Question

The light rhythm of Morse (A) is shown on what type of buoy(s).

a. Starboard or port-side buoys
b. Preferred-channel buoys
c. Special marks
d. Safe water buoys

Answer 1

The light rhythm of Morse (A) is used on special mark buoys, which serve specific purposes for mariners such as indicating special areas rather than channel edges.

Step-by-step explanation:

The light rhythm of Morse (A) is shown on special mark buoys. These buoys have specific purposes, such as indicating the location of fishing nets, pipelines, or marine reserves, rather than showing the edges of safe water channels like starboard or port-side buoys, preferred channel buoys, or safe water buoys. Morse (A) is a light rhythm consisting of one short and one long flash, used to help mariners identify the buoys from a distance, especially at night or in poor visibility conditions.

Answer 2

Safe water buoys exhibit the Morse (A) rhythm, indicating safe water for mariners to approach or navigate around.

Step-by-step explanation:

The correct answer to which type of buoy exhibits the light rhythm of Morse (A) is safe water buoys. Safe water buoys are used to indicate there is safe water in all directions around the mark. They are often found at the ends of channels or as fairway buoys and exhibit the Morse (A) rhythm to signify "A"pproach or safe water. This indicates to mariners that they are entering a channel or at a point that is safe to pass. In contrast, starboard or port-side buoys are used for indicating the sides of channels, preferred-channel buoys indicate a bifurcation or junction in a channel, and special marks are used for administrative or informational marks not primarily intended for navigation.
