 Y2Fly-Seahawk
 
The Y2Fly Seahawk is an American amphibious flying boat ultralight trike that was designed and produced by Y2Fly of Point Harbor, North Carolina.
 
The Seahawk features a cable-braced hang glider-style high wing, weight-shift controls, a two-seats-in-tandem, open cockpit, a trimaran hull and a single engine in pusher configuration.
 
The aircraft hull is made from fiberglass, with stainless steel fittings. The wing and its supporting structure are made from bolted-together aluminum tubing, with the single surface wing covered in Dacron sailcloth and supported by a single tube-type kingpost. The Seahawk uses an "A" frame control bar for weight-shift control. The hull was carefully designed to account for the inherent lack of pitch control that trikes have while on the water. It was designed to reduce porpoising and water spray being thrown into the crew seats and propeller. The hull also provides lift in flight and allows flight at reduced power and fuel consumption. The retractable landing gear is of tricycle configuration and is mechanically retracted by a lever located next to the pilot. The nosewheel retracts in front of the bow of the hull, while the main landing gear retracts beside the tri-hull. The standard powerplant supplied was the twin cylinder, two-stroke, liquid-cooled 64 hp (48 kW) Rotax 582 aircraft engine.
 
A clutch system is standard on the 582 Rotax using an E box. This allows pilots to safely taxi in the water, without having the prop pushing the craft along. Another feature is a full time water rudder located at the rear and center of the craft. The unit is equipped with all three wheels retractable, actuated by one manual lever.
 
The "trimaran float design" uses spray rails, and splash pans. "Dive planes" help bring the nose of the craft up in case of slight nose down landing, or taxing in rough water. The use of fiberglass and stainless steel components allow the Sea Hawk to be used in salt water.
 
The Sea Hawk uses a 16.8 meter, certified Wizard wing to give the best performance for take-off and cruise. With two on board the craft stalls at 30 mph and cruises along at 55 mph. 
 
The empty weight of this amphibious trike without wing is 341-363 lbs. depending on what engine is chosen. The aircraft was supplied as a completed aircraft but production has ended.
