Question

question 7 of 60
when encountering other vessels in darkness or reduced visibility, what do visible white and green lights indicate?
a you are approaching the stem of another vessel
b you are approaching the port side of another vessel
c you are approaching a powerboat head - on
d you are approaching the starboard side of another vessel

Explanation:

In maritime navigation, different colored lights on vessels have specific meanings. A white light is typically the stern light (at the back of a vessel). The green light is the starboard (right - hand side) sidelight. When you see a white and green light, it means you are approaching the starboard side of another vessel.

• Option A: If approaching the stern, you would only see the white stern light, not the green sidelight.
• Option B: The port side has a red sidelight, not green.
• Option C: A head - on powerboat would show both red and green sidelights (along with a white light in some cases, but not just white and green as described here).

Answer:

D. You are approaching the starboard side of another vessel
