A shape shifting foil alters the shape of a fluid foil contour by rotating a leading edge structure. A skin that forms the fluid foil contour is at least partially attached to the leading edge structure, and is wrapped around the leading edge structure so two edges of the skin form the trailing edge of the fluid foil. The two edges forming the trailing edge slide with respect to one another, thereby permitting the skin to shift when the leading edge structure is rotated.
