Question 3

You are boating on a river heading upstream. Which side should you keep the red buoys on?

Starboard (right)

On rivers, 'returning from sea' means heading upstream, so red buoys should be kept on your starboard (right) side.

Question 4

What is the purpose of a range light system in a waterway?

Accepted Answer

To indicate a safe course by aligning two lights

Range lights consist of two lights at different heights; when aligned (one above the other), they indicate the vessel is on the correct course.

Red-and-white vertically striped buoys (safe water marks) indicate safe, open water on all sides and often mark mid-channels or fairway entrances.
