A tow astern is veering from side to side on its towline. The best way of controlling the action is to __________.

Correct Answer: Option B — trim the tow by the stern

Trimming a tow by the stern increases the draft aft, which improves the directional stability of the towed vessel. This deeper immersion of the stern creates a greater resistance to lateral movement, effectively dampening the yawing motion and keeping the tow tracking straight behind the towing vessel.
