Abstract: A collapsible catamaran has twin rigid hulls attached by frame members to a platform that holds a rider. The hulls and platform are divided into sections to allow the hulls and platform to be disassembled and transported in a small space. The hulls are substantially hollow and have access ports that allow a rider to store buoyant materials or equipment inside the hulls. A motor mount is attached to the front platform and receives an electric motor that is configured to pull the catamaran through the water. A cover may be attached to the platform to provide shade to the rider. The cover may support one or more solar panels that collect electricity to power the motor. The parts may be combined in a kit, which allows the rider to assemble the components of the collapsible catamaran. The catamaran may then be assembled from and disassembled into the components before and after each use.
