Thank you for your answers,
john tullamarine and
MechEngr! I found the site hyperlinked below to be interesting. It includes some brief but breath-taking video of hydrofoil vessels under full sail. Interesting that the foil itself is a blade two meters in l.o.a. and a width of 0.7 meters. I continue to search for a cross-sectional representation. Astounding to me that these beasts can make in excess of 60 knots!
