USCG Exam PracticeAnchoring — types, scope, holding ground
A group of barges is moored at anchor in a formation where one barge projects outward from the group. In lieu of standard Rule 30 anchor lights, the operator elects to use the alternative lighting arrangement permitted under 33 CFR §83.30(j). How must the projecting barge be lighted?
- A. With a single all-round white light at its highest point
- ✓ On its outboard cornersCorrect
- C. With two all-round white lights in a vertical line on its outboard side
- D. With lights placed only at the bow and stern of the projecting barge
Why B is correct
33 CFR §83.30(j)(i) specifies that any barge projecting from a group formation shall be lighted on its outboard corners when using the alternative arrangement permitted under §83.30(j). This ensures the extremities of the projecting barge are marked for passing vessels. The other options describe arrangements not specified in this subsection.
