The Panther's adventurous appearance incorporates a durable light weight fiberglass body/ hull, and is a next generation off road chromoly chassis built to hold up to extreme pounding abuse on land or in water. Not only is the body/hull extraordinarily strong, it is filled with 32 cubic feet of US Coast Guard approved closed cell styrofoam making it virtually unsinkable.
There are two parts to the equation of why WaterCar has revolutionized amphibious construction forever. The first part is the hull. WaterCar has built and tested over a hundred hull bottom designs. The finest naval architects from different parts of the world have all contributed to the Panther design. The second is the chassis structure, modern day automotive technologies have been slow to develop compared to aircraft and aeronautical technology. However, recent pressures on the automotive engineers to make "faster, lighter, stronger" advanced composite construction has flooded automotive industry with new technology. WaterCar has incorporated the newest and best of this technology to create one of the most state of the art hull and chassis designs.
