Seaplanes have a complex interaction of aerodynamic, hydrostatic and hydrodynamic forces during acceleration to take off speed.
A number of floatplanes are power limited and unable to transition from a low speed displacement taxi to high speed planing at high weights and/or high density altitudes.
The location of the center of gravity, the position of the elevators and flaps can determine whether the aircraft will accelerate through this high drag transition with the same load and wind. Different wind strengths and relative directions require different techniques.
These interactions could make for an intersting thesis.
