About Dielette Port
Port with almost permanent access on the west coast of Cotentin, port shelters before the passage of Raz Blanchard. Marina with fishing, trade and passenger traffic activities to the Channel Islands. 18 MN from Aurigny, 30 MN from Cherbourg, 28 MN from Guernsey, 36 MN from Jersey. The harbour is reasonably 24-hour access but best check with the Marina Harbourmaster. The outer pontoons can be used for mooring (but there may be a swell) and can also be used to increase your arrival/departure times. The most useful page – www.cc-lespieux.fr/fr/port-die… When there was 1m of water at the shallowest point of the harbour entrance, the depth at the pontoon in front of the Dielette harbour office was approx 1.9m. A Guernsey Chart Datum of 2.5m would give about 1m at the entrance of Dielette harbour in 2010. Boats having a berth in Guernsey have a 50 % discount on the mooring fees during all the year, except June, July and August. Jersey boats have a 50% discount all the year except on Friday, Saturday, and Sunday nights. Dielette is a very pleasant marina and often has space available when Carteret is full. Only 20 mins from Carteret by car/taxi (approx Euro50) and 30 mins to Cherbourg. Dielette is the closest French marina to Guernsey. The marina staff do not come out to provide guidance but stay in their marina office. No village or town close by and so not much to do unless you have a car. There are pontoons in the harbour where you can moor if the tide is too low to get into the Marina. If the wind and / or swell is from the North West, then you can get quite a bad surge in the outer pontoons and in the marina when the tide is over the sill. It is amazing the effect it has on the boats and can be quite uncomfortable. You cannot get in the harbour at all tides as it has silted up, so beware. Also – be careful near the wall of the marina on the harbourside, there is a big sill. https://apisspl.kpratik.com/storage/uploads/2025/01/21/APPD_Guide25-1.pdf
