Precautionary areas for all vessels
A precautionary area for all vessels exists off St Helier. Mariners navigating in the precautionary area should do so with extreme caution as vessels with limited manoeuvrability may be encountered.
Live submarine electricity and telecommunications cables exist in local waters and come ashore at the following places:
- the east coast at Archirondel
- the west coast at Le Braye
- the north Coast at Greve de Lecq
Numerous other disused cables remain around the Island and in territorial seas, which are marked on current nautical charts.
Mariners are advised to avoid anchoring in areas that are in close proximity to any cables, whether live or not.
If weights are excessive and you suspect that you have become attached to a cable, the following action should be taken:
- do not endanger your vessel and crew by attempting to recover your gear
- carefully plot your ship’s position as accurately as possible
- advise Jersey Coastguard of your situation on VHF channel 82 or telephone +44 (0) 1534 447705
Mariners are prohibited from anchoring in the following areas:
- designated shellfish beds off the Island’s east coast
- the parallel box running from Archirondel to the French coast (fishing activity is also prohibited)
You are strongly advised not to anchor within the precautionary area to the south of St Helier Harbour, or any of the boat passages, approach channels or within harbour confines. Each of these areas is marked on current nautical charts.

General Direction No: 2
Speed Limits in Harbour Areas
1. No person shall drive or permit a vessel to be navigated in a harbour or the fairway of any harbour (see GD8) at such speed as may cause or be likely to cause the wash from the vessel to do damage to any other vessel or to any property. At no time shall a craft be permitted, within any harbours to proceed at a speed greater than five knots, except as identified below.
2. St Helier. The five knot speed limit in paragraph 1 above applies to vessels operating within an area northwards of a line between the south-west arm of the La Collette Harbour Tanker Berth and Elizabeth Castle Hermitage and south eastwards of the line joining Fort Charles Slipway and West Park Slipway. Elsewhere within St Helier Port Limits (including the approach channels and the precautionary area) the 5 knot restriction does not apply, except for inshore areas referred to in GD 1.
3. Gorey Harbour. The five knot speed limit applies within the harbour from a position abeam the pier head assessed for a vessel entering or departing on the main charted approach channel. To seaward of the Pierhead, the speed limit does not apply.
4. Les Écrehous. GD 1 limits the speed of PWCs to five knots anywhere in the vicinity of Les Écrehous where the charted depth is less than 10m. For other craft, the general speed restrictions limiting speed within a harbour to five knots, do not apply. However, mariners are advised not to create excessive wash when passing vessels moored or people on the coastline/beaches.
5. General Safety. In harbours where recreational sailing is conducted under supervision, safety boats involved in the management and training of these marine activities may exceed the speed limit, but only when required to ensure safety. These activities have been identified as taking place within the limits of St Catherine's and St Aubin's harbours.
Granville Bay Treaty
The Granville Bay Treaty is a trans-boundary management framework between the Jersey and French governments. It provides for shared fishing rights and management over the Granville Bay area (outside the exclusive three mile limits) and divides the area into management zones.
The Granville Bay Treaty is principally managed by Government of Jersey departments rather than the Port of Jersey.
UK managed treaty
The UK Fisheries Management Agreement sets Jersey’s relationship with the UK.
This agreement is managed by Government of Jersey departments rather than the Port of Jersey.
Port restricted zones
Information about the restricted zones can be found in the 'Port restricted zones' document.
