Information to be Logged 1 1. Time tasked by JRCC 2. Details of information supplied by JRCC 3. Time away from dock 4. Last known position of search object 5. Description of search objects 6. Time on scene 7. Time, position and type of search pattern 8. Weather, visibility, sea and swell
Information to be Logged 2 9. Tide and current 10.Information on distressed vessel 11.Name and address of operator 12.Persons on board 13.Vessel license or registration number 14.Type of assistance supplied 15. Distance towed 16. Disposal of vessels/ persons recovered

VHF Radios All volunteers with the CCGA are expected to have their Radio Operator’s Certificate.
VHF Radios Off/ On/ Volume Squelch DSC Frequency Selector High/Low Power Mode Transmit
VHF Radios Squelch - adjust the receiver sensitivity and limits unwanted radio noise. Too high a squelch will result in weaker signals not being heard. Channel/ Mode - Keep the radio in USA/CDA mode at all times. Simplex channels transmit and receive on same frequency - duplex send and receive on different frequencies.
VHF Radios Hi/Lo - this control the power with which the VHF will transmit. High is generally 25W whilst Low is about 5W. Handheld VHFs have a high of about 5W and a low of about 1W.
VHF Radio Procedures Use Channel 16 for calling only, except for MAYDAY. Monitor at all times. Name the station being called x 2, followed by the calling stations name or call sign x2. Always identify yourself when calling. Use standard marine language and vocabulary
VHF Marine Language Over Out Roger Wilco Channel Say again I say again Standby All after Word after All before Word before Affirmative Negative That is correct Correction Read back I spell Break Seelonce Seelonce finis
Phonetic Alphabet Because it is easy to confuse the sounds of some letters, when spoken over a radio, their phonetic equivalent is used instead.. AlfaBravoCharlieDelta EchoFoxtrotGolfHotel India JuliettKiloLima MikeNovemberOscarPapa QuebecRomeoSierraTango UniformVictorWhiskeyXray Yankee Zulu
Communications 1 Think before you speak Key the microphone for 1 second before speaking Keep messages short and to the point Use a working channel - not Channel 16 Check the channel is clear before speaking Keep microphone about 2 inches from the mouth
Communications 2 Talk in a calm and clear voice Do not use offensive language Preface all distress calls with distress signal Use proper words and expressions Spell names phonetically Say numbers individually Do not “on air” for prolonged periods
The Global Maritime Distress and Safety System applies to all vessels of 300 gross registered tons, or carrying passengers on international voyages
Distress Communications Sea Area A1 Within range of shore-based VHF DSC coast station (40 nautical miles) Sea Area A2 Within range of shore-based MF DSC coast station (excluding sea areas A1)(150 nautical miles)
Distress Communications Sea Area A3 Within the coverage of an Inmarsat geostationary satellite (approximately 70°N to 70°S) (excluding sea areas A1 & A2) Sea Area A4 The remaining areas outside sea areas A1, A2 & A3 (polar regions)
All Emergency Position Indicating Radio Beacons (Marine), Emergency Location Transmitters (Aircraft), and Search and Rescue Transmitters transmit on either 121.5 or 406MHz EPIRBs all have their own unique identification number.
EPIRBs Emergency Position Indicating Radio Beacons Automatic EPIRBs will float free and be activated by water Manual activation will require removal from their brackets and activated.
ELTs Emergency Locator Transmitters are fitted to aircraft and also transmit on 406 MHz
Procedure for Channel 16: 1. Transmit an alarm signal. 2. Say “MAYDAY, MAYDAY, MAYDAY”. 3. “This is RCM-SAR 13, RCM-SAR 13, RCM- SAR 13”. 4. Give vessel position be latitude/ longitude of bearing and distance from identifiable point. 5. State the nature of distress and assistance required.
Distress Messages 6. State number of persons on board, injuries and other vessels involved. 7. Describe your vessel. 8. Provide any other pertinent information to assist rescuers. 9. REPEAT, say “Over” and listen
Distress Messages Imposition of Silence “SEELONCE MAYDAY” Finish of Mayday “MAYDAY FINIS” Urgency “PAN, PAN” x3
Distress Messages If you are underway and you hear a distress message and no-one else answers, answer the vessel, gather and log all information given, and pass information to Joint Rescue Coordination Centre or Marine Communications and Traffic Services.
