Abstract
Abstract The invention contemplates shoring structure for winter or other land-based storage of small boats, such as keeled sailboat hulls, wherein the basic structure is adaptable to the inherently stable and locked retention of each of a relatively wide variety of different hull shapes, and wherein such structure may be collapsed and stored within relatively compact volumetric confines.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
163 words
An adjustable shoring device for stabilized support of a keeled hull, said device comprising an elongate longitudinal frame member, two keel-supporting blocks and means for adjustably clamping said blocks to said frame member at longitudinally spaced locations along said frame member, elongate transverse frame-member means and means for clamping the same to said longitudinal member with a first frame-member portion projecting to one transverse side of said longitudinal frame member and with a second frame-member portion projecting to the other transverse side of said longitudinal frame member, first and second upstanding side-stabilizing structures connected to the respective projecting ends of said first and second frame-member portions, third and fourth upstanding bow and stern stabilizing structures connected to the respective longitudinal ends of said longitudinal frame member, hull-engaging means adjustably carried by upper ends of said stabilizing structures, and means for releasably clamping said hull-engaging means in adjusted position of hull-engagement when the keel of a particular hull is fore-aft supported upon said blocks.
