Wave Glider began as a project listening to humpback whales in real-time off the coast of Hawaii.
A Wave Glider set the Guinness Record for longest journey by an autonomous, unmanned surface vehicle in 2013 by traveling 9,380 nautical miles (17,372 km) on a pre-programmed path from San Francisco Bay to Lady Musgrave Island near Bundaberg, Australia.
Wave Gliders can withstand high seas, and have even navigated through 17 hurricanes.
- Capable of operating autonomously for months at a time without fuel. System composed of three parts: the float at the surface, 8-meter umbilical line, and a sub under water. Can be equipped with a range of sensors to perform missions for marine science, commercial, and defense applications.

- Camera, CTD (conductivity, temperature, and depth) sensor, wave sensor, weather station, fluorometer, hydrophone, acoustic Doppler current profiler sonar, marine acoustics sensors.
- One stepper motor (to control rudder position).
- Mechanical conversion of wave energy into forward propulsion. On-board electronics and sensors powered via solar panels and batteries.
- Central control unit, plus other processors and controllers based on customer requirements
- On-board: custom control software. Shore-side software: Web-based system.
- DEGREES OF FREEDOM (DOF)
- Float made of e-glass pre-preg composite with foam cores. Glider consists of stainless steel frame and fiberglass wings, with a titanium "thrudder."
