A transparent modulatable kayak with shading system includes two pairs of fitting devices, reversibly connecting multiple kayaks. The tubular body of the paddle is reversibly divisible at the center. The inner volume of the hull has a container housing a cloth adapted to shade the user on the seat. The upper surface of the hull has a plurality of recesses, of which at least one pair is positioned at the bow and at least one pair is positioned at the stern, each housing a portion of the tubular body of the paddle. The tubular body includes, at each end, at least one coupling device adapted to reversibly connect at least one of the corresponding coupling devices of the cloth. The hull is made of any natural or synthetic polymer adapted to ensure the floating of the kayak and its total transparency.
