Definition
Seamax Aircraft is an Australian manufacturer of light‑sport amphibious aircraft, best known for producing the Seamax M‑22, a two‑seat, high‑wing monoplane capable of operating from both land runways and water surfaces.
Overview
Founded in the mid‑2000s, Seamax Aircraft Ltd. is headquartered in Hervey Bay, Queensland, Australia. The company focuses on designing, certifying, and marketing light‑sport aircraft that meet the standards set by aviation authorities such as the United States Federal Aviation Administration (FAA) and the Australian Civil Aviation Safety Authority (CASA). Its primary product, the Seamax M‑22, is marketed for recreational flying, flight training, and utility roles such as aerial observation and light cargo transport. The aircraft is sold both as a factory‑built unit and as a kit for amateur construction, depending on the regulatory framework of the purchaser’s country.
Etymology/Origin
The name “Seamax” combines the words “sea” and “max,” suggesting maximum capability for operations on water. The term is a brand name created by the company and does not derive from a historic or linguistic source beyond this commercial usage.
Characteristics
- Design: High‑wing, single‑engine monoplane with a tractor‑propeller configuration. The airframe is primarily constructed from composite materials, providing a balance of strength and light weight. Retractable tricycle landing gear allows transition between land and water operations.
- Capacity: Two seats in side‑by‑side configuration, with provisions for limited baggage.
- Powerplant: Typically equipped with a Rotax 912ULS four‑cylinder, four‑stroke engine delivering 100 hp, though alternative engines may be approved under different certification regimes.
- Performance (as published by the manufacturer):
- Cruise speed: approximately 115–120 kt (215–222 km/h).
- Maximum range: about 800 km (432 nm) with standard fuel tanks.
- Service ceiling: around 10 000 ft (3 050 m) mean sea level.
- Take‑off distance on water: roughly 300 ft (90 m) under standard conditions.
- Certification: Certified under Light‑Sport Aircraft (LSA) rules in the United States and similar categories in Australia and Europe, meeting applicable airworthiness standards for amateur‑built and factory‑built aircraft.
- Operational Use: Employed for personal recreation, pilot training—including amphibious‑operation training—and light utility missions such as environmental monitoring, fisheries patrol, and coastal tourism.
