Abstract
A configuration for a sailboat mainsail comprises a rotating wind-mill like sail structure mounted on a rotating pedestal base. The wind driven rotating sail delivers power to the sailboat propeller through a flexible driveshaft and transmission and thus provides an ability to sail a particular desired course direction irrespective of the direction from which the wind is blowing.
