USCG Exam PracticeRule 23 — Power-driven Vessel Underway (lights)
On a power-driven vessel of 20 meters or more in length, the sidelights must be placed in which position relative to the forward masthead light?
- A. At least 2 meters lower than the forward masthead light
- ✓ At least 1 meter lower than the forward masthead light, and not forward of itCorrect
- C. At the same height as the forward masthead light but at the sides of the vessel
- D. At least 1 meter lower than the forward masthead light and may be placed forward of it
Why B is correct
33 CFR §84.02(g) requires sidelights to be placed at least 1 meter lower than the forward masthead light, and §84.03(b) prohibits placing them forward of the forward masthead light on a vessel of 20 meters or more. Both conditions must be satisfied simultaneously.
