Abstract: A buoy for supporting a cable which is connectible with an anchor, includes at least two buoyancy chambers which can be filled with a flotation medium, one of the buoyancy chambers having a closable inlet and outlet through which fluid can be passed to vary as desired the volume of a flotation medium in the one chamber. The buoy preferably includes a system for guiding the cable and a buoyancy chamber is preferably so mounted on the cable-guiding system as to be longitudinally movable relative thereto, at least one roller assembly being mounted on the cable-guiding system, and including a plurality of freely rotatable rollers which define an opening for passage of a cable therethrough in a substantially friction free manner. The cable-guiding system preferably comprises a plate having a central opening for passage of the cable and normal to one major surface of which are mounted pairs of parallel cheek plates equally spaced to each side of and parallel to the radiating sections of criss-crossed planes intersecting along an axis normal to and centred on the plate, and rollers mounted on roller shafts supported between the cheek plates of each pair, the axes of the roller shafts being so located and the diameters of the rollers being such that the rollers define a central opening axially aligned with that through the plate and through which the cable can pass.
