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.

The viscosity is different, but an airplane wing also works in a fluid.
Maybe you meant liquid?

I meant what I said, and I fail to infer the point you are attempting
to make. I chose the word 'fluid' specifically because it is the
correct term for both media.
