Dredging.

So here is one of the diggers 'dredging' part of Lyme Regis harbour.
The other one was working at the end of Victoria pier(another part of the harbour).
You can see they removed the top layer of sand (piled up in background) so as not to spoil it.
The dredged muck was transported down to the other end of the shingle beach and dumped in the sea.
Took lots of different shots but this one shows what was going on in the Harbour.
Boat looks out of place!
