The HYDRA TERRA vehicle, manufactured by Cool Amphibious Manufacturers International (C.A.M.I.), is a newly fabricated amphibious vehicle designed from the wheels/keel up to provide a safe and comfortable ride for passengers in both highway and marine environments. The vehicle is 39 feet long with a beam (width) of 8.5 feet. It has a capacity of 46 passengers and 2 crew. The passenger compartment has bench style padded seats - two persons per side and four per row. Personal Flotation Devices (PFDs) are stowed beneath each seat and child-size PFDs are available on board. In the marine mode, the vehicle has the greatest freeboard of any amphibian operating today. The passenger compartment is fully covered with lightweight clear poly carbonate sheeting. The sides are open for maximum viewing. Passengers enter through a door via a permanently mounted ladder.

The hull is constructed to American Bureau of Shipping (ABS) standards. The unique design of the HYDRA TERRA provides the vehicle/vessel with a positive displacement foam flotation system. The side sections of the 100 percent aluminum hull are divided into small compartments and filled with foam material that is approved by the Unites States Coast Guard. The control station for the HYDRA TERRA is the cab section of a Ford F-Series truck. The HYDRA TERRA is powered by a Caterpillar 210 hp 7.1 litre Turbo Diesel engine. The vehicle has heavy-duty disc brakes with a six-wheel anti-lock computer brake control system. The marine drive is a live transom mounted stern drive with an engageable propeller designed for diesel applications.
