Claims12
A float construction of the type primarily intended for use in supporting a seaplane, said float comprising:
- a main body defining a major longitudinal dimension;
- a step extending across the bottom of said main body in substantially transverse relation to said major longitudinal dimension;
- a bow extending forwardly of said step, said bottom of said main body curving upwardly as it extends forwardly of said step along said bow, said bow defining a simple concave cross-section with regard to said major longitudinal dimension extending inwardly from the outboard edges of said bow with the apex of said cross-section defining the longitudinal midpoint of said bow;
- and a tail extending rearwardly of said step, said tail comprising a first tail section defining a simple concave cross-section with regard to said major longitudinal dimension and a second tail section defining a simple convex cross-section with regard to said major longitudinal dimension, wherein said first and said second tail sections each define congruent cross-sectional planes at their intersection, said first tail section extending rearwardly from said step and said second tail section extending rearwardly from said first tail section.
