What does IALA Region B use for signaling safe water?

In IALA Region B, safe water is indicated by the use of red and white striped buoys. These buoys serve as a clear signal to mariners that they are in a navigable channel or safe water area. The red color is associated with the presence of navigational aids, often indicating the proximity to land or other hazards, while the white stripes provide contrast and improve visibility. The distinctive pattern helps mariners quickly recognize that safe water is ahead, allowing them to navigate confidently.

In contrast, other options like green and white striped buoys or solid red buoys represent different meanings. Green buoys are typically used to mark starboard sides of channels, while solid red buoys denote danger or obstruction. Yellow and black striped buoys could indicate cautionary areas or specific hazards, but they do not signal safe water. Understanding these signals is crucial for safe navigation, and recognizing red and white striped buoys as markers for safe water is an essential aspect of IALA Region B's buoyage system.
