Abstract
Apparatus and methods are disclosed relating to a body towable behind a vessel in a body of water, an arm rotatably coupled to the body, and one or more foils disposed on the arm. The arm, when deployed, is configured to be free to rotate as the apparatus is towed through the body of water. The one or more foils are configured to generate lift as the apparatus is towed. Due to the free rotation of the arm, the foils impart tension force to the body and not torque forces.
