This product is intended as a guide for racing and is in no way intended to replace normal navigational measures or good seamanship. Whilst every attempt has been made to ensure the accuracy of the data, it must be recognised that tide flows change with sea bed movement and rates and direction differ between neaps and springs. The authors in no way warrant the accuracy of the data. Navigating in reduced depth water is inherently dangerous. It is vital to constantly monitor depth readings at all times.
Important when using this book. The back drop is not a chart or map but simply a distorted back drop to enable you to ascertain where the flow readings were taken. We recommend the use of this flow data book alongside a navigation chart.
