Question 3926Deck General70% to pass
You intend to overtake a vessel in a narrow channel. As you approach the other vessel's stern _______________.
AI Explanation
The correct answer is A) the vessels will drift together.
When overtaking a vessel in a narrow channel, the overtaking vessel should pass the other vessel on the side that gives the best and safest clearance. As the overtaking vessel approaches the stern of the other vessel, the interaction of the water flows around the two vessels can cause them to drift together, rather than drift apart. This is due to the "bank cushion" effect, where the confined waters of the narrow channel can push the vessels towards each other. Maintaining a safe distance and reducing speed is crucial to avoid collision in this situation.
The other options are incorrect because: B) you will not gain speed when overtaking in a narrow channel, as you need to reduce speed to safely pass; C) the vessels will not drift apart, due to the bank cushion effect; and D) the vessels should not gain speed, as that would increase the risk of collision.
