Navigation Rules (COLREGS)
The Navigation Rules establish actions to be taken by vessels to avoid
collision. The Rules are divided into two parts, INLAND and INTERNATIONAL.
U.S. Inland Rules apply to vessels operating inside the line of
demarcation while International Rules apply outside the lines. Demarcation lines are
printed on most navigational charts and are published in the Navigation
Rules. You can also find info about the Demarcation Lines
