1. A wind turbine comprising blades which extend outwardly from and sweep around a horizontal axis of rotation; a nacelle comprising at least a horizontal shaft driven by the blades and a drive train; an upright structure supporting the nacelle and blades, the upright structure extending below the sweep of the blades, and a generally horizontal floating base supporting the upright structure, wherein,
the upright structure comprises a pivot supporting the nacelle, and
the wind turbine further comprises an elongate vertical element supported by the pivot, the elongate vertical element being connected to the nacelle for movement with the nacelle, the elongate vertical element carrying a weight, the weight maintaining the axis of rotation of the blades in a horizontal position as the floating base pitches, the pivot being located downwind of the blades and upwind of the elongate vertical element.
