speed limit

I don't believe that this is true: "The current speed limit for inland waterways in Great Britain is Four Knots."

it may apply to most small canals, but what about commercial ones?
certainly doesn't apply to all inland waterways.
usually quoted in mph not knots.

Apologies, I read that on a canal boating website, but their source must have been incorrect Grunners 17:07, 26 October 2007 (UTC)[reply]

The further rule from British Waterways is that your craft must not make a breaking wash on the banks, so 4mph is still breaking the speed limit in many narrower and shallower waterways! --feline1 17:10, 26 October 2007 (UTC)[reply]

The speed limit on BW canals (but not necessarily rivers) is 4 mph. This is not the same as 4 knots, which is 4 nautical miles per hour - a nautical mile is 2000 yards, not 1760. As canal boats generally have no means of measuring speed (unless they have a GPS gadget)the 'breaking wave' rule is a useful guide. --Hymers2 (talk) 13:57, 30 January 2008 (UTC)[reply]

Additional inclined planes

Should there not be a reference to the two inclined planes (or trackways) for the Lancaster canal at Preston?

These were at Avenham, (down from Preston to the Ribble), and up the other side at Penwortham, both of which were powered by steam engines, with a further slope at the Summit, which remained horse-powered.

Lead image

Can anyone work out how to get an SVG version of the lead image?©Geni 12:52, 30 July 2011 (UTC)[reply]

An SVG export will be added to the mapping service in the not to distant future at which point it would be easy to create an SVG version, however at present the only export available is raster. In the interim someone could extract the data from OpenStreetMap and create an SVG version of the map but this would probably entail significant coding or manual work.

Ship canals in the UK

I just deleted "the only ship canal in the United Kingdom" from the photo of the Manchester ship canal, since is not true: because of (at least) the Gloucester-Sharpness ship canal (once the largest in the world apparently). I expect the MSC is the *largest* or something in the UK, so perhaps someone can put back in a slightly more restrained claim which is true.Imaginatorium (talk) 10:54, 23 June 2012 (UTC)[reply]

There's also the Crinian and Caledonian canals which were built for shipping. The second paragraph of the lead repeats the "only" claim and needs restraining. Martin of Sheffield (talk) 14:39, 12 February 2018 (UTC)[reply]
