A one-person watercraft, with a unique design and basic innovative modular catamaran style structure that makes the craft transformable, and useful for different hybrid water sports. The watercraft enables the user to either stand or sit while providing power to the craft. The craft comes in multiple versions, and the user may provide power to the craft through elliptical movement, hand-driven levers or foot-driven pedals/skis while standing up and/or sitting down and moving in an elliptical motion. These turn a propeller, at the back of the craft. Embodiments of the craft utilize the Venturi effect (with a flexible drive shaft and a retractable propeller rudder system) to increase the propulsion created by water flowing through the propeller. The craft is designed to float stably to ensure users' safety, and may be used for leisure recreational activity, exercise, physical rehabilitation, transportation to travel across water, or any combination of the above.
