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 ...
[ What is claimed is:] [1.] A vehicle including a wing sail pivotable at its base about a reefing axis parallel to the fore-aft axis of the vehicle whereby the wing sail can be reefed between a substantially upright position and a substantially horizontal position, the vehicle including reefing means for controlling the reefing of the wing sail relative to the vehicle about the fore-aft axis, the wing sail including solar collecting means and defining a longitudinal axis and being rotatable about its longitudinal axis whereby the wing sail can be feather...
