This educational video is shows the Boeing built hydrofoils named after Tucumcari, New Mexico, the design basis for the technology used in the subsequent United States Pegasus-class patrol boats and the Jet-foil ferries. Its unique feature was a water-jet propulsion and a computer-controlled fully submerged foil configuration of one foil at the bow and foils on the port and starboard sides. The Tucumcari was one of two prototype boats contred by the Navy for the purpose of evaluating the latest hydrofoil technology with a fast top speed of 50 knots. The second boat was the rival Grumman built USS Flagstaff (PGH-1).
