An anchorage is suggested by the placename marked on an historic Admiralty chart. Lewis Morris's earlier chart for Goldtop Road in St Brides Bay shows the anchorage tucked into the lee of Burrow Head and with a water depth of 3-4 fathoms. Admiraly Sailing Directions of 1870 describe it as an 'indifferent anchorages where a coaster might ocassionally find some shelter? A small vessel may anchor there in 3 or 4 fathoms over sandy ground, about a quarter of a mile E 1/2 N from the head, and ride quietly with the wind to the southward of WSW, but if to the westward of that quarter, she would be much exposed. A current runs to the westward on the southside of the bay, through this roadsted, and by the Stack rocks, for 9 hours, turning about 2 hours before high water on the shore'.
