Abstract: A directional cannonball weight having a body made of solid, non-buoyant mass of substantially homogeneous material with a skag defining a vertical plane and serving as a rudder, extending outwardly from the body and defining an oblique angle with the direction of travel of the weight while the weight is under tow. The body and skag may be constructed as a single monolithic structure, or with the body having a slot formed in the body, a pin for pivotally fixing the skag to the body within the slot on the body so the skag protrudes from the slot of the body and may extend in varying angular orientations with respect to the body as the skag is pivoted around the pivot pin and a locking bolt for fixing the skag at a desired position.
