Question
A freshwater boat of mass 400 kg is supported by a rectangular
hydrofoil of aspect ratio 8, 2 percent camber, and
12 percent thickness. If the boat travels at 7 m/s and α = 2.5°,
estimate (a) the chord length, (b) the power required if
CD∞ = 0.01, and (c) the top speed if the boat is refitted with
an engine that delivers 20 hp to the water.
