Design and development

The Seamax M-22 was designed in 1999. A prototype was flown in 2000 and the first production aircraft left the factory in 2001. The Seamax M-22 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 1000NaN0 Rotax 912ULS pusher configuration engine mounted above the wing to avoid water ingestion.^[3]

Versions can be constructed to meet the requirements of both the European microlight and US LSA categories.^[4] A version with folding wings is available as the M-22 FW.^[5]

A total of 160 had been built by 2018.
