Rule 9
Narrow channels
Keep as near the starboard outer limit of the channel as is safe — small craft, sailboats, and fishing vessels must not impede.
In plain language
In a narrow channel, drive on the right: keep as close to the channel edge on your starboard side as is safe and practicable. Vessels under 20 m, sailing vessels, and vessels crossing the channel must not impede a vessel that can only navigate safely inside it; a vessel engaged in fishing must not impede the passage of any other vessel navigating within the channel at all. Approaching a blind bend, sound the bend signal and proceed with particular alertness — and avoid anchoring in a channel at all.
This rule differs under the US Inland Rules. Change the rule set in language and regional settings to see the difference.
