Design is minds-on

Designing a solar-powered boat requires teams to learn about energy-systems technology, hull design, and materials science. The goal is to engineer a one-passenger solar-powered craft that is innovative, fast, and agile.

Designers research hull forms.

Racing is all hands and minds on deck

Teams compete in four events — Maneuverability, Speed, Endurance, and Capacity to run on direct solar power without battery support. Crews must demonstrate their knowledge of seamanship and marine safety.

Spectators cheer racers on to the finish.

The ride is electric

Most boats in the regatta use a simple solar electric system. Components include an 85-watt solar electric panel that transforms solar radiation into electrical energy, which charges a 12-volt battery that drives a 12-volt motor that turns the propeller. That's sailing on sun power!

Building is hands-on

In building a solar-powered boat, teams learn how to use tools and materials with skill and imagination. Judges rate teams on their level of craftsmanship, creative painting, and project documentation.

A special paint job adds the final touch.

Winners gain glory, skill and confidence

Trophies are awarded to the best boat and runner-up in each class. The best in each class also receives a cash prize. Ask past solar boat teams what they remember most, and they'll tell you about the thrill of the race, having fun with friends, and creating a real solar-powered boat.
