Abstract
The present invention is for an elevated tow device made of a superstructure extending skyward from a towboat, where the superstructure raises an attachment point of a tether above 10 feet from the waterline, where the towboat is 25 feet or less in length, and a tether connecting the towboat to a towed subject. The present invention may further include an aerodynamic surface whose angular position is guided by the tether and which acts to stabilize the towboat as the towed subject applies lateral loads. When the towed subject pulls on the side of the towboat, the angle of attack on the aerodynamic surface increases proportionally, and the lateral forces approximately cancel. The towboat proceeds safely with little or no roll perturbation.
