Gweduck Aircraft

The Gweduck is an experimental, twin engine flying-boat style amphibian of composite construction and is reminiscent of the Grumman style aircraft. Aircraft development started in the early 1990's and has focused on a broad range of issues including aircraft performance and handling as well as manufacturing technologies.

The Gweduck design project was started as an attempt to build a composite Widgeon - To eliminate the extensive corrosion and maintenance problems so common to the 40+ year old design. Over time the project developed into a ground-up redesign of a completely new aircraft that combines the knowledge and experience of 1940's & 50's flying boat
