Aspects of an embodiment of a check valve turbine assembly include a rotation platform having an axis of rotation, a vertical member concentrically secured to the rotation platform about the axis of rotation, a rotatable sail assembly attached to the vertical member that includes a frame, a hinge beam, and a rotatable sub-sail assembly. The sub-sail assembly includes a stem beam, a sub-sail grid frame attached to the stem beam, and a plurality of flaps rotatably attached to the sub-sail grid frame and configured to move between a closed position and an open position relative to the sub frame. Aspects of a marine check valve turbine include a free-floating platform structure configured with an upper surface at or near a water surface and a vertical member secured to the platform structure about an axis of rotation and configured to extend from the upper surface of the platform structure.
