On 27 October 1991, Mark Drela pedalled the human-powered hydrofoil, Decavitator, to a world-record speed of 18.5 knots, 9.53 m/s, 34,3 km/h over a 100 meter race course on the Charles River in Boston, Massachusetts.

In the spring of 1993 the Decavitator team was awarded the DuPont prize for the fastest human-powered water craft. This prize was to be awarded to the first team to break 20 knots over a 100 meter course, or to the team with the fastest speed on record as of 31 December 1992.
