This craft in a stepped planing hull type. It dates from the 1960's and was designed for water races in lakes that were popular in the US at that time. The stepped hull concept is used today in high speed crafts, because it reduces the hull wetted surface at planing speeds, and produces a softer ride since the hull pivots near the step edge.
It is interesting to notice that the high speed crafts of that date were base on automobile concepts (notice how the part of the craft over the water resembles a vintage sport car) and on aerodynamics:
the stepped hulls were based in the flying hydroplanes floating bodies.
The speed depends on the installed motor, normally a car motor of that time, But Are Speeds over 30 knots possible for this craft, in still water.
