Cool Amphibious Manufacturers International (CAMI) is an amphibious vehicle manufacturer based in Bluffton, South Carolina in the United States. They have many different types of amphibious vehicles, including the Hydra Terra, an amphibious bus filled with foam. CAMI claims that the bus is unsinkable and safer than the DUKW (World War II amphibious assault vehicles), LARCs (Vietnam War era assault vehicles), and the British FV620 Stalwart amphibious load carrier.
The Hydra Terra vehicle is currently used by major cities around the world in what are termed Splash, or Duck Tours. Some of the international cities offering these tours include Boston, Dublin and Belfast.
A similar Splash Tour in Rotterdam uses a competing amphibious bus produced by the Dutch company DAT BV.
