch beam to pivot about a trailer axis between a storage position in which the hitch beam extends from the trailer axis toward a rear end of the boat and a use position in which the hitch beam extends away from the trailer axis and the rear end of the boat, and a hitch receptacle coupled to a distal end of the hitch beam opposite the proximal end of the hitch beam and adapted to mate with a hitch included in a tow vehicle.
