Got into marina with 200mm under the keel at the thinnest parts; Hoo marina since you ask, there's still a few who take their boats out. Scare em to death on the Hamble, I'd guess.
Pushed it too much after Bee Ness though. Extended a tack to get a better slant past Kingsnorth and ended up with minus a foot over a spit. Gulp! Must have got away with it cos of angle of heel.

For much of the East Coast the water is just slightly thinner mud, and the mud is just slightly thicker than the water. Your keel might have been dragging through the soup (or your echo sounder is dicky!).
 
Echo sounder should be tickety boo; set it up when dried out on scrubbing dock and I'd made the tide gauge ( I'd claim accurate to a cm)

Yes, may be fine on a firm bottom and no water flow, but they get confused with mud because there can be no clear boundary between liquid and solid, especially if there's any flow stirring it all up.
 
Brittany this August.
5NM offshore. Took some time to get used to it, kept thinking the decimal point was on the blink.

We had more than 200 m just a few hundred metres offshore a few months ago - Norway Oslo fjord.

For an East Coast sailor, where we usually tack when the depth drops below 3 m, and never seeing the bottom, then seeing 15m through the clear water, and that's directly next to the rocks - you need a new set of expectations!
 
Good to see the pic of the buoy again.
I was bumbling between Madeira and Azores last year; 4000 metres everywhere except for the odd seamount, some of them up to about 100 metres. Ooer, we thought, we'd better keep clear of them - hang on that's a whole hundred metres. So adjustment back to depth in inches seems to have gone OK
 
Try the west coast of Scotland! You can b within spitting distance of the rocks( northwest corner of Bute, near the Maids of Bute springs to mind) and still be in 50 metres!

Reminds me of my ancient echosounder - when the depth got over 20m the decimal point jumped backwards and we thought we were in 2m! Panicking until we realised we couldn't touch bottom with the lead line(first time it had been used). I now have a reliable echo sounder.
 
My current Nasa depth sounder just says 'out' when the water gets too deep. I crossed the Tongan Trench [10,000 metres] with an old Autohelm depth sounder a few years ago that when it was too deep to measure said 'Deep'. I rather liked that 'Deep' but I have never seen it on another depth sounder. Maybe I should look for an old Autohelm depth sounder at a boat jumble.

:D
The East Coast setting for 'deep' would be 'double digits'.
