Claim 2

A carriage for supporting a sailboat such that the sailboat can be operated on land or on ice, the carriage comprising:

Claim 3

a frame including a pair of generally spaced apart elongated structural members adapted to extend along opposite sides of a sailboat, said elongated structural members being adapted to be positioned under the sailboat with one of said elongated structural members positioned under one side of said sailboat and with the other of said elongated structural members positioned under the other side of said sailboat and to support the sailboat thereon, and with a portion of said sailboat cradled between said elongated structural members and extending downwardly between said elongated structural members, the elongated structural members being parallel to the center line of the sailboat and each including forward ends adapted to support the bow of the sailboat and rearward ends adapted to support the stern, and a forward frame member extending transversely to said parallel elongated structural members and connecting said forward ends of said elongated structural members, said forward frame member including opposite ends, and said forward frame member being adapted to be positioned beneath the bow of the sailboat so as to support the bow, said frame defined by said elongated structural members and said forward frame member being resilient and flexible so as to be adapted to resiliently support the sailboat for movement of a sailboat in water, a first ground engaging member supporting one of said opposite ends of said forward frame member, a second ground engaging member supporting the other of said opposite ends of said forward frame member, and a pivotable ground engaging member for supporting the stern of the sailboat, said pivotable ground engaging member supporting the rearward ends of said elongated structural members.

Claim 4

a frame including a pair of generally spaced apart elongated structural members adapted to extend along opposite sides of a sailboat, said elongated structural members being adapted to be positioned under the sailboat with one of said elongated structural members positioned under one side of said sailboat and with the other of said elongated structural members positioned under the other side of said sailboat and to support the sailboat thereon, and with a portion of said sailboat cradled between said elongated structural members and extending downwardly between said elongated structural members, the elongated structural members being parallel to the center line of the sailboat and each including forward ends adapted to support the bow of the sailboat and rearward ends adapted to support the stern, and a forward frame member extending transversely to said parallel elongated structural members and connecting said forward ends of said elongated structural members, said forward frame member including opposite ends, and said forward frame member being adapted to be positioned beneath the bow of the sailboat so as to support the bow, said frame defined by said elongated structural members and said forward frame member being resilient and flexible so as to be adapted to resiliently support the sailboat for movement of a sailboat in water, a first ground engaging member supporting one of said opposite ends of said forward frame member, a second ground engaging member supporting the other of said opposite ends of said forward frame member, and a pivotable ground engaging member for supporting the stern of the sailboat, said pivotable ground engaging member supporting the rearward ends of said elongated structural members.

Claim 5

A carriage as set forth in claim 1 wherein said elongated structural members are comprised of elongated flexible aluminum tubes.

Claim 6

A carriage as set forth in claim 1 and further including means for releasably joining the forward ends of said elongated structural members to said forward frame member.

Claim 7

A carriage as set forth in claim 3 wherein said means for releasably joining includes means for supporting said forward ends of said elongated structural members for adjustable slidable movement toward and away from each other on said forward frame member.

Claim 8

A carriage as set forth in claim 1 wherein said forward frame members are of sufficient length that said opposite ends extend outwardly beyond the sides of a sailboat supported on the carriage.

Claim 9

A carriage as set forth in claim 1 and further including means for pivotably connecting the pivotable ground engaging member to the rearward ends of said elongated structural members, said means for pivotably connecting including means for supporting said ground engaging member for pivotable movement about a generally vertical axis.

Claim 10

A carriage as set forth in claim 6 wherein said means for pivotably connecting includes a frame member having opposite ends, one of said opposite ends being joined to a rearward end of one of said elongated support members and the other of said opposite ends of said frame member being joined to a rearward end of the other of said elongated support members.

Claim 11

A carriage as set forth in claim 7 wherein said means for pivotably connecting further includes a sleeve fixed to said frame, said sleeve having a generally vertical longitudinal axis, a shaft housed in said sleeve for rotation about said longitudinal axis, said pivotable ground engaging member being connected to a lower end of said shaft housed in said sleeve, and said shaft housed in said sleeve including an upper end, and a tiller connected to said upper end.

Claim 12

A carriage as set forth in claim 1 wherein said ground engaging members comprise runners adapted to support the carriage for movement over ice.

Claim 13

A carriage as set forth in claim 1 wherein said ground engaging members comprise wheels.

Claim 14

A carriage as set forth in claim 1 wherein said ground engaging members comprise skis.
