Eventually on Wednesday no easterlies so I got down to the swatch. Unfortunately Gladys was unavailable so it was a busy day alone.
Good news: It is still there and well established as several readers had already found this season. There is a new chartlet available for download as jpg (click on the image) or pdf (click on the button) Downloads. The 2022 waypoints are still usable this year. On the Middle Sunk side depths improved 0.5m to 1.0m. The Middle Sunk side remains quite nice and gradual.
Not so good: The SW knoll has migrated slight to the north which moves it closer to the track between the west and midpoint. The northern edge of the SW knoll remains very steep and can have a mild tide rip on the latter part of the flood. Basically the flood through the swatch from east to west collides with the flood of the Barrow Deep, hence the steep edge. All rather like the M2/M25 junction - always agitated
. I estimate the migration north is about 50-75m. Normally I would be suggestion the west and mid waypoints get moved a similar distance. BUT
Bad News: On one of the runs over the 'edges' of the Middle Sunk, I glanced over at the Humminbird side scan and as we passed I saw a 'summat' for 3 or 4 seconds. Downloading the record I found this:

In those few seconds live I though it like a floating line that was trying to reach the surface. However, the record suggests it is more substantial. I shared the images to the PLA and they reported a check survey earlier this season suggested that 0.5m to 1.0m of sand had been uncovered. The implication is that the natural removal of the sand has exposed a wreck or other debris. It is good news that the PLA already had plans for a 100% survey for that part of the swatch later this year so we should get more information. The PLA are very helpful and supportive people.
Unfortunately it is impossible for me to estimate the depth clearance over the 'summat'. The 25 on the scale on the image indicates that the object was 25m away from me as I passed. At the spot I passed there was 3.7m at Chart Datum. The location is 51.38'406N, 001.17'293E. I have marked the location on my chartlet as a 'dangerous wreck' in the absence of positive data. The track between the west and mid point waypoint is pretty equidistant between the 'wreck' and the shallow edge of SW knoll. I estimate the equidistant as 185m each way. The swatchway is already a 'GPS route' but a good plotter will be helpful.
It is a shame that the depth clearance cannot be established but as soon as I get more information I will of course update readers and forumites.
