  The ABS Aerolight Navigathor is a French powered parachute and roadable aircraft that was designed and produced by ABS Aerolight of Sérignan-du-Comtat. Now out of production, when it was available the aircraft was supplied as a complete ready-to-fly-aircraft and as a kit for amateur construction.
  
  The company appears to have gone out of business in late 2007 and production ended.
  
  ## Design and development
  
  The Navigathor is a development of the earlier ATE, which stands for Air-Terre-Eau (English: Air-Land-Water) and indicates that the vehicle is capable of being used as a flying car with a top road speed of 150 km/h (93 mph) or as a boat with a top water speed of 7 km/h (4 mph).
  
  As an aircraft the Navigathor was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The aircraft has a maximum gross weight of 450 kg (992 lb). The aircraft carriage is built from a combination of metal tubing and composites and features a wedge-shaped boat hull. It features a 46 $m^2$ (500 sq ft) parachute-style wing, two-seats-in-tandem in an open cockpit, four-wheeled cross country all terrain vehicle style landing gear and a single 105 hp (78 kW) Hirth F-30 four-cylinder, horizontally opposed, two-stroke, aircraft engine, mounted in pusher configuration. In all modes the vehicle is powered by its ducted propeller.
  
  The vehicle has an empty weight of 230 kg (507 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 220 kg (485 lb). With full fuel of 35 litres (7.7 imp gal; 9.2 US gal) the payload is 195 kg (430 lb).
