HAINAN RACE 2002

RADIO/WEATHER BROADCASTS

 

These notes do NOT form part of the Hainan Race Sailing Instructions, and are issued for information only.

         

RADIO CALLSIGNS

Radio Relay Vessels in charge of radio communications schedules will have the following callsigns (with vessels' functions in brackets):

 

RACE CONTROL ONE : (Yacht Elektra: in charge of the daily morning and evening radio position reporting schedules).

 

RACE CONTROL TWO : (Yacht Dolphin Six: backup for both the daily morning and evening radio position reporting schedules and to relay reports as necessary to Race Control One).

 

RACE CONTROL : in Hong Kong is any vessel designated by the Race Committee to give race information such as postponements, premature starters etc., before and up to 30 minutes after the start of the Hainan Race.   After this, it is the callsign used by the Race Committee representatives in Hainan, who MAY be guarding 4060 kHz and 2638 kHz at the appropriate reporting times and MAY have 2182 kHz and 4125 kHz for distress and calling.

         

RTHK : is Radio Television Hong Kong, which will broadcast special weather forecasts for boats in the Hainan Race on 3940 kHz.  These forecasts, provided by Hong Kong Observatory, will be broadcast at the times shown below.    They will also give detailed weather information for each of the five areas marked A to E on the map overleaf:

Radio Checks/Times:

 

All times in these advisory notes are Hong Kong local time, which is the same as Hainan local time ‑‑GMT/UTC plus eight hours.

         


PLEASE NOTE: Any boat which fails to have a satisfactory radio check recorded and which subsequently fails to report their positions during the Hainan Race is unlikely to find much sympathy in any subsequent protest hearing relating to position reports.


         

PLEASE ALSO NOTE that the radio reporting schedules are being run for reasons of safety, and therefore compliance with them is in your own interests in case of an emergency, quite apart from being required by the Race Instructions.

 

The Radio Operator's Routine:

          

PLEASE REMEMBER TO OBSERVE THE THREE MINUTE SILENCE/LISTENING PERIOD FROM :00 TO :03 MINUTES PAST THE HOUR AND :30 TO :33 PAST THE HALF HOUR. THIS IS AN INTERNATIONAL EMERGENCY REQUIREMENT.

 

Your typical day's radio work is as follows:

 

Morning Schedule

         

·               Run engine to charge batteries.

 

·               Listen to and note down the special weather forecast broadcast by Radio Television Hong Kong (RTHK) at 0533 on 3940 kHz.

 

·               Obtain your boat's 0600 hours position.

 

·               Listen to and use for tuning if necessary the warning call from RACE CONTROL ONE at 0603.

 

·               Give your boat's 0600 position when your boat is called beginning at 0603 on 4060 kHz. A sample call is: "YACHT ALPHA, this is RACE CONTROL ONE, your position please." Your sample reply is: "RACE CONTROL ONE, this is YACHT ALPHA, position two zero one zero, one one four two six, over." You should then hear your position read back, so you can correct any mistakes in reception.

 

·               Remember to give about a one‑second break after pressing your transmitting switch before you start speaking, otherwise the start of your speech may be clipped off by your transmitter's self‑tuning.

 

·               If you can't get through on 4060 kHz, RACE CONTROL ONE will call again for boats not heard the first time after completing the roll. 

 

·               Otherwise, try again on 2638 kHz when RACE CONTROL ONE will run through the list of those boats not heard previously.

 

·               If your SSB is working, at worst you should be heard by other boats that can relay your position. If you know or suspect you have an SSB problem during the race, try calling any other boat on SSB and VHF (Channel 72) to ask them to relay your position.

 

 

 

 

 

Evening Schedule

        

In the evening, repeat the procedure as above but with later times as appropriate ie:

·               Listen to and note down the special weather forecast broadcast by Radio Television Hong Kong (RTHK) at 1745 on 3940 kHz.

 

·               Obtain your boat's 1800 hours position.

 

·               Listen to and use for tuning the warning call from RACE CONTROL ONE at 1803.

 

·               Give your position to RACE CONTROL ONE when called on 4060 kHz.

 

Additional Broadcast Information :

 


All boats are strongly advised to leave their radios on at all other times on SSB frequency 2182 in case emergency assistance is requested by other boats during the race.

 

Other Calls :

               

Before and during the race, information MAY be broadcast on VHF Channel 72 and SSB frequency 4060 kHz.

 

The Race Committee in Hainan MAY keep watch on VHF Channel 72 and SSB frequency 4060 kHz.

         

Advisory calls we may ask you to make, if any, will be detailed during race briefings.

 

If it all goes wrong ...

 

It shouldn't, if your radio kit has been properly installed in a sensible place away from the companionway, and you've had it checked and tested. But it might if you manage to get water over the set - it's easy enough to protect it with a spray barrier comprising a plastic chart cover or something similar. It also might not work too well if you fail to charge your batteries. 

         

If you find yourself without SSB or VHF or both at some stage, for safety reasons alone (let alone what a subsequent protest committee might do in its naturally infinite wisdom) you should resort to communicating your predicament AND your position to other boats by any other means to hand AND log the fact and any signals you make.

 

PLEASE NOTE that if your boat is the one with a radio problem, it is up to YOU to find another boat to tell - leaving aside the dictates of prudent seamanship, good manners and a willingness to help others, we cannot force other boats to drop down or head up from their proper courses to go and have a look at you.

 

The way back:

Because boats return to Hong Kong according to their own timetables rather than in one fleet, the trip home is outside the control of the Race Committee. Also, because ship‑to‑shore communications are covered by Hong Kong Telecommunications International's exclusive franchise, we cannot legally set up a radio base station at the Royal Hong Kong Yacht Club for this purpose.

 

 

 

Those of you who are licensed ham radio operators can, of course, arrange to make your own contacts legally with Hong Kong‑based ham operators at whatever times and frequencies you choose.    

 

While ashore and in the company of other yachties in Hainan or wherever, the most sensible option would be to try to find other yachts returning home at or about the same time as you. Set up your own radio schedules with them at the times used in the race. 

         

If you wish, you can establish an account with Hong Kong Telecom so as to make radio‑telephone calls to Hong Kong : please contact Hong Kong Telecom for details.

         

Race Office representatives in Hainan will keep a list of yachts' intended departure times as they receive them, so that boats can team up for the return trip if they so wish.

              

The special RTHK weather forecasts will be broadcast daily at 0533 from 20th October to 24th October (inclusive) on 3940 for your return journey.
