What is it about?
When seaplanes take off from or alight on water, pilots need to be careful so that the aircraft does not go into a dangerous coupled oscillation mode between planing and heaving called porpoising. This paper proposes a method to avoid this oscillation by design of the hull and the support system between the aircraft and the floats.

Why is it important?
1. Porpoising is a poorly understood phenomenon, understanding how to avoid it may contribute to the safety of seaplane operations and increase availability of seaplanes. 2. It shows a way to mitigate the risk of porpoising by design. The proposed method has a potential to enable more detailed trade off analysis in stability of seaplanes at conceptual study stage i.e. let you perform parametric studies. 3. It shows a new way to mitigate porpoising using "flexible support".
