Ploughing

[Thistle]

From a recent NtM ...



Can anyone shed a bit more light on exactly what they will be doing?

 

[jac]

Laying cables or pipes most likely

 

[johnalison]

Preparing to sow sea grass.

Poor boy dredging? Break up consolidated seabed and let the current wash away the loosened material. Just a guess.
Googling suggests it’s a method of determine seabed suitability for installation of bottom supported structures including pipeline and cable support.

Dredging, I understand that one of HMS needs to return to where it was built.

It happens regularly at the Hardway pontoon when someone's a bit late - or early - back from a sail

Dragging anchor.

Dragging anchor.

Obviously.

They will be testing a number of CQRs, of different sizes.

Doing what is done in Port Edgar and other Forth locations. Dragging a wide blade/bucket across the sea bed and moving mud from place to another. The blade/bucket hangs off two stern davits.

Thank you.

Dragging one of these about the sea bed, it acts like a big broomstick, sweeping the sediment from shallow to deep. Don't go anywhere near a boat engaged in this, very limited manoeuvrability, and it takes a lot of concentration.

Do they have ploughing matches? They are quite popular round here. Tractors and horses. The old boys get quite excited.

Rick Kardy had a Tug at Mayland.(River Blackwater) Due to issues with the conservationists etc. he could not undertake any dredging of the channel to the marina area in the normal manner without special permission. So one of his tricks was to stir the bed with a rake & the ebb would take the mud in suspension out with it.
This is a system undertaken in places like Grimsby dock. ( well they did when I was there last)They stir the bed & drag it along, then open the lock gates & let some water out in a rush & it takes out mud with it
So I assume that the operation mentioned by the Op is a similar system. Stir the bed by raking & letting the current move the silt.
Just a guess so I may be wrong. Others may comment

Entrance to Thornham marina is done most Spring tides.
