USCG Exam PracticeRule 25 — Sailing and Rowing Vessels (lights)
A sailing vessel of 15 meters in length is exhibiting the combined lantern permitted by Rule 25(b) at or near the top of the mast. May she simultaneously exhibit the two all-round lights (red over green) permitted by Rule 25(c)?
- A. Yes, provided the all-round lights are at least 1 meter above the combined lantern
- B. Yes, the two arrangements are always compatible
- ✓ No, the two all-round lights shall not be exhibited in conjunction with the combined lanternCorrect
- D. No, because a 15-meter sailing vessel is not permitted to use a combined lantern
Why C is correct
33 CFR §83.25(c) explicitly states that the optional red-over-green all-round lights shall not be exhibited in conjunction with the combined lantern permitted by paragraph (b). A vessel of less than 20 meters may use the combined lantern under §83.25(b), but not simultaneously with the §83.25(c) lights.
