Design and development.
The aircraft has a standard empty weight of . It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem, open cockpit, a hull made from an inflatable boat and a single engine in pusher configuration.
The aircraft is made from bolted-together aluminum tubing, with its large area single surface wing covered in Dacron sailcloth. Its span wing is supported by a single tube-type kingpost and uses an "A" frame control bar. An off-the-shelf commercial inflatable boat hull is used. A water rudder is fitted at the rear of the boat hull. The standard engine supplied was the twin cylinder, two-stroke, liquid-cooled Rotax 582 of , including an electric starter.
The large wing area was employed to keep the stall speed low to avoid porpoising problems while conducting water operations. The weight shift nature of the wing means that hull pitch angle cannot be controlled and loss of control is a risk when higher take-off and landing speeds are required.
The Sky-Tender was assembled in the United States by Personal Flight from aircraft and marine components from Italy, France and Austria. The price in 2000 was US$20,000.
