A floating dock including many buoyant wharf modules having approximately the same exterior size and shape, as well as density properties, relative to a pile extending through a vertically extending passage in one of the modules. The passage has four straight walls defining a square in the horizontal plane. A roller is at each corner of the square. The roller which is normally spaced from the cylindrical pile, contacts the pile as the dock bobs. A bracket mounted on a carrier having fixed tabs encased in a concrete deck of the module can be moved to different radial positions relative to the center, vertical axis of the passage, to accommodate different diameter piles. A permanent mold form for the concrete includes the lips extending upwardly from the passage side walls and lips extending upwardly from exterior side walls of a closed shell having foam therein. The shell has a roof forming the permanent mold form floor. The roof extends between the lips.
