The Sealoon is derived from the earlier biplane AAC SeaStar and features a cantilever mid-wing, two seats in side-by-side configuration in an enclosed cockpit that is 440NaN0 wide, retractable tricycle landing gear and a single pod-mounted engine in pusher configuration.
The aircraft is made from composites and aluminium with aircraft fabric covering. Its 30.31NaN1 span wing has an area of 196square feet. The aircraft's recommended engine power range is 80to and standard engines used include the 1000NaN0 Rotax 912ULS four-stroke powerplant. Construction time from the supplied kit is estimated as 1000 hours.
The company CEO, Hans Schaer, indicated in June 2010 that development of the Sealoon was being delayed by the ongoing Great Recession.[2]
