A tip structure 20 for an aerofoil 12 is disclosed. The winglet 20 comprises a pressure side structure 50 arranged on a pressure side 43 of the blade 12, and a suction side structure 60 arranged on a suction side 44. The pressure side and suction side structures have different pitch angles so that the chord of the pressure side structure extends forwardly in the direction of motion and relatively more radially outwardly away from the blade root, or less radially inwardly towardsthe blade root, than the chord of the suction side structure, such that there is a winglet relative twist angle between the two structures. The invention extends to a rotor, a wind turbine a wind farm, a helicopter, an aircraft and a method of improving the mass efficiency of a rotor.
