Abstract
Abstract A removable pier having at least two sections pivotably joined end to end and extending from a footing on a shore into a body of water. The pier sections are removably supported on permanent footings for stability. Booms having cable guides are removably mounted on leg extensions of the inner pier section. Cables, driven by winches, pass through the cable guides on the boom and engage the outer pier section for its removal from the water by rotation about its pivotable connection with the inner pier section. The booms are transferred to mounts on the shore at the sides of the pier for removal of the inner pier section from the water with the outer pier section in overlying position. The outer pier section is preferably slightly shorter than the inner pier section so that both pier sections can be stored in upright position on the shore ready for repositioning in the water.
