I like that sort of stuff.
Anybody who has done a reasonable amount of canalling with a narrow boat will recognise the "squat" phenomenon - I had always put it down to the prop throwing water out from under the stern but clearly there's a bit more to it, if it happens with a brick that has no propeller! I should have known Bernoulli's principle would have something to do with it.
I wouldn't say it qualifies me as a Suez pilot, but about 25 years ago we took a lovely hire boat, probably about 60', called Poppy up the shallow Caldon canal from Stoke. Built by the renowned Les Allen it had a slightly deeper draft than is typical for such boats and even at moderate speed we had a bit of trouble running aground at the stern or removing ropes, plastic fertiliser sacks etc. from the prop despite keeping up the middle in the deepest water. Reducing speed to less than half walking pace proved to be the answer.
