A self powered or externally powered recreational and therapeutic aquatic device that will tow a person through and across a water surface, where in use, most of the persons body is essentially in the water, but where the head and arms are supported above the surface in a manner that could be described as a powered alternative to swimming but with a higher speed capability. The towing device and the person form an essentially single combined hydrodynamically streamlined shape that diverts or guides surrounding water underneath or around the persons chest area in a smooth flow. Steering is executed with the upper arms or shoulders, instead of the hands, and a variable stretching or extending force is applied to the persons torso and spine, controlled by the person.
