Sea and Sky Cygnet

The Sea and Sky Cygnet (also known as the Krucker Cygnet) is an American amphibious ultralight trike that was designed by J.P. Krucker and initially produced by his company Krucker Manufacturing in Sudbury, Ontario, Canada and later by Sea and Sky of Fort Walton Beach, Florida, United States. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.

Design and development
The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category and the US light-sport aircraft rules. It features a strut-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, retractable wheeled tricycle landing gear and dual floats and a single engine in pusher configuration.

The aircraft is made from bolted-together aluminum tubing, with its single surface wing covered in Dacron sailcloth. Its 10.3 m span wing is supported by struts and uses an "A" frame weight-shift control bar. The standard powerplants are the twin cylinder, liquid-cooled, two-stroke, dual-ignition 65 hp Rotax 582 engine, the four cylinder, air and liquid-cooled, four-stroke, dual-ignition 80 hp Rotax 912UL and the 100 hp Rotax 912ULS engines. The aircraft has an empty weight of 529 lb and a gross weight of 992 lb, giving a useful load of 463 lb. With full fuel of 10 u.s.gal the payload is 403 lb.

A number of different wings can be fitted to the basic carriage, including the North Wings Pulse 17 m2 and 19 m2 sizes. The LSA-approved wings are the North Wing Mustang 3 in 15 m2, 17 m2 and 19 m2 and the Keitek Hazard.
