Guernsey VTS

Visitor Marina

Guernsey VTS is the first point of contact for recreational craft and all commercial vessels using St Sampson's and St Peter Port Harbour. The location of the Signal Station at the end of the White Rock Pier and the monitoring of CCTV assist the VTS Officer in their task of keeping watch on the various activities in the harbour, day and night. All vessels of 20 metres in length or more have to take part in the VTS Service Area. Vessels under 20 metres are strongly encouraged to listen to VHF Channel 12 for traffic movements. CCTV, VHF and telephone conversations are all recorded and can be used in any investigation into incidents within the harbour.

Port entry and exit

Commercial vessels are severely constrained by their draught whilst manoeuvring within the harbour and the approaches and small craft are to be kept well clear. A red light on the White Rock Pierhead, one on the south end of the New Jetty and one on the Inter Island Quay indicate that large vessels are under way and prohibit entry and exit of others except small boats of 15m or less under power, which may proceed keeping well clear. It is also good practice to listen out on VHF Channel 12 for commercial traffic movement.

Speed limits

Speed limits from four to six knots are in force, as shown on the plan of  [pdf icon]  St Peter Port Harbour [172kb]. A speed limit of six knots is in force in most of the bays around the coast of Guernsey and in the approaches to Herm and Jethou. There is also a speed limit of six knots off most of the bathing beaches in Herm and at Rosaire anchorage. Click here for more information.

Radio facilities

Guernsey Coastguard provides emergency cover when required and maintains a 24-hour watch on VHF Channel 16.

VHF DF bearings can also be provided on VHF Channels 16 or 67 (after initial call on 16). The aerial position for D/F purposes is 49˚ 26.27'N, 02˚ 35.77'W.

The normal working frequency of Guernsey Coastguard is VHF Channel 20 (direct calling).

Guernsey VTS works VHF Channel 12.

VHF Channel 12 should be monitored by mariners entering / exiting St Peter Port to be aware of any impending commercial movements and is not to be used for berthing information and general enquiries. 

Routine calls
