The speed limit on London's canals is 4 mph, and everyone knows the canals are slow. But now, even if it is raining outside, you can go on a high speed trip round the 'London Loop' in less than an hour on a souped up narrowboat, with no chance of a speeding ticket thanks to this video by PaulandtheBear. The trip includes the Regents Canal, some great views from the middle of the River Thames at top speed and back to point zero via the Grand Union. They even catch the 'floating in the city' mooring as they zoom past on the fastest narrowboat in London, yet somehow they manage to leave no wake at all. This video is a bit how a 'Waterways View' version of Google's 'Street View' might be. On the other hand at those speeds the 'London Loop' could become the waterways equilivent of CERN.
