Southsea Cill Gate

Southsea Marina has a cill gate which opens and closes automatically at certain states of the tide. The times of the cill gate opening and closing at Southsea are available in the marina guide PDF file below.

Southsea Marina channel

Please contact the marina on VHF channel 80, call sign "Southsea Marina "when you are approaching the marina channel to be given your berthing instructions. The entrance to the Southsea Marina Channel is just past the Hayling Ferry pontoon. 

  • Seven starboard hand and nine port hand markers mark the approach channel, the first of which are lit piles. 
  • Of the remaining eight port hand markers, the 4th, 6th and 9th are all lit. 
  • None of the starboard hand markers - made up of two buoys and a further three piles, are lit. 
  • The Western waiting pontoon is marked with a starboard hand light.
  • The marina channel is dredged to 0.5m below chart datum, although this can vary and vessels with a draft of 1.5m or more should exercise caution when approaching at LW -2 to +2 hours.
Procedure for entering Southsea Marina

Craft enter the marina via an automatic tidal gate that rises and falls according to the action of the tides.
  • This gives approximately 6 hours of access per tidal cycle. 
  • Please be aware the red and green lights at the marina entrance show if the tidal gate is up or down. They are not used to control traffic. 
  • Red Light - Tidal gate up. No access. 
  • Green Light - Tidal gate down. Access allowed, but check the gauge outside the marina to ensure that there is enough water depth to give you clearance. 
  • The tidal gate uses the laws of buoyancy. When the water outside the marina is level with the top of the tidal gate the weights connected to the gate and the tidal gate itself are balanced. When the sea level rises the weights become (relatively) lighter allowing the tidal gate to lower. This continues until it eventually lies flat. At this point there is 1.6m depth of water over the tidal gate and a green light will be displayed at the marina entrance.
  • Any vessel with a draft over 1.6m should wait until the tide has risen further before entering the marina. As the tide goes out the gate rises because the weights attached to it become (relatively) heavier and therefore pull up the tidal gate. The automatic tidal gate ensures water depth in the marina stays at 2.4 metres for the deeper berths, dropping to 1.3 metres around the edge of the marina for vessels with a shallower draft.
  • The marina entrance is 7 metres wide.
  • When entering the marina, the vessel travelling with the tide takes priority over a vessel travelling in the opposite direction.
  • Please be aware tidal gate times are always approximate and can be affected by weather conditions and air pressure. 
  • There is an outer waiting pontoon adjacent to the marina entrance for vessels waiting to enter the marina if the tidal gate is up or there is insufficient water.
Marina staff are happy to move boats permanently berthed in the marina to or from the waiting pontoon free of charge, Monday to Friday and with 24 hours notice.
