Saturday 13 October heading west from Langley Point near Sovereign Harbour past Eastbourne to Seaford. The distance is 11 nm. There are possible emergency get outs at Eastbourne, Birling Gap and Cuckmere Haven. This will be the day after a spring tide, and the stream will be West-going from about mid-day, so I think it will have to be a one way trip involving a car shuttle. Sunset is at about 1815. Average sea water temperature at Eastbourne last October was 16.1 degrees C.
