The calculation of wing float displacement in single-float seaplanes

Edward P. Warner
Mar 1925

The lateral stability of all single-float seaplanes and flying boats except those of the Dornier type with lateral extensions on the hull itself must be assured by the use of auxiliary floats at the wing tips, these floats being mounted high enough so that they make contact with the water only when the seaplane is heeled over to one side or the other and so that only one of the wing floats can be in contact with the water at a given time.
