What is the purpose of using different colored marks and buoys?

The use of different colored marks and buoys serves the vital function of providing crucial navigational information to vessels. Each color and marking pattern conveys specific meanings that help mariners safely navigate through waterways. For instance, red markers typically indicate the right side of a channel when approaching from seaward, while green markers denote the left side. This system allows for effective communication of navigational routes, hazards, and other important information related to the safe movement of vessels.

By constructing a coherent system of colors and symbols, mariners can quickly and accurately interpret their surroundings, making decisions that enhance safety and efficiency during travel. This ability to decipher navigational aids is critical for avoiding collisions, grounding, and other maritime accidents. Thus, the strategy of employing distinct colors and signs is indispensable in maritime navigation.
