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.
Please note one other correction:
Page 8: Table of Routes. In the list of Sectors for Ramsgate to the Crouch via the N. Edinburgh Channel. Please amend Sector B4 to read B5 (both North and Southbound). A similar amendment needs to be made to the Schedule of Routes and their Sectors at the back of the book.
Other Downloads
There are five downloads currently available:
1. Data on depths at the Sunk Sand between the SW Sunk and the Middle Sunk. This data is from soundings on 1st July, 2010 and is currently incomplete. I hope to add further detail shortly subject to the settled weather continuing. In the meantime, this chartlet may be of use for half tide crossing.

2. Data on depths at the Spitway (June, 2009 and July 2010). The download is a pdf file containing a plan, text and photographs.

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.

New for 2010 -
New Sectors for Princes Channel added, providing 10 New Routes
Including Essex Rivers to Ramsgate via Princes Channel and links to Sea Reach No. 1 for timing your arrival at the start of the Thames
Following a request from a reader, I have added eight new sectors in this supplement which will enable you, when linking these sectors with those already in the book, to add ten new routes. For those of you without the book, I am afraid you will find these tables incomplete!
The new Routes are:
- Ramsgate to each of the Essex Rivers via the Princes Channel and the Swin – this avoids the necessity to cross the Sunk Sand but does add the certainty of some adverse tide somewhere in the passage and a little extra mileage.
- Ramsgate to Medway via the Princes Channel – this avoids the shallow Hook Spit.
- Ramsgate to Thames (Sea Reach) – for those planning a trip up the Thames.
- Each of the Essex Rivers to Thames (Sea Reach).
- Each of the Suffolk Rivers to Thames (Sea Reach) via the Spitway and Swin.
This at the time of writing, as the Nore Swatchway is closed and as there was space for an extra sector in the table, I have added data for the Medway Landfall to Sea Reach. Subject to demand, it would be possible to add two or more sectors to cover the Queens Channel route from Ramsgate to the Swale and Medway. Let me know if this is of interest.
New for July 2010
