The principal ferry operated between West Tilbury and Gravesend and was under the ownership of the Lord of the Manor of Parrock in Milton-next-Gravesend. A sketch-map of 1571 shows evidence of two jetties, the one on the north bank leading to a northward road crossing the marsh. There are also houses marked on the marsh itself, which was important for sheep grazing; and there is some evidence to suggest that the ferry was used for the cross-river transport of animals and wool.
