THE FIRST HYDROGRAPHIC CHARTS OF GREAT BRITAIN. Originally published in Greenville Collins' "Great Britain's Coasting Pilot Being a New Survey of the Sea Coast" with two insets, ‘A Correct Draught of Plymouth Sound Catt Water and Ham Owse’ and ‘A New Draught of the the Isle of Wight’. At the center of the map are instructions for use, “In this Channel Draught the smaller figures are the Depth in Fathoms. The Litteral or Roman Figures then shew ye Hour of High-Water, or rather ye End of the Stream that setts to ye Eastward, on ye Day of ye New & Full Moon. Add therefore ye time of the Moons Southing or Northing to ye Number found near ye where yor Ship is, and ye Sum shall show you how long ye Tide will run to ye Eastward. But if it be more than 12 Subtract 12 therefrom. The Direction of ye Darts shew upon what Point of ye Compass ye Strength of ye Tide sets. All Masters of Ships and others, who shall have opportunity to observe ye Depths, with Certainty in respect of ye Place, are desired to communicate them to ye Publisher hereof.”
Captain Greenville Collins was appointed to the position of His Majesty’s Hydrographer by Charles II in 1681, and was commanded to “make a survey of the sea coasts of the Kingdom by measuring all the sea coasts with their exact latitudes, the true plots of all harbours, rivers, roads, bays, creeks, islands, soundings, and the setting and flowing of tides’ which he surveyed over the course of seven years and finally published in 1693 (Hyde 2009).
