In a watercraft storage system a “wishbone” or U-shaped cradle liftable and rotatable by an overhead crane comprises adjustable air filled hull supports to either side of a boat hull and a keel support toward the stern of the watercraft. The cradle central opening clears a cantilever storage rack support beam assembly allowing the watercraft to be lowered onto or raised from the cantilever storage rack support beam assembly by an overhead traveling crane. To substantially reduce any longitudinal swaying of the cradle and watercraft during raising and lowering, a system or diagonal anti-sway bracing cables that automatically retract and extend is employed. In the preferred embodiment, the cradle is lowered into a water-filled channel within the storage structure to re-float the watercraft. A watercraft to be stored can be brought into the channel which contains alignment means to accurately position the watercraft over the cradle. The cradle can thereby be lifted properly, moved to a storage rack location and accurately stored on the cantilever storage rack support beam assembly.

1. A watercraft cradle, for supporting a watercraft having a hull, a stern and a keel, the watercraft cradle comprising a base with a generally U-shaped horizontal framework having a central opening, a length, a plurality of support beams positioned along the length of the U-shaped horizontal framework, a keel block positioned at a stern end of the base and supported by the framework, and at least two platforms continuously extending from opposite of the stern end toward the stern end along at least about half of the length, each platform attached to at least one of the support beams, the central opening positioned horizontally along a majority of the length of the U-shaped horizontal framework, with at least one support beam and the at least two platforms positioned on either side of the framework central opening;at least one lateral frame piece positioned on the base to support the stern of the watercraft;at least two sides extending upward from the U-shaped horizontal framework, the sides positioned opposite the central opening and extending along substantially the entire length of the base; andsaid U-shaped horizontal framework is sized to accept and clear a cantilever storage rack support beam assembly in the central opening. 2. A watercraft storage system comprising the watercraft cradle of claim 1, means for raising, lowering and translating the cradle with a boat thereon, and a plurality of storage racks each having a cantilever storage rack support beam assembly extending therefrom for supporting a boat thereon. 3. The watercraft storage system of claim 2 wherein the means for raising, lowering and translating the cradle with a boat thereon include means to rotate the cradle with a boat thereon. 4. The watercraft storage system of claim 2, including a water-filled channel adjacent the plurality of storage racks, and means in the channel for guiding and locating a boat in the channel over a cradle submerged in the channel. 5. The watercraft storage system of claim 4 wherein the means in the channel move vertically in response to contact with a boat hull. 6. The watercraft storage system of claim 4 wherein the channel includes a catwalk over a portion of the channel, said catwalk being movable vertically and horizontally and having means for attachment to a boat hull. 7. The watercraft cradle of claim 1 wherein the at least two platforms include a plurality of cushioning devices positioned to support at least a portion of the watercraft hull. 8. The watercraft cradle of claim 7 wherein the plurality of cushioning devices are supported by means that can selectably be adjusted horizontally on the horizontal framework. 9. The watercraft cradle of claim 7 wherein the plurality of cushioning devices are supported by means that can selectably be adjusted rotatably relative to the horizontal framework. 10. A watercraft cradle, for supporting a watercraft having a hull, a stern and a keel, the watercraft cradle comprising a base with a generally U-shaped horizontal framework, the base having a length and a width and including:at least two support beams with each support beam positioned along the length of the base, the support beams defining a central opening positioned horizontally along a majority of the length of the base;a keel block positioned at a stern end of the base and supported by the framework;at least two platforms, each platform attached to one of the support beams and spaced from the other support beam across the central opening, the at least two platforms continuously extending from opposite of the stern end toward the stern end along at least about half of the length;at least one lateral frame piece positioned between and connecting the support beams, and spanning the width of the base;at least two sides extending upward from the base, the sides positioned opposite the central opening and extending along substantially the entire length of the base. 11. The watercraft cradle of claim 10, further including at least two pairs of support beams with each pair of support beams positioned on each side of the central opening. 12. The watercraft cradle of claim 10, further including at least two lateral frame pieces, each lateral frame piece positioned opposite the opening of the U-shaped horizontal framework. 13. The watercraft cradle of claim 10, wherein the U-shaped horizontal framework is sized to accept and clear a cantilever storage rack support beam assembly in the central opening.
