The correct answer is C) Stowing deck loads forward. Stowing deck loads forward will not reduce the yawing of a tow. Yawing is the side-to-side motion of the tow, and it is primarily affected by the length of the towing hawser, the use of drogues, and the trim of the tow. Stowing deck loads forward does not directly impact the yawing motion. In contrast, options A, B, and D can help reduce yawing by affecting the stability and behavior of the tow.
