About the Aero Adventure Aventura II

The Aero Adventure Aventura II is an American-built amphibious light sport aircraft that brought affordable water operations to the recreational flying market starting in the early 2000s. Designed as a high-wing pusher configuration with a single piston engine mounted above the cabin, the Aventura II qualifies under U.S. Light Sport Aircraft rules with a maximum takeoff weight of 1,320 pounds, making it accessible to sport pilots without requiring a full private pilot certificate.

Its fiberglass hull and retractable landing gear allow operations from both conventional runways and water, a versatility rare in the LSA category. The type cruises around 80 knots with a never-exceed speed of 120 knots, and its low stall speed of 35 knots in landing configuration makes it forgiving for water touchdowns and short-field operations. While not a speed demon, the Aventura II carved out a niche among pilots seeking an economical amphibian for backcountry lakes and coastal exploration.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
