An expanded field of contestants and steady advances in subsea technology were highlights of the 12th International Submarine Races (ISR), with the consistently-winning Canadian team from the University of Quebec's Ecole de Technologie Superi-eur continuing to demonstrate engineering design leadership. The races were held June 24 to .28 at the U. S. Naval Surface Warfare Center's Car-derock Division David Taylor Model Basin in Bethesda, Maryland, with 19 teams submitting 21 submarines from throughout the world, competing for prizes, academic recognition and personal achievement. The human-powered submarine teams came from the U.S., Canada, Mexico, the U.K., Germany, the Netherlands and Oman. The biennial event, launched initially in 1989, challenges the engineering creativity of college, high-school and independent students, inventors and entrepreneurs. The race awards are categorized by one- or two- person subs, propeller or nonpropeller driven, and college/ university, high-school or independent teams.
