The Naval chronicle, Volume 16 Edited By James Stanier Clarke, Stephen Jones, John Jones (1806):
From Bulverhithe Point about four miles to the westward the shore is rocky and cannot be used at low water but from thence to Beachy Head there is in general so fine a beach that a landing may be made at any time of tide but an ENE wind would make a considerable sea from Pevensey to Langley Point as the coast trends there much to the eastward but from Langley Point nearly to the pitch of Beachy Head the water would be perfectly smooth Although some spots between Hastings and Beachy are rocky yet they are not to be considered as barriers to a general debarkation in this bay which is spacious and possesses the advantage of having been used with success OB a former occaiion r From Beachy Head to Selscy Hill some partial spots are rocky but an ENE wind makes such smooth water along the coast that the rocks can scarcely be said to prevent any part of it being used for the purpose of debarkation.
