USCG Exam PracticeRule 28 — Constrained by Draft (lights)
At night, a vessel not under command that is making way through the water is required to exhibit which lights?
- ✓ Two all-round red lights in a vertical line, sidelights, and a sternlightCorrect
- B. Three all-round lights (red-white-red) in a vertical line, sidelights, and a sternlight
- C. Two all-round red lights in a vertical line only — no sidelights or sternlight
- D. Two all-round red lights in a vertical line and a masthead light
Why A is correct
33 CFR §83.27(a)(i) and (iii) require a vessel not under command to show two all-round red lights in a vertical line, and when making way, sidelights and a sternlight in addition. No masthead light is prescribed for a NUC vessel. The red-white-red pattern belongs to a RAM vessel under §83.27(b).
