Canadian Boating Exam Practice Quiz

What sound signal does any vessel run aground make?

1. Two prolonged blasts + one short blast every minute

2. Three bell strokes + five seconds of rapid bell ringing + three bell strokes every minute

3. Continuous ringing

4. One prolonged blast every minute

The correct answer is: Three bell strokes + five seconds of rapid bell ringing + three bell strokes every minute

A vessel running aground is typically in a state of emergency and has a potential for a collision. Therefore, the sound signal required should be distinctive and able to capture the attention of other vessels in the vicinity. Option A, which suggests two prolonged blasts followed by one short blast, is the signal for a vessel being towed, not a vessel running aground. Option C, continuous ringing, is used for vessels restricted in their ability to maneuver, not vessels running aground. Option D, one prolonged blast every minute, is the signal for a vessel anchored, not a vessel running aground. The correct answer, B, is the signal for a vessel in an emergency situation, which would include a vessel running aground.
