The aircraft was supplied as a completed aircraft.<ref name="Cliche">Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page C-23.

==Design and development== The Seahawk features a choice of wings [[Flying wires|cable-braced]] [[hang glider]]-style [[high wing]], weight-shift controls, a two-seats-in-[[tandem]], open cockpit, a [[trimaran]] hull which was designed and built in Italy and a single engine in [[pusher configuration]].<ref name="Cliche" />

The most comprehensive book written about trikes and flight training, including how to fly the Seahawk, is "Trikes, The Flex-Wing Flyers, available from Lucian Bartosik Cost is $30 for the 265 page book. 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 gear|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 {{convert|64|hp|kW|0|abbr=on}} [[Rotax 582]] [[aircraft engine]].<ref name="Cliche" /> <!-- ==Operational history== --> <!-- ==Variants== --> <!-- ==Aircraft on display== -->
