When is it typically most important to communicate intentions with other boats?

Communicating intentions with other boats is particularly crucial at night or in low visibility conditions. In these scenarios, visibility is significantly impaired, making it difficult for boaters to see each other and anticipate maneuvers. Effective communication through sound signals, navigation lights, or other means becomes essential for ensuring safety on the water. At night or during foggy weather, boaters rely heavily on these signals to avoid collisions, as they may not see other vessels until they are very close. Thus, being clear about your intentions when visibility is limited helps maintain a safer boating environment for everyone involved.
