90% to pass

BOTH INTERNATIONAL & INLAND Vessels of less than what length may not impede the passage of other vessels which can safely navigate only within a narrow channel or fairway?

A 10 meters
B 20 meters
C 30 meters
D 40 meters
AI Explanation

The correct answer is B) 20 meters. According to the International Regulations for Preventing Collisions at Sea (COLREGS), which apply to both international and inland vessels, vessels of less than 20 meters in length may not impede the passage of other vessels which can safely navigate only within a narrow channel or fairway. This is specified in Rule 9(b) of the COLREGS. The other options are incorrect because the length limit for this rule is 20 meters, not 10, 30, or 40 meters.
