Design and development

The Seastar is a parasol wing flying boat, with its two engines mounted in a single nacelle over the wings in a push-pull configuration. In general layout, it strongly resembles Dornier's Do 18 of the 1930s.

The first prototype, a proof-of-concept aircraft using the metal wings from a Dornier Do 28 and with large struts bracing the wing to the sponsons, made its maiden flight from Hamburg on 17 August 1984.[1] The second prototype, representing the definitive design was larger, and featured a new, unbraced composite wing. It first flew from Oberpfaffenhofen on 24 April 1987.[1]

In October 2009, Dornier Seaplane announced that it would launch production of the Seastar.[2]

In May 2010, Dornier Seaplane announced that it would build the Seastar in Saint-Jean-sur-Richelieu, about half an hour away from Montreal, Quebec, Canada. [3]
