Why Communication Matters

Most boating incidents are not caused by equipment failure — they are caused by misunderstanding, delayed calls, or unclear radio traffic. Good communication keeps waterways organized and allows emergency responders to prioritize correctly.

Core Communication Principles

1. Think Before You Transmit

• Listen first to confirm the channel is clear.
• Know who you are calling and why.
• Keep messages short and direct.

2. Use Plain, Structured Language

• Speak slowly and clearly.
• Avoid slang or unnecessary chatter.
• State vessel name first.
• Repeat critical information.

3. Keep Channel 16 Clear

• Channel 16 is for distress, safety, and hailing only.
• Move conversations to a working channel once contact is made.
• Avoid long conversations on the emergency channel.

Standard Call Format

Use this simple structure:

• Name of vessel being called (3 times)
• Your vessel name (once)
• Your position
• Your request or message
• Proposed working channel

Example:

“Harbor Master, Harbor Master, Harbor Master — this is vessel Bluefin. Request docking instructions. Switching to Channel 68.”

Good Radio Technique

• Hold microphone 1–2 inches from mouth.
• Press button → pause → then speak.
• Release button fully when finished.
• Avoid talking while turning or moving away.
• Reduce background engine noise if possible.

Situational Awareness

• Monitor weather broadcasts regularly.
• Listen for Sécurité or navigation warnings.
• Keep volume high enough to hear distress calls.
• Maintain watch when underway.

Common Communication Mistakes

• Talking too fast under stress.
• Forgetting to state position.
• Using Channel 16 for casual talk.
• Holding transmit button too late.
• Failing to acknowledge incoming calls.

Digital Selective Calling (DSC)

Modern VHF radios include DSC distress alerting. When properly configured with an MMSI number and GPS connection, a distress alert automatically transmits your identity and position to nearby vessels and rescue authorities.

• Register and program your MMSI.
• Connect radio to GPS.
• Know where the distress button is located.
• Follow with a voice call on Channel 16.

Final Best Practice

Professional communication is calm, brief, and accurate. The goal is not to sound technical — it is to be understood instantly.
