ABSTRACT:
A barge for replacing foam blocks that support floating docks. The barge is provided with a float sinker that removably attaches to the barge via a boom. The float sinker can be moved from side to side via the boom and can be rotated. The float sinker has clamp arms with movable flat plates for releasably grasping foam blocks. The float sinker has hollow chambers that can be flooded as a means of pulling the blocks downward in the water and has means for expelling the water from the chambers to allow the blocks to rise to the surface of the water. Controls are provided on the deck of the barge for operating the barge and for remotely operating the float sinker from the barge.
