Langstone Harbour is a huge natural harbour accessed through a narrow entrance, which means on the full ebb, the tide races through the narrows like a breached dam. Therefore best avoid arriving on the ebb tide, and the recommended times for arrival is from -3hrs HW to +1hrHW. The marina is tucked behind the drying bank on the port hand side as you enter Langstone Harbour. Call the marina on VHFCh80 call sign ‘Southsea Marina’ for availability and berthing instructions. The entrance to the Southsea Marina Channel is just past the Hayling Ferry pontoon at the end of the drying bank and a marked channel guides you to the marina entrance. Note, only the port hand beacon piles are lit, and the channel is dredged to 0.5m below chart datum and vessels with a draft in excess of 1.5m should not use the channel at ±2hrs LW.
Traffic Light Signals:
The marina entrance has an automatic tidal gate that rises and falls according to the actions of the tides, and the traffic lights at the gate doesn’t quite conform to the logic that some might expect. The tidal gate system automatically maintains a constant 2.4m of water in the marina and at the top of the flood tide the marina is ‘free flow’ for traffic! The red and green lights at the tidal gate indicates if the tidal gate is up or down - THEY ARE NOT USED TO CONTROL TRAFFIC!
RED - means the tidal gate is up. No access
GREEN - means the tidal gate is down. Access is allowed and note there’s a tidal gauge both inside and outside the marina indicating the water clearance above the gate.
