USCG Exam Practice · Rule 28 — Constrained by Draft (lights)
A vessel not under command that is making way through the water is required to exhibit which combination of lights?
- ATwo all-round red lights in a vertical line, sidelights, and a sternlight✓ correct
- BThree all-round lights — red, white, red — in a vertical line, sidelights, and a sternlight
- CTwo all-round red lights in a vertical line only; sidelights and sternlight are not required
- DTwo all-round red lights in a vertical line and a masthead light
Why A is correct
33 CFR §83.27(a) prescribes two all-round red lights in a vertical line for a vessel not under command. Paragraph (a)(iii) adds that when making way through the water, sidelights and a sternlight shall also be exhibited. The red-white-red combination in a vertical line is the signal for a vessel restricted in her ability to maneuver under §83.27(b).
