His imaginative dedication changed
sailing forever

Arvel had a plentiful professional career that included involvement in aerodynamics research with the best aerodynamics groups in the whole world, like NASA, Lockheed, Douglas, McDonnell Douglas and Boeing. His name rose to sailing-fame on the early 1970s when he published many sail-aerodynamic articles aimed at the average sailor, and he changed sailing for ever. His approach to sailing from a scientific point of view started a process whose outcomes we see now everywhere, both in the aero- and hydrodynamic fields of sailing. The world of sailing owes much to Mr. Gentry.
