A buoyant energy converting apparatus comprises: a wind energy converter, eg a wind turbine 12 or kite system, supported by a rigid framework connection member 16 on a buoyant platform 14. The buoyant platform 14 may comprise a planar rectangular lattice framework 24 having a float 26 at each corner. The connection member 16 may comprise a lattice framework forming a rectangular frustrum. Wave energy converters 42, eg each comprising an energy capturing float 38, are provided eg on the upper surface of the buoyant platform 14. In the in-use configuration (fig.3) the buoyant platform 14 is submerged in the body of water with the connection member 16 protruding from the surface of the body of water such that the wind energy converter 12 is not in contact with the body of water and with the floats 38 near the water surface. In a storm configuration (fig.4), the floats are held adjacent the platform 14. The apparatus aims to provide increased stability in stormy conditions, a more consistent supply of power and improved levelised cost.
