Visitors making for the Littlehampton marina must give advance notice to the harbour master no later than 1630 hrs the day before you intend to arrive, in order to access the footbridge.
The River Arun is protected by a bar across its entrance which dries to 0.7m and therefore restricts the access to ±3hrs HW for a vessel with a 1.5m draft. In strong SE winds, the entrance becomes dangerous with a considerable swell running up the river. There is a training wall, which stretches out to the south and crudely follows the line of the East Pier and gradually curves away to the East. It covers at half tide, however it is marked by several perches. The gap between the East Training Wall and the West Pier is narrow and at the end of the West Pier is a tide gauge whose indicted depths are referenced to chart datum which means one has to subtract 0.7 from the indicated depth.
At night, the narrow channel is navigated by using the leading lights, bearing 346°, front light; FG on black column at end of East Pier, rear light: Light House Occ.WY.7.5s at the root of the East Pier.
