You get 24 times as many amps, obviously!

Oops! My apologies, I was convinced it was next year. I really should learn to double check my facts before posting. My only defence is that I've been posting here for years, and must have been contaminated with the alternative truth ...

Well no, but the other end of the pipe was lying on the floor. What stopped the water coming in through the hole in the hull until you (correctly) bunged it up? Add: unless the broken skin fitting remained in place until you started "fixing" it?

? This is a sine of the times ... ? (With apologies to the artist formerly known as Prince!)

Did you miss the 2021 bit? It's just under a year away ... Edit: Ignore this, I was talking bow locks ... See below for actual information from CRT linked by @David Mack

Try it on the short throw pin position on the morse control and the short throw hole on the gearbox lever. You'll probably have to do a lot of screw adjustment, but if it doesn't work on morse long throw and gearbox short throw it's worth a try.

Geek humour from the 1990s - don't worry about it. I'm just concerned that I still have it in my brain nearly 30 years later!

Should we ask how you know this?

How would that help when he smashed the outer part of the skin fitting off? Wouldn't he just end up with the seacock and pipes lying inside the boat and the same hole in the hull?

It's because you were only searching for busbars at a guess. That's a junction box, not a busbar.

Checking, surely? If it always needs bits of metal cleaning off then Bad ThingsTM are happening inside the gearbox!

Oh, I dunno ... it was the BOFH that invented the LART if your memory stretches back as far as usenet and the early days of TheRegister ...

Name and shame him, but certainly don't use him!

Untappd.com ....

My experience of SCADA is in critical national infrastructure - the gas pipelines as it happens. Convincing serious chaps with appropriate moustaches that they should cede 40 years of experience to a couple of cheap transistors and a kid straight out of Uni wasn't really one of my strong points in meetings ... It was pointed out to me quite early on in that project - by a serious chap with an appropriate moustache - that what we software guys considered to be "pump, gas, one of, asset 3" was actually a Rolls Royce jet engine running a huge compressor. If it breaks, Bad ThingsTM happen in a real building with real people stood near it, and he knew where I worked if my code caused said Bad ThingsTM. He was great though. His main job was not-quite-to-destruction testing of said turbines, which was done by him running them above redline until he got a "feeling in his bones" that they were going unstable, then rating them at that level, and only allowing mere mortals (eg serious engineers with less moustache) to run them at 80% of that speed. He famously punched the then chairman of National Grid who some minion once let into a control room and started asking asinine questions just as he was running a turbine up to critical imbalance. I believe the accompanying quote was something like "Get that f***er out of my f***ing control room or he's going to be fed into the intakes!" Once the issue had calmed down, his boss tried to reprimand him, and the order came down from said punched chairman to keep him at all costs ... he'd just saved the company about £50 million with one punch, and the chairman appreciated that far more than he cared about the split lip!

Any of them that have computer controlled weirs / sluices / locks. Seriously. The saving grace for CRT is that many of their operational assets are listed, so they have to be replaced as manually operated structures. There are many more problems or stoppages on the electrical / hydraulic infrastructure than there are on the old fashioned lumps of oak.

The Russians hacked it ... EA are reporting a "software fault" which can range from "system crash: fail safe" (Hah! Irony alert!) to "sensor out of range: resetting to default position." There will have been an alert rather than an alarm, but it might be such a low level it only shows up in diagnostic logging. There may well be a manual override, but it will be in the control box on the sluice, and there obviously won't be people there as the computer system means the staff aren't needed! Yes, I have done extensive work with SCADA systems, and no, I'm not very bitter about it. Why do you ask? I still think putting raw SCADA on the internet was stupid though - the "Russians hacking it" comment was only sarcastic about it being the Russians, not the lack of security in the system.

If it seems to good to be true ... Also having just installed it, it says "This app will deactivate on 01-01-2022.", so a year and a bit hopefully.

Thanks for this Arthur. https://play.google.com/store/apps/details?id=uk.co.rivercanalrescue.waternav&hl=en_GB

Just wait until the owners get their boats back and find they have got a couple of feet of softwood hammered into exhausts and skin fittings. It's the "approved" way of refloating them, and the water level is being held back until all visible holes have been bunged. They deliberately use long pieces of wood so they are blindingly obvious, but I bet there are quite a few owners/renters that don't check their raw water intake or exhaust or shower drain is clear before trying to use it this week. It's a sobering lesson though, especially as it doesn't appear to be the first time this sluice has failed! I agree with @dmr that on a river you can expect quite a bit of level change, but 6 feet from full to dry in less than two hours is way outside what I would tie up for on there. In a drying harbour, sure, but not on most inland waterways.

I read that part as asking the (possible) owner to say what they are to prove it was indeed theirs, not a request for identification!

If you remember the tale, this is the boat that the EA tried to tow off the weir previously, and the tow went wrong while they were doing it and then it sank. I'd be surprised if there's not a very strong round steel pole right where that happened!
