Learn More from Saildrone

Saildrone USVs are designed to perform in the harshest ocean conditions on the planet, including those that crewed ships often avoid. On its return trip, SD 1021 took the direct northern route, sailing predominantly upwind and against the current, completing the 3,402-nautical mile (6,301.59-kilometer) passage in just 68 days.

The vehicles are powered exclusively by the wind for propulsion and use solar energy to run onboard computers and navigational instruments. They are equipped with a suite of science-grade sensors to collect oceanographic and meteorological data above and below the sea surface including wind speed and direction, air and sea surface temperature, atmospheric pressure, photosynthetically available radiation, wave height and period, dissolved oxygen, salinity, and acidity levels.
