The 12th annual International Submarine Races (ISR) took place the last week of June at the Naval Surface Warfare Center (NSWC) Carderock Division. Students were given two years to build a one- or two-person human-powered submarine, which they would race along a 100 meter course in a model basin at the NSWC. Because the subs aren’t waterproof, the teams compete while wearing full scuba gear.
Contestants must follow a 44-page manual, and subs generally cannot be reused from prior years. Because the race takes place every two years teams have some time to plan their vessels.
