Rules of the Road · Fishing Vessels

You observe a vessel at night showing an all-round red light above an all-round white light, sidelights, and a sternlight. What type of vessel is this?

Explanation

Red over white is the signature of a fishing vessel not engaged in trawling. The presence of sidelights and a sternlight confirms she is making way through the water. A NUC vessel would show red over red, not red over white.

Authority: 72 COLREGS Rule 26(c)
