It was fun watching that ship stuck in the Suez canal wasn't it? I expect that other canal boaters were like me and Kath shouting "Stand on the back or on the floating side and rock the boat." We could teach 'em a thing or two. I don't suppose they had a shaft or pole long enough to give her a push.
Anyhow I watched an interesting video about how she got stuck and it was interesting to see how the physics of it applies equally to our little boats and that great monster. In a narrow or shallow canal , the water has a job getting out of the way of the boat. We've all been there, or anybody who has been down the Slough Arm or bits of the South Oxford has at any rate. In order to get out of the way of the boat, the water has to speed up and when the bottom or side of the boat is near to the bottom or edge of the canal, that speeding up of the water reduces the pressure (something to do with a Mr Bernoulli if I recall correctly , but as it's been over fifty years since I was an engineering student, I may well not) and the boat get sucked down or into the bank accordingly, thus making matters worse. So if you feel it starting to happen the best thing to do is to slow down and the suction lessens. In the end you'll make better progress.
Boating is often counter intuitive ain't it? Push the tiller right to go left and all that. How often have we seen novice boaters (bless 'em - we were all novices once) come too fast round a corner, see another boat coming and slam on the (practically non- existing) brakes, thus losing all steering. It took me a while to have the confidence to slam on the power to get more steering to avoid a fast approaching obstacle, but it works.
In other news, I came across this somewhat dilapidated gate last Friday:
In need of a bit of TLC, but it won't get it. I don't suppose it's been closed for many a long year. This is what all our lock gates might be like if the canals weren't rescued by volunteers up to their necks in mud in the middle of the last century. (In my mind I hear people saying it looks no worse than some of the locks on the Oxford). Actually this one isn't on a canal, it's at the exit of a fen drain into the Great Ouse. See below, you can see a tupperware boat on the Ouse in the distance).
