Abstract

The present invention provides a novel multiple-seat wagon propelled by simultaneously rowing and pedaling for use in water or land. The present invention provides a unique and versatile multiple-seat wagon that can be converted into a sea vessel. It allows the vehicle to float on water and serves as the lower part of the vessel. The water propulsion assembly includes two water wheels that are responsible for generating forward and backward motion when the vehicle is in water. It also has a water shaft that holds the water wheels. The pinion gear increases the rotational speed of the water wheels, enhancing the efficiency of propulsion from a pedaling motion and a rowing motion. The invention features a demountable coupling system that allows for disassembly and reassembly while maintaining the interconnection of its components.
