Abstract
A stabilizing device for an underwater towed body includes a vertically mble keel inside the towed body using an electric motor. Major part of the imbalanced torque of the tow cable provides rotation of the towed body. A final correction of the rolling motion of the towed body is accomplished by moving a keel weight housed inside the towed body. The extension of the keel weight is controlled by the power applied to the electric motor which is controlled from the surface ship. A sensor sends rolling motion information to the surface ship via the tow cable.
