It might be binding on its members, but RSG views are not binding in law. It is not an offence to fail to comply with the RSG edicts.

If the RSG makes binding decisions, it seems odd that the example you provide is merely a recommendation It is the Courts that make decisions on matters of the law.

There is no RCD technical group. The RSG is a trade body providing assistance in interpreting the RCR. No doubt it dispenses good advice, but it does not write the RCR. Despite the long quote, I can't see it addresses the question anyway. Whether a boat is built meeting the ISOs or built meeting the Essential Requirements of the RCR makes no difference to any need for testing, independent or otherwise. It is perfectly possible for a boat to meet the RCR but not all the ISOs; if so there would be no basis of prosecution. It is doubtful that Telemachus meets all the ISOs.

Not so. Where do you consider this requirement lies? Not so. It is a rebuttable presumption. And, anyway, who decides without an inspection that the ISO has been met? This quote is not from the RCR/RCD

Network Rail thanks (in the embedded video) passengers and freight uses for their patience. No mention of the impatient boater.

I went to see the bridge keeper a few years back. Best job in the world, according to him. Anyway, he said the the boats had the right of way. He derived some enjoyment from annoying his railway bosses by not delaying the opening until when they would have liked.

You're doing yourself a disservice. 30 litres for 10 miles is 1.5mpg.

Also in the 1970s, sometimes a crew member would stand on the counterbalance, which sped things up.

Is not the element of your quote supporting your view of bona fide that of Nigel Moore - who was never a member of the judiciary?

You're not quoting the judge for the greater part

If it is 9kw - and you can make the exchange 100% efficient (unlikely) and the rise in temperature is 40c (not much), you'll only get about 2 litres per minute. A typical pump is more like 10 litres per minute, open flow. All assuming I have worked it out correctly.

Indeed. But if there's not enough water leaking past the top gate to hold the bottom gate, you have to question the merits of closing the gate to save water through leakage.

The Worcs & Birmingham was the exception to most canals as boats kept left when meeting another. It's mentioned by Rolt and the Idle Woman. Maybe the "keep right" sign was thought prudent when the change was made?

House painters prefer a well used brush to a new one. Not only is there less bristle loss, but it is said to be better to use. Is it the same for the professional boat painter?
