Updates for the Book
There is currently one update available which you can download here or from the Imray Web Site.
This provides details on changes affecting the text, some recent valuable experience of depths over the Sunk Sand at both the Barrow No 2 crossing Point and the Sunk Beacon (July 2008) and updates to Southbound table B for 5, 6 and 7 knots and the Eastbound Table E for 4, 5, 6 and 7 knots. For greater accuracy these should be used instead of the original pages.

Remember to set your Printer to ‘Landscape’
The Thames Estuary we enjoy is constantly changing:
- Buoyage is now solely for shipping and altered for their needs and not ours;
- Many fixed marks are not maintained and are crumbling;
- Depths alter both after poor weather and naturally over time;
- Tide data out of the main channels is patchy.
As a result it will benefit all of us to keep as up to date as possible.
