Marina pontoon berth access:
Access to the marina berths is approximately 1.5 to 2 hours either side of high water, depending on your boat’s draft and if it is spring or neap tides. Our berths drying depth varies between 2.8m to 3.1m above chart datum.
For example, a 1.2m draft boat will need a minimum of 4.3m tide and can access the berths at least 1.5 hours before/after high water.
Deep water basin access:
We maintain a depth of 1.75m inside the pool. To come into the pool we can lower the gate on a 4.2m tide or above, 20 minutes either side of high water. The sill dries at 3.1m above chart datum.
For example, if you are coming in to the pool and draw 1.5m you will need a 4.6m tide to enter.
If you are bringing your boat up to Thornham Marina, please check the tide tables first. Alternatively, please call us on 02392 706 603 for advice and to check the gate opening times for a particular day.
See our video how to approach the marina.
From Chichester Harbour entrance follow the main channel, and head east at Sandy Point, keeping the green Winner buoys all to starboard. At Sandhead port hand marker the channel turns northwards. Keep to the left side of the channel, passing the Camber south cardinal to starboard which lines you up to enter the Thorney Channel.
You are now lined up to come into the holding basin or to turn in towards our pontoons.
If you are coming around to be hauled out, please wait to be called forward into the basin by one of our staff to avoid congestion.
