Crossing the Thames Estuary

Third Edition, available at

The Third Edition has with all the popular content fully revised - routes, waypoints, descriptions, chartlets AND wholly new - quite different - Passage Planning Tables.  These are now simpler and provide you so much more information.

An indispensable companion for planning Thames estuary passages, this book provides you with everything you need to plan your passage across the Thames Estuary.

The book provides you with guidance on the choice of route, variously between Ramsgate and the Kent, Essex and Suffolk Rivers.  In the Third Edition, route guidance is provided for 60 routes, including the ‘outside’ route between Ramsgate and Harwich Harbour and the Deben.  Each chapter provides all the data - distances, sectors, waypoints into one convenient place including the ‘rolling road’ for each route ready to be open on the chart table during your passage.

The new tables are a major development based on the original data but needs no calculations: it provides the results every 30 minutes of the day, for each route, northwards, southwards, Springs or Neaps at 4, 5, 6 or 7 knots boat speed.  You just make the choice.

A consolidated update, issued as required, keeps this book entirely up-to-date.
