Channel Lightvessel was the name of a lightvessel station located in the English Channel between 1979 and August 2021, when it was replaced with a lighted buoy. It is also one of the 22 coastal weather stations whose conditions are reported in the BBC (Met Office) Shipping Forecast - the weather station is still announced as Channel Lightvessel Automatic despite being replaced by the buoy, as of 2025[update].[1] The vessel's position was Lua error: callParserFunction: function "#coordinates" was not found., approximately 56 km (35 mi) north-northwest of Guernsey.
The lightvessel marked the western end of the English Channel Traffic Separation Zone.[2]
Signals
[edit | edit source]The light, on a 12 m (39 ft) tower, had a range of about 15 miles, and flashed for .3 seconds every 15 seconds. The fog signal gave a single 2 second blast every 20 seconds. The agile radio beacon transmitted the letter "O" in morse code on X band and S band frequencies for nine seconds every thirty seconds.[3]
History
[edit | edit source]The Channel lightvessel was established in 1979 as part of the Off Casquets Traffic Separation Scheme (TSS), introduced following the 1978 grounding of the Amoco Cadiz.[4] The lightvessel was intended to give clear definition to the TSS, as such schemes were at the time a new feature, rather than marking a physical hazard to navigation.[4]
In May 2021 it was announced that the vessel would be replaced by a Type 1 buoy in August 2021.[5] In August 2021 Trinity House stated that the replacement had been completed,[6] with the Channel Lighted Buoy being deployed by THV Galatea.[7][8] The light vessel was towed away by THV Patricia.
Channel Light Buoy
[edit | edit source]The light on the buoy flashes every 10 seconds. The agile radio beacon transmits the letter "O" in morse code on X band and S band frequencies for twenty seconds every sixty seconds.[9] The light is an LED with a range of 9 nautical miles.[10]
