63 routes with full passage tables An indispensable companion for planning Thames estuary passages, this set of tables enables navigators to select the best routes according to tide times. A set of tide tables, IMRAY charts, East Coast Pilot & Crossing the Thames Estuary provide all the information that is needed to fully explore the estuary & coasts of Suffolk, Essex & Kent. The object is help you plan your journey across the complex waters of the Thames Estuary quickly, safely, easily & accurately. To do this a series of tables is provided based upon a variety of routes with alternative tables for Springs & Neaps & for a choice of average boat speeds of 4, 5, 6 & 7 knots. As with the first edition, the concentration is on the `inside` routes that weave through or across various sands & swatch ways. However, this edition now
Includes:: the `outside` route between the Suffolk Rivers & Ramsgate. The Time Planning tables will enable you to plan departure times to arrive at key points on the crossing at your chosen time. The purpose is to provide the reader with a simple & accurate way to determine the best choices when making the crossing: what is your preferred route? What time do I start to ensure sufficient water through swatch ways or over banks? What is the best compromise to get the most help from the tide & still have sufficient water over the banks?
