What is the procedure for on-water communications and call signs?

• A. Use the base-issued radio channel, monitor appropriate channels, identify your vessel and trip plan to base control or other vessels as required.
• B. Use private mobile phone only
• C. Use hand signals instead of radios
• D. Do not identify your vessel or trip plan

Answer: (A)

On-water communications rely on clear radio procedures and call signs to keep everyone safe and coordinated. The best practice is to use the base-issued radio channel, monitor the appropriate channels so you can hear traffic and respond when needed, and clearly identify your vessel and trip plan to base control or other vessels as required. This approach provides accountability, situational awareness, and a traceable record of who is communicating, where you are, and what you intend to do, which is essential for coordination and emergency response. Using a private mobile phone bypasses the shared, monitored channel system and can’t be reliably tracked or integrated with base operations. Hand signals alone can’t convey everything needed for safe navigation and coordination, and failing to identify your vessel or trip plan undermines safety and accountability.
