What color is the starboard sidelight?

• A. Green
• B. Red
• C. Blue
• D. White

Answer: (A)

Boats use colored navigation lights so others can quickly tell which direction you’re traveling at night. The sidelight on the right side of the boat—the starboard sidelight—is green, while the left side—the port sidelight—is red. A white light is used at the stern (rear) and/or as an all-around light in certain conditions. This color coding helps prevent collisions by letting other mariners identify which side you’re on at a glance. So green is the correct color for the starboard sidelight. The other colors listed don’t apply to the starboard side.
