When gardening, it is well known that stones grow. This is no different

suggest that sands move and rocks may not be too far below the surface

Yes. Unfortunately, it's no good that way.
They are only around £150 to buy. If you do a lot of drying out, it could be worth mounting the transducer on a boathook as and when required.

Rocks don't move - but sand does! For some years I've enjoyed sneaking through the channel behind Stocker sand in Chichester harbour - rule was that if the sand was covered I could sail through. This Spring just after launch I tried it and ran aground big time!

Back in the Dark ages, when I was in my teens, I remember going to hear a lecture on powder mechanics at Manchester University. One thing I remember is that large particles (such as the rocks) tend to rise when a mixture of fine particles and large ones is agitated. It's because the small particles can easily flow under the large ones when the large particle randomly moves up. So there's a sort of ratchet effect. You can easily verify it in the kitchen, things like raisins will tend to come to the top of a dry mixture.

Despite the title of this thread I cannot think of any disaster those rocks could have caused if they were under a bilge keel,or rudder.

Could they not have displaced the rudder shaft? Or damaged the bearings?
I do not know of your experience or expertise, hence my question.

Boat sat on flat hard sand & rudder sat on a boulder & split in 2 halves

I laid a drying mooring for my first yacht, a Hurley 20. I carefully waded around in deep mud to check all around and all clear. I upgraded to a 25' Tomahawk and used the same mooring with no problems. Several years on and I bought a Southerly 95. First day on the mooring it dried out when I was onboard and I saw a small flat stone a few feet to one side of the rudder. I came back at the next low tide with some tools to shift it. I stood on top and scooped the mud away to determine the size. I gave up when it approached something resembling a sloping billiard table. The highest point was closest to the rudder. That's when we moved our new boat to a nearby marina . All those years and I'd managed to pick a spot for my mooring JUST clear of that single solitary rock.

Same type of situation but I woke up, after drying out, to find my inflatable jammed under my boat due to tide and wind as the dinghy floated before the mother vessel. I now tie it up at the bows overnight to stop this from happening.

Wouldn't do a lot of good if you hit a keel as it would put the keel bolts under a sudden shock and the skeg is only bolted to the hull and is a big lever so there again, not a good thing to do but if the boat had anchored and just settled on the rocks, as the tide went out then I agree but if the boat was run aground to dry out, and was moving at a couple of knots it could have caused damage.

Were you anchored or did you run it aground.

Just anchored, I had previously walked the beach and marked any areas with rocks.

That would have been a disaster for me

That must be where the expression comes from "I am stuck between a rock and a hard place" I think rocks and boats are best kept apart but I have seen bilge keelers, when lifted out of the water resting their keels on some pretty thin pieces of wood.

Rhyl sailor better check on the right entrance for this anchorage.
Getting the wrong entrance into the Skerries lagoon is way worse than a pile of stones by the Ship Inn!

I would not attempt going in there, but is it the entrance to the NE.
