In this new expanded edition of Brown's Tidal Streams, which has been completely revised using the most up to date information available from the Hydrographic Dept., the charts show how the tides are running at any hour round the British Isles and the North Sea. It is essential for safe navigation that great care be taken at all times to be aware of and allow for the effects of tidal streams on the performance of a vessel. This book has been compiled to assist in this matter and its value will he properly accounted for if its content is applied in relation to the navigation and safety of a vessel. There are over 70 larger scale diagrams of tidal streams in the North Channel, Sound of Jura, Pentland Firth, The Humber Approaches and the Bristol Channel.
