a hydrofoil "planes" on big water skis.


Ummm... Think again:

http://en.wikipedia.org/wiki/Hydrofoil
A hydrofoil is a boat with wing-like foils mounted on struts below
the hull. As the craft increases its speed the hydrofoils develop
enough lift for the boat to become foilborne - i.e. to raise the
hull up and out of the water. This results in a great reduction in
drag and a corresponding increase in speed.

A hydrofoil works much like an aircraft wing, but it works in a fluid
medium with a substantially different viscosity.

Yeah, I should know better.

In my defence I remember some boats from decades ago when I used to
be involved with such things that had big water skis that apparently
never worked out too well or they would still be around.
