Mair, Galatea, Patricia.
There are a number of ships that visit the Port of Swansea here in Wales on regular bases, most are involved in the repair of light markers buoys around the coasts of the Bristol Channel and the Celtic Sea.
But some them also specialise in sea surveying and undersea seismic recording, the newer vessels such as the Pharos and Granuila have a all round bridge and are fitted with more powerful cranes.
Lights at sea still remain an essential aids to shipping warning of lower water and sand bars, despite GPS. Trinity house covers both the waters of Britain and Ireland very much like that of the RNLI.

Hovercraft. Part-One.
A British Invention.
Sadly the 'Hoverspeed hovercraft Saunders-Roe SR.N4 Mk3 Mountbatten Class came to a demise with the completion of the Channel Tunnel. This vessel weighed 200 tons, travelled at 70 knots and carried 20,450 litres of fuel. She was powered by four Rolls-Royce Marine Proteus gas turbines and carried 282 passengers and 37 cars.
As a child it was always my ambition to travel on that particular craft to Calais and back, just for the experience.
The Hovercraft began with Sir. Christopher Cockerill in the 1950's and by 1956 aircushon sea vehicles were in commercial service.
Twenty five years ago I got the opportunity to travel to the isle of Wight and then enjoyed travelling on a much smaller craft. It was a bumpy ride across the Solent, but nice to be flying so low to the sea.
That is what the hovercraft does and they are still popular today around the world as they ever were. The RNLI have a few employed in large sandy areas of Britain to rescue those who get stuck in quicksand.

Dredgers.
Sand and Mud.
Modern shipping cannot operate effectively without the deployment of ships that can remove sand and mud bars from river mouths and estuaries. Ships are getting bigger and heavier, they also are some times much larger under the water and now are more likely to scrape their hulls.
The dredging companies are usually under licences to clear and sell sand for commercial uses, where as mud is redeposited to other deep area of water.
Sand and mud flats are created by the under water currents and built up deposits from rain and flooding in rivers. I have filmed quite a number of boats that visit the Port of Swansea and work around the Bristol Channel ports. Arga Bay, Sand Heron/Harrier, Welsh Piper and Arco Dart.
