INTERNATIONAL ONLY A partially submerged object towed by a vessel, during the day, must display which of the following shapes?

A a black ball only when the length of the tow exceeds 200 meters in length
B a black ball
C a diamond shape when the length of the tow exceeds 200 meters in length
D a diamond shape when the length of the tow is 200 meters or less
AI Explanation

The correct answer is D) a diamond shape when the length of the tow is 200 meters or less. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a partially submerged object towed by a vessel during the day must display a diamond shape when the length of the tow is 200 meters or less. This is specified in Rule 24(e) of the COLREGS. The other options are incorrect because a black ball is only required when the length of the tow exceeds 200 meters, and a diamond shape is not required when the tow length is greater than 200 meters.
