Abstract: An adjustable frame device for a profiled sail device includes a fixed luff-sided first frame portion and a leech-sided second frame portion. The second frame portion includes a first flexible sail batten and a second flexible sail batten that are movable with respect to one another in a sail-batten longitudinal direction to adjust the frame device, with one of the sail battens serving as a compression batten and the other of the sail battens serving as a tension batten. An adjustable profiled sail device includes a first profiled surface against which air can flow, a second profiled surface against which air can flow, with the first profiled surface and the second profiled surface being spaced apart from one another, and an adjustable skeleton device disposed between the profiled surfaces. The skeleton device includes at least one adjustable frame device.

Abstract: A frame device (200) for a profiled sail device, the frame device (200) having at least one adjustable frame element (202), the at least one adjustable frame element (202) having longitudinal struts which are spaced apart from one another and are assigned to sail surfaces which are spaced apart from one another, and transverse struts which extend between the longitudinal struts, characterized in that the longitudinal struts and the transverse struts delimit quadrangles which each have two diagonals with varying lengths depending on the adjustment, and the diagonals each have a predetermined maximum length, and a profiled sail device having sail surfaces which are spaced apart from one another and against which the flow can impinge and which form profiled surfaces, a sail front edge and an adjustable skeleton device arranged between the sail surfaces. The skeleton device has at least one frame device (200) of this type.

Abstract: A frame device for a profiled sail device. At least one frame element has a first profile contour that corresponds to one sail surface and a second profile contour that corresponds to another sail surface. The frame device has a profile contour with at least one profile contour section which is formed by a profile contour of the frame element, and the frame device can be adjusted between a first operating position and a second operating position. In a first operating position the first profile contour forms a contour section for the first sail surface or for the second sail surface, and the second profile contour does not form a profile contour section; and in the second operating position, the first profile contour does not form a profile contour section of the frame device for the sail surface, and the second profile contour forms at least one profile contour section of the frame device for the respective other sail surface.
