Low Drag Technology Applied to Human Powered Vehicles

The First International Human Powered Submersible race, scheduled for June 23-25, 1989, has provided the opportunity to explore low drag vehicle technology with the added constraint of low cost. The competition brings together up to nineteen different concepts for minimal drag submersibles capable of transporting two SCUBA divers by human power alone over a distance of 1000 meters. While drag reduction techniques have been a Holy Grail for naval architects, this is perhaps the first time a concerted effort has been mounted to produce a low drag sub at a moderate level of cost. In fact, cost effectiveness, speed, and innovation are the three judging criteria used to evaluate the overall winner.
