90% to pass

INTERNATIONAL ONLY Which vessel sounds the same fog signal as a vessel not under command?

A A towed vessel
B A sail vessel
C A WIG craft underway
D A vessel aground
AI Explanation

The correct answer is B) A sail vessel. Under the International Regulations for Preventing Collisions at Sea (COLREGS), a sail vessel not under power is required to sound the same fog signal as a vessel not under command, which is a rapid and regular ringing of a bell. This is outlined in Rule 35(c) of the COLREGS. The other options are incorrect because: A) A towed vessel would sound a different fog signal, C) A WIG (wing-in-ground) craft underway would sound a different signal, and D) A vessel aground would sound a different signal as well.
