When your on the water and you do not understand what another boater intends to do what sound signal should you make?

When you're on the water and unsure of another boater's intentions, you should make a one-long-blast sound signal using your horn or whistle. This signal indicates that you are uncertain about their actions and prompts them to communicate their intentions more clearly. It's essential to remain vigilant and prepared to maneuver as needed for safety. Always follow the navigational rules and guidelines for sound signals in your area.
