Abstract
Techniques are provided for an unmanned surface vehicle including a vehicle body and a rigid square-rig wing coupled with the primary vehicle body. The rigid square-rig wing includes a first surface configured to interact with wind to generate a force that propels the primary vehicle body in a direction of travel that is primarily composed of drag, and a second surface configured to interact with the wind to generate a force that propels the primary vehicle body in a direction of travel that is primarily composed of lift. The unmanned surface vehicle further includes a rudder and a control system comprising a controller, the control system configured to determine a rudder position and generate a signal to position the rudder to the rudder position.
