The sweeping removes debris, and warms the surface, creating a hydroplane-like effect.
It could also be transformed into a hydroplane.
The brakes can be used to help steer in fresh snow, or other conditions where the front wheel will hydroplane instead of steering.
The modern turbine-powered unlimited hydroplane is derived from the 3-point prop-riding hydroplanes of the 1950s.
The other theory is that the flooding of the hangar was due to failure of the stern hydroplanes.
Early hydroplanes had mostly straight lines and flat surfaces aside from the uniformly curved bow and sponsons.
In practice this proved totally ineffective since the weights could not be moved quickly enough and hydroplanes and fins were subsequently fitted.
In the late 1950s and early 1960s, he competed in unlimited hydroplane racing.
