Mariner Aircraft Mariner
The Mariner Aircraft Mariner is an American ultralight amphibious flying boat that was designed by Larry Seifert and produced by Mariner Aircraft, starting in 1989. The aircraft was supplied as a kit for amateur construction. Design and development
The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of  plus floats. In its monoplane single seat version the aircraft has a standard empty weight of . Many were registered as amateur-builts rather than ultralights. It features a multiple wing arrangement, a single-seat, open cockpit, re-positionable conventional landing gear and a single engine in pusher configuration. The aircraft is made from sheet aluminum, aluminum tubing and aircraft fabric, with a plywood hull. The aircraft was sold in three different models. The first is a biplane design, with a pusher engine mounted between the wings. Engines used include the  Rotax 447,  Rotax 503 and  Rotax 582 and  Subaru EA-81. The top wing of the biplane was removed and the lower wing increased in span to create a low-wing monoplane version, available in single and two seat versions. The final model mounts the top wing only in parasol wing configuration and features two seats in tandem. The company went out of business in the early 1990s after only a few years of production.
