Question 905Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND A vessel nearing a bend or an area of a channel or fairway where other vessels may be obscured by an intervening obstruction shall sound which signal?
AI Explanation
The correct answer is A) One prolonged blast.
According to the International and Inland Navigation Rules (72 COLREGS), a vessel nearing a bend or an area of a channel or fairway where other vessels may be obscured by an intervening obstruction shall sound one prolonged blast. This signals that the vessel is approaching a blind bend or area where other vessels may not be visible, alerting other vessels in the vicinity to be cautious.
The other options are incorrect because: B) One long blast is not the correct signal, C) The danger signal (five or more short blasts) is used to indicate danger or the need for immediate action, and D) Two short blasts is the signal used to indicate a vessel is changing direction to starboard.
