If you're rushing off to beltsand some wooden foils for a crazy hydrofoil right now, be aware
the foil sections depicted in these diagrams do not resemble the sections of the actual device.

That said, here are some foil section candidates:
The Eppler E817 and "Ogive" sections are popular with Hydrofoil Society Members.
NACA 63412 and H105 are used by the Moth hydrofoil dinghy and others made by the same folks.
