1. A power generating apparatus for extracting energy from flowing water, comprising:
a buoyancy vessel, and a turbine assembly coupled to the buoyancy vessel;
the turbine assembly comprising a turbine rotor mounted to a nacelle, and a support structure;
the support structure being coupled at its inboard end to the buoyancy vessel and at its outboard end to the nacelle;
the turbine assembly being pivotally moveable between a first position and a second position;
wherein, when the power generating apparatus is floating on a body of water;
in the first position the turbine assembly extends below the buoyancy vessel and the nacelle is fully submerged below the water surface; and
in the second position the turbine assembly extends to a distance greater than a length of a rotor blade away from and generally to the side of the buoyancy vessel and a part of the nacelle projects above the water surface.
