rawsondsr Posted March 13, 2018 Report Share Posted March 13, 2018 Is there a clear map or source anywhere that shows you where the longer nbs are limited to - a map with lengths in ft for example? Link to comment Share on other sites More sharing options...
Ex Brummie Posted March 13, 2018 Report Share Posted March 13, 2018 Plenty of guides that stipulate the waterways dimensions. Nicholsons have all this information at the start of each waterway chapter. I don't know of any reference work that has complete details all in one list.

Alan de Enfield Posted March 13, 2018 Report Share Posted March 13, 2018 I have a "Stanfords' Inland Cruising Map of England For larger Craft" This has various tables showing (for example) Table A "Locks less than 14 feet" (detailing individual canals) Table B "Locks less than 70 feet long" (detailing individual locks) Then colour coded waterway charts : Blue = Canals & Rivers having locks 14 feet or over wide and 70 feet long or over (See Table A For individual detail) Green = Canals & Rivers having locks less than 70 feet (See table B for individual detail) Red = Canals with locks for craft of 7ft beam only It also has 'Mileage of Through Routes' The 'main chart' is 8 miles to the inch but has 'Mini-Chartlets of 'busy areas' Birmingham (2.5 Miles to the inch) Manchester & Liverpool Area (4 miles to the inch) Goole, Leeds & Huddersfield Area London Area (2 miles to the inch) Link to comment Share on other sites More sharing options...

Peter X Posted March 14, 2018 Report Share Posted March 14, 2018 The devil is in the detail, and no doubt the map Alan mentions will give you a lot of that, but a good rule of thumb is that a full length narrow boat will fit just about everywhere except the canals over the Pennines, the tightest of those being the Calder & Hebble. Lots of boats are around the 70' mark, the longest tend to be old working boats going up to about 71' 6", and most canals in the midlands and south were designed to take those, with that as the minimum lock length. But the locks on those northern canals weren't, so about 58 feet is often referred to as a "go-anywhere" length. Link to comment Share on other sites More sharing options...

Correct it is most of the 'Northerly' canals, and one 'main line' canal that is limited is : Leeds & Liverpool (Leeds to Wigan) 62' 0" Leeds & Liverpool (Rufford Branch) 62' 0" Whilst most of the "under 14 foot width" locks tend to be Midlands-South example : Kennet & Avon (Bath to Newbury) 13' 6" Max beam River Wey 13' 10 1/2" Max beam Link to comment Share on other sites More sharing options...
