ABSTRACT:
A plurality of relatively narrow finger piers project perpendicularly from mainwalk floats at spaced-apart locations. The finger piers are secured to the floats in cantilever fashion using a variety of fastening structures. Since loads carried by the finger pier are not supported by the buoyancy of the pier, the width and thickness of the pier can be substantially less than comparable floating finger piers. In one embodiment the pier is principally formed by a triangular frame which is secured to the mainwalk floats by either a mounting bracket or rods extending transversely through the mainwalk floats and longitudinally through upper corner pipes of the triangular frame. A deck is then fastened across the upper pipes. The vertical angle of each pier may be adjusted by rotating an adjusting nut which abuts the lower pipe of the triangular frame. In a second embodiment pairs of parallel beams are secured to the mainwalk floats by a bracket, and a deck is mounted on the upper surface of the beams. Spreader timbers or a buoyant foam may be mounted between the beams beneath the deck.
