Rule 10 – Traffic separation schemes

Section 1 — Conduct of Vessels in any Condition of VisibilityRule 10: Traffic separation schemesa. This Rule applies to traffic separation schemes adopted by the Organization and does not relieve any vessel of her obligation under any other Rule.Meaning: The objective of this rule of the COLREGS is that although IMO may enforce traffic separation schemes, but the instructions in this rule shall not go against the rules as stated elsewhere in the COLREGS.

What is "narrow" depends on the type of vessel and the circumstances. A "channel" is a natural or dredged lane restricted on either side by shallow water; it is … [Read more...]
