Question 154 Rules of the Road

The correct answer is A) 20 meters. According to the International Regulations for Preventing Collisions at Sea (COLREGS), in narrow channels, vessels of less than 20 meters in length shall not impede the safe passage of vessels which can navigate only inside that channel. This regulation applies to both international and inland waters. Vessels larger than 20 meters must give way to those that can only safely navigate within the narrow channel. The other options are incorrect because 50 meters (B), 65 meters (C), and 100 meters (D) are all larger than the 20-meter limit specified in the COLREGS for vessels that must not impede the safe passage of other vessels in narrow channels.
