The Wüst Seahawk is a German
amateur-built flying boat
A flying boat is a type of seaplane with a hull, allowing it to land on water. It differs from a floatplane in having a fuselage that is purpose-designed for flotation, while floatplanes rely on fuselage-mounted floats for buoyancy.

Design and development
The Seahawk was originally the Mark Flugzeugbau Shark, but that company went out of business and Wüst continued development of the design.
The Seahawk features a cantilever
shoulder-wing
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple wings.
A monoplane has inherently the highest efficiency and lowest drag of any wing config ...

wing tip
A wing tip (or wingtip) is the part of the wing that is most distant from the fuselage of a fixed-wing aircraft.
Because the wing tip shape influences the size and drag of the wingtip vortices, tip design has produced a diversity of sha ...
