Rules of the Road · Application & Demarcation Lines

The COLREGS Demarcation Lines define the boundary between which two rulesets?

Explanation

The COLREGS Demarcation Lines, published at 33 CFR Part 80, separate the waters where the U.S. Inland Navigation Rules apply (inshore side) from waters where 72 COLREGS apply (seaward side). There are no separate 'Great Lakes Rules' — the Inland Rules cover the Great Lakes.

Authority: 33 CFR Part 80
