Proper Navigation When Approaching a Green Marker Buoy

When encountering a green marker buoy while heading upstream (returning from sea), how should you proceed?

a) Keep the marker on your starboard (right) side
b) Keep the marker on your port (left) side
c) Pass on either side of the marker
d) Turn around--you may not proceed any further

Answer:

When encountering a green marker buoy while heading upstream (returning from sea), you should keep the marker on your starboard (right) side.

Explanation:

When encountering a green marker buoy while heading in the upstream direction (returning from sea), you should keep the marker on your starboard (right) side. This rule is part of the 'Red, Right, Returning' system used by mariners to navigate waters. These markers indicate the edge of the channel or a danger spot and help direct boats safely through waters. While the green marker should be on your starboard side when returning upstream, the red should be on your port (left).

Aids to Navigation:

These markers are called Aids to Navigation (AtoN) and are critical for safety at sea. This system helps vessels to orient themselves in relation to land and potential hazards, especially in poor visibility conditions. Therefore, knowing how to interpret these buoys and markers is a crucial skill for all mariners.
