90% to pass

BOTH INTERNATIONAL & INLAND Which of the following shapes shall a powerdriven vessel when towing (length of tow exceeds 200 meters) exhibit during daylight?

A two cones, apexes together
B a black ball
C one cone, apex upward
D a diamond shape
AI Explanation

The correct answer is D) a diamond shape. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a power-driven vessel towing another vessel where the length of the tow exceeds 200 meters must exhibit a diamond shape where it can best be seen during daylight hours. This is specified in Rule 24(c) of the COLREGS. The other options are incorrect because they do not match the specific requirement for a diamond shape in this situation. Options A, B, and C describe different shapes that are used for other types of vessels or situations, but not for a power-driven vessel towing a long tow during daylight.
