What famous inventor co-designed a hydrofoil boat that held the world water-speed record for over 40 years?

Although there was no telephone aboard, I believe it was Alexander Graham Bell.

How do you always know these answers, Racer?

My source is SeattlePI.com:

"A hydrofoil co-designed by telephone inventor Alexander Graham Bell set the world water-speed record of 70-plus miles per hour in 1919, a record that stood until 1963."

Thanks for your answer, all-knowing Racer!

This was the same Alexander Graham Bell who, upon inventing the telephone, said, "Come here, Dorian, I want you"!

You rang?
