The aircraft is supplied as a kit for [[Homebuilt aircraft|amateur construction]] or as a complete ready-to-fly-aircraft.<ref name="WDLA11">Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 220.

==Design and development== The Trident was designed to comply with the [[Fédération Aéronautique Internationale]] [[microlight]] category, including the category's maximum gross weight of {{convert|450|kg|lb|0|abbr=on}}. The Trident features a [[strut-braced]] [[hang glider]]-style [[high-wing]], weight-shift controls, a two-seats-in-[[tandem]] open cockpit with a rigid boat hull, retractable [[tricycle landing gear]] and a single engine in [[pusher configuration]].<ref name="WDLA11" />

The aircraft is made from bolted-together [[aluminum]] tubing, with its double surface wing covered in [[Dacron]] sailcloth and its boat hull made from either [[fibreglass]] or [[carbon fibre]] and [[Kevlar]]. Its {{convert|10.5|m|ft|1|abbr=on}} span Hazard wing has struts and uses an "A" frame weight-shift control bar. The powerplant is a twin cylinder, liquid-cooled, [[two-stroke]], [[dual-ignition]] {{convert|64|hp|kW|0|abbr=on}} [[Rotax 582]] engine or a four-cylinder, air and liquid-cooled, [[four-stroke]], [[dual-ignition]] {{convert|80|hp|kW|0|abbr=on}} [[Rotax 912UL]] engine or a {{convert|78|hp|kW|0|abbr=on}} converted [[Smart Car]] four stroke [[turbocharged]] engine. All engines are fitted with a clutch that stops the propeller from turning when the engine is at idle to permit water handling. The boat hull features a water [[rudder]].<ref name="WDLA11" />

Starting in 2005 the frame and wing portion of the aircraft was taken from the [[Skyrider Sonic]] ultralight trike, built by [[Skyrider Flugschule]].<ref name="WDLA11" />

==Variants== ;Hydro :Initial [[flying boat]] model that lacks wheeled landing gear. Introduced in 1998 and in production in 2013.<ref name="WDLA11" /> ;Trident :Amphibious model with fibreglass boat hull, in production in 2013.<ref name="WDLA11" /> ;C :Amphibious model with carbon fibre/Kevlar boat hull and [[lexan]] windows in the bottom of the hull to allow visibility downwards. In production in 2013.<ref name="WDLA11" />
