General Description

Langstone Harbour is a large tidal Bay lying between Portsmouth to the West and Hayling Island to the East. It is a "Internationally Important Wetland" , and wildlife flourishes in the extensive, somewhat desolate mudflats and navigable channels. It is approached through a narrow entrance through which the tide can ebb at a surprising rate. ... read more


Langstone is safe to enter in moderate conditions but for first timers it is probably best to avoid going in on an ebb tide, especially springs. Onshore winds combined with Spring ebb tides can kick up rough, and the entrance shouldn't be attempted at all in southerly or south-easterly gales.

Approach is made between two shingle banks, Western Winner to the West and the far more extensive East Winner to the East. Pilotage details for the approach to Langstone are now given:

Depths in the approach range from 1.2 m at LAT upwards, so consultations with the tide tables will be required. ... read more

Berthing, Mooring & Anchoring

Once  through the narrow entrance there are a couple of mooring opportunities for the visiting yachtsman or motorboater.  Southsea Marina is just within on your port side.  This is covered shortly, with current prices.  Yacht club moorings (with permission), harbour moorings when, occasionally, available, and anchorage (with permission)  complete the picture here.  These options are now covered:

There is a strict 10 kn speed limit within the harbour, other than in the designated waterskiing area. ... read more

Update Spring 2016
Written by dononshytalk | 9th Mar 2016
These notes were reviewed by Don in March 2016. The availability of visitors mooring outwith the Marina is unclear so a call to the harbour on VHF will be needed to clarify on the intended day.
ECA moorings
Written by Bailingben | 2nd Feb 2016
The ECA visitor moorings are deep water and on your port side in the 'RUN' when entering , the only issue with these moorings is that they are vulnerable when a southerly or northerly wind picks up and you end up with a wind against tide situation.

The other issue is the fishing boats do a very interesting 10 knots and make a big wash with isn't very fun to be hit by side on. The first mooring in the row which is the one closest to the slipway is a short stay only mooring, all the others are 24 hour moorings.

hope this helps.

Update March 2014
Written by dononshytalk | 31st Mar 2014
This site was reviewed March 2014. Harbour dues and Marina charges have increased for the 2014 season and these have been edited. We also note that,although the harbour no longer maintains any visitors moorings, they will rent out any spare moorings if they are available. We have also noted that the water-skying area based on the Langstone Channel is delineated by yellow buoys
