ABSTRACT:
A device for mooring and attaching watercrafts such as sailboats, rowboats, speedboats and the like is disclosed. A preferred embodiment includes an outer cylinder fixably secured to an axial threaded rod through a central anchor. Opposing springs are positioned on opposite sides of the central anchor. The outer cylinder contains two inner tubes each having one end within the outer cylinder and the other end extending outside the outer cylinder. The exposed ends of the inner cylinders are attached by rotatable connectors to a watercraft and dock respectively. Each inner cylinder has their own inner spring which are positioned on extreme sides of fixed anchors within the inner cylinders. The threaded rod uses locker nuts and washers to hold all the components together by axially passing through all the springs, anchors and cylinders. During operation, the springs within the outer cylinder compress in equal increments towards one another and expand in equal increments when the water craft moves away from the dock. The springs within the inner cylinders compress equally and simultaneously when the watercraft continues to move away from the dock. Likewise, these springs return to their normal position when the watercraft moves back towards the dock. Various pivotable attachments allow the watercraft to move 45 degrees up and down and side by side depending upon drift, wave action and the like.
