Скачать или смотреть The underwater gravel vacuum cleaner boat!

This is the dredger boat that operates from Langstone close to our club. She is an awesome vessel and it must be quite difficult navigating to her berth - especially at neaps when the high tide isn't very high! She goes a few miles offshore and sucks up gravel from an ancient riverbed, covered by sea water for millennia. This ancient river must have been huge, as all major rivers in northern Europe like The Thames, The Seine & The Rhine would have been it's tributaries, it was at least a mile wide in places. So next time you crunch over a gravel drive or buy a bag of pea shingle in the south of the UK the chances are that it was once on the bottom of a huge ancient river and brought ashore on this boat!
