  1. Communications Afloat Chapter 3 Section 12 America’s Boating Course3rd Edition >>

  2. Communications Types • Distress • Emergency calls • Safety communication • Working • Port communications • Ship-to-ship communications >> 2

  3. Radio vs Telephone • Cell phone • May be used to contact local law authority • Value at sea is limited • Coast guard can not find position • Transmission power of only 3 watts • Other boater in vicinity will not hear you >> 3

  4. What is Marine VHF Radio? • Primary Radio for Coastal and Inland Boaters • NOAA Weather Forecasts • Summon Assistance • Communication - other boaters, shore facilities • Up to 25 watts of power >> 4

  5. Channel Allocation • VHF radio is not required • Highly recommended for safety • If radio is turned on – MUST monitor • Channel 16 – distress • Channel 9 – calling channel • Working channels • 68, 69, 71, 72, 78 >> 5

  6. Radio Range • Line of Sight • 25 NM (typical maximum range) • Actual Range based on: • Height of antenna(s) • Transmitted power >> 6

  7. Equipment – Fixed Mount Separate Antenna – higher 25 Watts (Transmit Power – high) 1 Watt (Transmit Power – low) All new models equipped with Digital Selective Calling (DSC) >> 7

  8. Fixed Mount VHF Radios Courtesy of ICOM One Button Distress (DSC Function) Microphone with Transmit Button Channel Selection Up/Down On/Off Volume Channel 16/9 Button Button to Select Weather Channels High/Low Power Switch Squelch >> 8

  9. Equipment -- Handheld • Integrated Antenna (Rubber Ducky) • Lower height - less range • Lower Transmit Power – less range • 5-6 Watts –High Transmit Power • 1 watt -- Low Transmit Power >> 9

  10. Handheld VHF Radio Antenna On/Off Volume Speaker/Microphone Weather/ Radio Squelch Control Channel Selection Up/Down Power High/Low Key Channel 16/9 Instant Select Scan >> 10

  11. Licenses -- Recreational • None Required If … • Operating in U.S. Waters • Boat LOA < 20 Meters (65 Feet) • Required If … • Travel to Foreign Ports (Canada, Bahamas, Mexico, Etc) • Communicate With Foreign Stations >> 11

  12. Licenses -- Types • Obtained from the FCC • Station License for Boat (radio) • Restricted Radio Operator's Permit • Required for each operator >> 12

  13. Operating Procedures • Where Used: • Only on boats • Land operation requires special license • Limited to Essential Communications: • Summon assistance • Safety purposes • Needs of the vessel >> 13

  14. Channel Allocation >> 14

  15. Digital Selective Calling • Channel 70 – digital • Signals other radios • Sends position via GPS • Radio registered to owner • MMSI number part of call >> 15

  16. Routine DSC Calls • DSC not just for Emergencies • Routine calls to a specific vessel (MMSI) • Routine calls to a shore facility (MMSI) • Group Calls (based on pre-defined MMSI) • You pre-select working channel • Other radios auto switch to that channel for voice • Audio Signal • Sounds only on selected recipients’ radios >> 16

  17. Digital Selective Calling Why Is DSC Important To Me ? • SOLAS Vessels No Longer Required to Monitor Ch 16 • May miss your voice distress call • USCG Rescue 21 Program • Modernization of USCG Coastal Com Facilities • Fully Operational by 2011 • All 655 USCG Vessels with VHF/DSC by 2007 • Takes the "Search" out of Search and Rescue >> 17

  18. Rescue 21 WAIT Animated >> 18

  19. DSC Distress Calls • Emergency Only • Press & hold red button • Sounds alarm on DSC radios • Response switches to Channel 16 • Can enter type of distress code >> 19

  20. Language • Use appropriate ‘radio’ terms • Skipper responsible for radio • Criminal offense: profane or indecent language • Felony: false distress calls • Don’t allow children to play with radio >> 20

  21. Procedure Words (1) • THIS IS Preface to your call sign • ROGER Last transmission received OK • OVER I’m done, you can (talk) answer • OUT I’m done, Goodbye • WILCO ROGER and I will comply • Tips: • Always end transmission with OVER or OUT - NOT BOTH • Do not use “Roger Wilco” instead of “Wilco” • “Wilco” means “Last transmission received OK and I will comply” >> 21

  22. Procedure Words (2) • WAIT I will be back in a few seconds • SAY AGAIN Say that again • CORRECTION Oops! I really meant to say • AFFIRMATIVE Yes • NEGATIVE No >> 22

  23. Emergency Calls • Mayday • Pan-pan • Securité • Responding to emergency call >> 23

  24. Mayday • For assistance with immediate danger to life and property • Examples: • Life-threatening medical • Person lost overboard • Boat sinking • Boat on fire >> 24

  25. Mayday Info • Location • Nature of distress • Description of boat • Number of persons aboard (injured) • Seaworthiness of boat >> 25

  26. Mayday Call MAYDAY, MAYDAY, MAYDAYTHIS IS SAILBOAT WINDSONG, WINDSONG, WINDSONG. MAYDAY WINDSONG. OVER VESSEL CALLING MAYDAY - THIS IS COAST GUARD STATION CORTEZ. WHAT’S THE NATURE OF YOUR DISTRESS AND YOU POSITION. OVER. THIS IS SAILBOAT WINDSONG MY POSITION APPROXIMATELY 5 MILES OFF EGMONT KEY - COMPASS BEARING 120. SLOWLY SINKING. ESTIMATED FLOAT TIME ONE HOUR. FOUR PERSONS ABOARD, ONE INJURED, FRACTURED LEG. WE ARE 25 FOOT SAILBOAT, COLOR WHITE WITH BLUE TRIM. WINDSONG: OVER. Loud Audio to Follow SAILBOAT WINDSONG THIS IS STATION CORTEZ. VESSEL 42136 IS ON THE WAY TO YOUR POSITION. COAST GUARD OUT. Sound >> 26

  27. Pan-Pan(pahn-pahn) • For assistance when danger does not rise to “MAYDAY” level • Examples: • Out of fuel • Lost in a fog • Unable to control or operate vessel >> 27

  28. Securité(say-cure-it-tay) • For navigation safety messages • Examples: • To report a navigational hazard (sunken object) • Operational signals (backing out of a slip) • Weather Alerts >> 28

  29. Responding • Do not transmit on a channel in use • Maintain silence on channel until clear • If in a position to help - call the vessel in distress - what you can provide • Inform the USCG of your actions >> 29

  30. Routine Calls • Information or logistics • Listen before talking • Use lowest power • Calling channel • Working channel • Keep calls short >> 30

  31. Radio Check • To verify radio works • Use calling or working channel • Limit use >> 31

  32. NOAA Channels • Broadcast weather reports • Includes marine specific data Channel depends on location >> 32

  33. Offshore • High-frequency single sideband • Channels for marine use • Requires license • Satellite • Similar to cell phone >> 33

  34. EPIRBs • Can transmit ID & homing signal • May be water activated Primarily for off-shore use LAST 34
