An offshore floating support, comprising a submersible base extending from which is an elongate tower riser 14 for supporting a wind turbine, the base including two or more independent enclosures 16 adapted to provide buoyancy to the support when the base is submerged; and two or more external platforms 18 each located between an adjacent pair of the independent enclosures and adapted to receive and retain ballast thereon. Preferably the enclosures and external platforms have a substantially wedge-shaped footprint increasing in width with increasing radial distance from the central axis, and are disposed in a circular array about the central axis. There may be a ballast distribution system, such as a pump, operable to manage ballast levels within the two or more enclosures. A wave deflection system may comprise one or more deflector plates extending from the tower riser, and a current deflection system may be defined by profiled edges on the base.
