Explain how float and hull construction can affect seaplane performance.
Explain how float and hull construction can affect seaplane performance.
Bottom line
Floats and hulls are carefully designed to optimize both hydrodynamic and aerodynamic performance. Construction and materials of floats and hulls have changed over time, always favoring strength and light weight. As seaplane weight increases, the floats sink deeper into the water, creating more drag during initial acceleration.
