Multiple Choice

In a sailing crossing on your starboard bow with another sailing vessel, what is the initial signal if you doubt they will take action?

In this situation the most effective way to prevent a collision is to clearly communicate your intended maneuver. Day signals using flag letters provide a visible, unambiguous way to tell the other vessel what you plan to do, even if you doubt they’ll take action. Flag signals are designed for exactly this purpose in daylight and are more reliable than relying on sound signals alone or making an immediate course change without clear communication. The other options involve whistle signals or an abrupt maneuver, which can be misinterpreted or too late, whereas hoisting the appropriate flag communicates your intent directly.
