Question 691 Rules of the Road

The correct answer is A) A pilot vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a pilot vessel, when underway and not making way, is required to exhibit sidelights. This is stated in Rule 29(b) of the COLREGS, which specifies the lights to be exhibited by vessels engaged in pilotage duty. The other options are incorrect because: B) A vessel engaged in dredging is not specifically required to exhibit sidelights when underway and not making way; C) A vessel trawling is required to exhibit different lights as per Rule 26; and D) A vessel not under command is required to exhibit different lights as per Rule 27.
