BOTH INTERNATIONAL & INLAND What shape should a vessel being towed exhibit if the tow EXCEEDS 200 meters?

A Two balls
B One diamond
C Two diamonds
D One ball
AI Explanation

The correct answer is B) One diamond. According to the International and Inland Navigation Rules, when a vessel is being towed and the length of the tow exceeds 200 meters, the towing vessel must exhibit one diamond shape where it can best be seen. This diamond shape is a navigational signal that indicates the length of the tow, which is important for other vessels to be aware of in order to safely navigate around the tow. The other answer choices are incorrect because they do not match the specific requirement for a single diamond shape when the tow exceeds 200 meters. Two balls, two diamonds, or one ball would not be the proper signal in this situation.
