A pivoting sailing rig adapted for use on a vehicle, such as a watercraft, includes a frame with spaced apart primary shafts which are oriented to rotate about and move axially along axes which are generally parallel to the center line or fore-aft axis of the watercraft. Wing sails are mounted on coupling elements secured to the primary shafts and are connected to rigging for rotating the wing sails about their longitudinal axes to vary the angle of attack, respectively. The primary shafts include control arms and rigging for rotating the primary shafts between substantially upright positions of the wing sails and laterally declined and reefed positions of the wing sails. The wing sails may include solar collectors mounted thereon and may be oriented in use to take advantage of wind as well as sunlight conditions to optimize sailing as well as energy collection. |
