[1] The Fregat-Hydro was designed to comply with the Fédération Aéronautique Internationale microlight category.
It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, twin inflatable floats and a single engine in pusher configuration.
[1] The Fregat-Hydro is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth.
Its 9.28 m (30.4 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar.
On the more recent models the powerplant is a modified liquid-cooled, four-stroke, 80 hp (60 kW) Suzuki automotive engine.
