Course Outline

When commercial vessels are towing or pushing a barge, they display one or more yellow lights in place of a sternlight. There may be an unlit space of several hundred yards between the lights displayed on the bow and stern of the composite formed by the commercial vessel and its barge(s). Learn to recognize commercial vessel lights if boating on rivers, harbors, or coastal waters.
