BOTH INTERNATIONAL & INLAND What shape must be shown on a partly submerged vessel which is being towed?

Correct Answer: Option A — A diamond

Rule 24(g) mandates that a partly submerged vessel or object being towed must exhibit a diamond shape where it can best be seen. This shape provides a clear visual signal to other mariners that the object is under tow, regardless of its size or the length of the towline.
