Description 
Summary

Co-tidal and co-range charts show lines of equal range and equal times of tides, or data of harmonic constants, for certain areas around the United Kingdom. Two charts cover the area from Dungeness to Hoek van Holland and the southern North Sea. A third covers the British Isles and adjacent waters. The charts are drawn using all the available tidal data, and a knowledge of tidal theory to assist in the necessary interpolation. The reliability of these charts depends on the accuracy and number of tidal observations taken in the area concerned. Since offshore sites for tide-gauges, such as islands, rocks or oil rigs, are seldom suitably placed, offshore data will often depend more on interpolation than that for inshore stations.
