USCG Exam PracticeRule 25 — Sailing and Rowing Vessels (lights)
A sailing vessel underway is required by the Inland Navigation Rules to exhibit which lights as its basic requirement?
- A. Masthead light, sidelights, and sternlight
- ✓ Sidelights and sternlightCorrect
- C. All-round white light and sidelights
- D. Sidelights, sternlight, and an all-round red over green at the masthead
Why B is correct
33 CFR §83.25(a) requires a sailing vessel underway to exhibit sidelights and a sternlight. A masthead light is not required for a sailing vessel; that is a power-driven vessel requirement under §83.23(a). The red-over-green all-round lights are an optional addition under §83.25(c), not a basic requirement.
