What colors do preferred channel marks feature?

Preferred channel marks are specifically designed to indicate the preferred direction for vessels navigating through channels. These marks aid in directing boats safely and efficiently by clearly signaling the preferred side of the channel.

The correct colors for preferred channel marks are red and green. Typically, red marks are used on the right side of the channel when entering from the sea, while green marks are on the left. Together, these colors help boaters recognize the safest navigation route to follow. The distinction between red and green marks is vital for mariners, as it correlates to the "I can" mnemonic used in navigation, which indicates that vessels should keep the red marks on their right side when heading upstream.

Understanding the significance of these color codes fosters safer navigation practices and reduces the risk of accidents in busy waterways.
