In a narrow channel, where should a vessel position itself relative to the outer limit on its starboard side?

• A. Stay in the center of the channel.
• B. Keep as near as practicable to the outer limit of the channel on the starboard side.
• C. Veer to port to pass close to the other vessel.
• D. Stop and anchor if traffic is heavy.

Answer: (B)

In a narrow channel, traffic should keep to the starboard side so there’s maximum safe space for opposing or meeting vessels and for maneuvering. Hugging the outer limit on your starboard side means you position near the right-hand edge of the channel, as close as safety allows. This keeps the center and the left side clearer, reducing the chance of grounding or a close-quarters situation with other vessels. Veering to the port to pass close to another vessel or stopping in heavy traffic would increase risk and isn’t how traffic in a confined channel is managed. So the best approach is to stay near the outer limit on the starboard side.
