The cradle assembly comprises a plurality of horizontally varying cradle beams, a cradle wall extending upward from the cradle beams and a transportation track traversing the cradle beams. A transportation rail is slideably positioned on the transportation track to engage the bottom of the water craft as the cradle assembly moves the watercraft with respect to the support module. A positioning system is operatively connected to the transportation rail to extend a substantial portion of the transportation rail within the support module to place the watercraft in and retrieve it from the support module. ## Claims ### Claim 1 A cradle assembly for moving and positioning a watercraft with respect to a support module in a watercraft storage assembly, the watercraft including a bottom, the cradle assembly comprising a plurality of cradle beams; at least one cradle wall vertically extending upward from one of the cradle beams; at least one transportation track traversing the cradle beams; a transportation rail slidably positioned on the transportation track to engage the bottom of the watercraft as the cradle assembly moves the watercraft with respect to the support module; and a positioning system operatively connected to the transportation rail to extend a substantial portion of the transportation rail within the support module. ### Claim 2 (depends on 1) The cradle assembly of claim 1, further including a padded support operatively attached to the transportation rail opposite the transportation track. ### Claim 3 (depends on 1) The cradle assembly of claim 1, further including a cradle clamp positioned on the cradle wall to selectively engage the support module during movement of the watercraft relative to the support module and restrict horizontal movement of the cradle assembly relative to the support module. ### Claim 4 (depends on 3) The cradle assembly of claim 3, the cradle clamp further including an actuating arm positioned to engage the transportation rail to engage the cradle clamp to the support module after activation of the transportation rail. ### Claim 5 (depends on 3) The cradle assembly of claim 3, wherein the cradle clamp includes: a bottom brace pivotally attached to the cradle assembly and positioned proximate to one of the cradle beams; and a top brace positioned on the cradle wall opposite the cradle beam. ### Claim 6 (depends on 5) The cradle assembly of claim 5, wherein the top and bottom braces each include at least one friction reducing device positioned to engage the support module and allow vertical movement of the cradle assembly relative to the support module. ### Claim 7 (depends on 1) The cradle assembly of claim 1, wherein the positioning system includes a drive sprocket and chain positioned under the transportation rail. ### Claim 8 (depends on 1) The cradle assembly of claim 1, the transportation rail further including at least one securing bracket fixed to the transportation rail and slidably engaging the transportation track, the securing bracket restricting vertical movement of the transportation rail with respect to the transportation track. ### Claim 9 (depends on 1) The cradle assembly of claim 1, wherein the cradle beams are horizontally adjustable. ### Claim 10 (depends on 9) The cradle assembly of claim 9, each cradle beam including first second and middle sections, wherein the first and second sections horizontally extend with respect to the middle section. ### Claim 11 (depends on 9) The cradle assembly of claim 9, wherein: further including: a cradle beam adjustment system positioned to control the horizontal adjustment of the cradle beams; and a first and second transportation track; the watercraft includes a width, and the cradle beam adjustment system selectively spaces the transportation tracks from each other a width less than the width of the watercraft. ### Claim 12 A cradle assembly for moving and positioning a watercraft with respect to a support module in a watercraft storage assembly, the watercraft including a bottom and a width, the cradle assembly comprising a plurality of horizontally adjustable cradle beams, each cradle beam including a left and a right side; a cradle wall vertically extending upward from each side of the cradle beam; first and second transportation tracks traversing the cradle beams substantially parallel to the cradle walls; and a transportation rail positioned on each transportation track to engage the bottom of the watercraft as the cradle assembly moves the watercraft with respect to the support module. ### Claim 13 (depends on 12) The cradle assembly of claim 12, each cradle beam including a middle section, wherein the left and right sides horizontally extend with respect to the middle section. ### Claim 14 (depends on 12) The cradle assembly of claim 12, further including a cradle beam adjustment system positioned to control the horizontal adjustment of the cradle beams, wherein the cradle beam adjustment system selectively spaces the transportation tracks from each other a width less than the width of the watercraft. ### Claim 15 (depends on 12) The cradle assembly of claim 12, wherein the transportation rails are slidably positioned on the transportation tracks to horizontally vary the watercraft with respect to the cradle beams and the support module. ### Claim 16 (depends on 15) The cradle assembly of claim 15, further including a positioning system operatively connected to the transportation rails to extend a substantial portion of the transportation rails within the support module. ### Claim 17 (depends on 12) The cradle assembly of claim 12, further including a cradle clamp positioned on the cradle wall to selective engage the support module during movement of the watercraft relative to the support module. ### Claim 18 (depends on 17) The cradle assembly of claim 17, the cradle clamp further a bottom brace pivotally attached to the cradle assembly and positioned proximate to one of the cradle beams; a top brace positioned on the cradle wall opposite the cradle beam; and the bottom brace including an actuating arm responsive to movement of the transportation rail to engage the bottom brace to the support module. ### Claim 19 (depends on 18) The cradle assembly of claim 18, wherein each brace includes a friction reducing device positioned to engage the support module and allow vertical movement of the cradle assembly relative to the support module. ### Claim 20 A cradle assembly for use in a watercraft storage system including a support wall, at least two watercraft support modules mounted and stacked in relationship to said support wall, the watercraft including a bottom and a width, the cradle assembly comprising: a plurality of horizontally adjustable cradle beams, each cradle beam including a left and a right side; a cradle wall vertically extending upward from each side of the cradle beam; first and second transportation tracks traversing the cradle beams substantially parallel to the cradle walls; a transportation rail slidably positioned on each transportation track to engage the bottom of the watercraft as the cradle assembly moves the watercraft with respect to the support module; a positioning system operatively connected to the transportation rail to extend a substantial portion of the transportation rail within the support module; a cradle beam adjustment system positioned to control the horizontal adjustment of the cradle beams and selectively horizontally space the transportation tracks relative to each other; a cradle clamp positioned on each cradle wall to selectively engage the support module during movement of the watercraft relative to the support module and restrict horizontal movement of the cradle assembly relative to the support module when engaged.
