Rule 28 - Vessels Constrained by their Draught

Back to COLREGs in Depth

Overview

Rule 28 defines the lights and shapes applicable to vessels constrained by their draught (CBD).

The rule specifically mentions the lights and shapes required for power-driven vessels, and should therefore be read in conjunction with Rule 23.

Rule 28 - Vessels Constrained by their Draught

A vessel constrained by her draught may, in addition to the lights prescribed for power-driven vessels in Rule 23, exhibit where they can best be seen three all-round red lights in a vertical line, or a cylinder.
