Solar and wind-powered sea vehicle

C-Enduro is a long endurance autonomous surface vehicle used to safely and cost effectively collect data at sea. Built to operate in all marine environments, C-Enduro uses energy harvesting technology combined with an efficient self-righting hull.

C-Enduro’s unprecedented payload capacity and power enables the use of a combination of payloads during any one mission. Use of the C-Enduro can dramatically reduce the cost of data collection by removing the need for traditional survey vessels.

Use of mission planning and waypoint setting can often result in a more accurate dataset.
