Patent ID: 7216603

Claim:
A structure for use in a body of water, which comprises: (a) a structure having at least a first level; (b) at least a pair of wheels that can be at least temporarily attached to the structure to allow the structure to be transported by ground by rolling the structure over the ground; (c) a buoyancy system carried on the structure to selectively provide the structure with a buoyant state in which the structure floats on the body of water and a non-buoyant state in which the structure does not float on the body of water; and (d) wherein the structure is selectively variable in width to reduce the width of the structure when the structure is being transported by ground compared to the width of the structure when the structure is in the non-buoyant state and is in use in the body of water, wherein the structure is configured to be split into a plurality of separable sections that extend completely through the structure along one dimension of the structure, wherein the separable sections of the structure may be separated from one another for separate ground transport of each section, wherein each section has a transport width that is less than the width of the structure when the sections of the structure are assembled together.
