BelgiumBrit,
I suspect that you are basing your whole arguement over inland waterways training on what is in fact a unique place, namely that bridge on the Broads, where hirers are forced to pick up a pilot to navigate it. I suspect that a lot of the skittish moves being made there are actually made by the pilots, so not a true representation.
In general the CANAL system is much less frantic, so scenes like this are rarely seen, even on the busiest canals at peak holiday time. If you have looked at past threads on this forum about hirers and their training (there have been many) you would have seen that although some will complain about poor instruction I think all will agree that SOME instruction is given. Like any situation, some companies are better than others, and instruction can vary from a pre-holiday DVD to an hours instruction on the boat. I am sorry, but to expect a holiday hirer to have a halfday course, for which he will pay extra, on top of an already expensive holiday, is cloud cuckoo land. And to be honest it isn't needed. The ratio of serious accidents to the thousands that holiday is so low to be inconsequential. I think there have been 2 deaths in the last three years, and very few other "reportable incidents" (HSE speak)
I get the impression that you haven't yet experinced the UK canal system, so please don't compare them to Belgium, and come over here and see what it is really like. Only then will your comments have some meaning.
