I need to give a warning regarding the SW Sunk (forgive me I've caught the lurgy today pretty bad so the NtM will wait for the morning).
But! I have had information from a couple of yachtsmen this month - who specifically independently tried the SW Sunk swatchway on th 6th and 17th March. On each occasion a serious spot of shallows was just on or south of the rhumb line between the waypoints. It may be that the swatch has migrated north-east and it is possible to cross a few hundred yards further that direction but there is no data at the moment.
I will be re-surveying but it will be early May before I can do it (wooden boats need warmth to be painted - and I am fettling some woodwork at the moment). I shall ask the PLA if there is more information recently but I suspect there isn't. Incidentally the PLA has supplied their 2015 survey of the Middle Sunk area. I've drawn the chartlet and frankly the Middle Sunk based upon 2015 isn't the best. It is possible but a little brave - the swatchway wanders like a dislocated dog's back leg and close to the unmarked wreckage of the old Sunk Beacon and a drying area right north of where we would have wanted to head!) So not recommended to use either the SW Sunk or the Middle Sunk until tried. The Little Sunk crossing has been successful and traditional that is pretty stable.
I'll add the Middle Sunk chartlet tomorrow morning which is perhaps interesting.
The NtMs this week are not critical for leisure craft - reduction of soundings around the Goodwins (which would have been too close anyway) and the TSS which is quite deep enough, a River Stour - Erwarton Ness S - Anchorage area warning and River Thames - Coalhouse Point SE - Depths. On the locals, Harwich is doing the seasonal marks. I'll catch up in the morning but I'd rather get an early night (even the cat doesn't want me).
