In United States waters, a buoy having red and white vertical stripes has a light characteristic of ______.

The light characteristic of a buoy with red and white vertical stripes in United States waters is Morse (A). This specific color pattern and light characteristic are associated with safe water markers, which guide mariners to navigable channels. The Morse (A) signal consists of a short flash followed by a long flash, which is distinct and easily recognizable.

The use of red and white vertical stripes serves to ensure that the buoy stands out visually in the environment, allowing for quick identification and enhancing navigational safety. The Morse signal reinforces the visual characteristics of the buoy, aiding in nighttime or low visibility navigation. This combination of color and light helps convey important navigational information to mariners, alerting them to the safe water surrounding the buoy.

Recognizing these aids to navigation and their specific characteristics is crucial for safe maritime navigation, as they assist in avoiding hazards and maintaining proper course.
