Precise details of timings, tide state, etc will have to wait another day but inbriefand roughly ...
We crossed between the waypoints given in Crossing the Thames Estuary at roughly low water - ish on a neap tide
From the book, chart and survey PDF off the accompanying web site, I was expecting at least 2.4m over CD plus the height of the tide ( which I didn't worry about factoring in as we only draw 0.9m)
Almost as soon as we turned at the Barrow Deep waypoint we encountered far less water than expected. In the area where the chart indicates over 3m*and the PDF indicates at least 2.4m, the depth sounder dropped to between 1.2 and 1.5 m for some way and briefly as low as 1m at one point before rising to around 2 to 2.5m for most of the way to the Black Deep waypoint
At about the hall way point, with 2.0m on the d sounder, the starboard keel bumped and graunched over something just to keep my nerves on edge
Our sounder is ( deliberately*) not calibrated and is located roughly 0.2m below the waterline ( it's under the bridge deck so this does rather depend on how many people are in the cockpit and how much beer is stashed under my bunk!) so add that to the depths above
Despite the huge tidal advantages (a fair tide for all but the last 5 miles or
so all g the way from Fambridge to Ramsgate), I wouldn't attempt the SW Sunk crossing at anything much less than half tide,
That's all from sunny Ramsgate!

at HW. I am kind of looking at Wednesday 29th or Thursday 30th weather permitting. I know it's further but don't forget that the crossing point over the Little Sunk (near the Barrow No 2) seems to be pretty stable.
