Design and development

The SeaMax was designed in 1999. A prototype was flown in 2000 and the first production aircraft left the factory in 2001. The SeaMax is constructed using composite materials and metal components. It has a two-seat, side-by-side configuration cabin with a bubble canopy which is hydraulically raised for access. The high-wing is strut-braced and the tail is a cruciform tail. The aircraft's tricycle landing gear is retractable for landing on water. It is powered by a 100 hp (75 kW) Rotax 912ULS pusher configuration engine mounted above the wing to avoid water ingestion.^[1]
