How is a starboard lateral buoy typically marked during the day?

A starboard lateral buoy is marked with a green color during the day. This system is part of the IALA (International Association of Lighthouse Authorities) Maritime Buoyage System, which uses color coding to indicate the safe channel for vessels. For a starboard lateral buoy, the green color serves to inform mariners that they should keep this buoy on their starboard (right) side when navigating into port or upstream.

The choice of green for starboard buoys helps create a clear and consistent visual cue for navigators, enhancing safety and promoting accurate navigation. In addition to the color, starboard buoys are also typically marked with a conical shape or a topmark, further distinguishing them from other types of buoys. This uniformity in marking is essential for effective maritime navigation, ensuring that mariners can quickly identify and understand the navigational aids in their vicinity.
