The Grantham canal round here varies in quality from
Being in a pipe under the road for a big stretch
Looking like a normal canal but with all the locks missing/ damaged
Drained of water and full of weeds
Looking like a normal canal but full of algee and other stagnet strenches
Oh, and most paths/roads cross on the level with nothing more than a pipe
The tow paths are generally navigatable by foot, and from plunger ( I think)
to the trent by bike in all weathers ( if you ignore the a46 Fosseway
crossing which is closed to allow the construction of a dual carridgeway)

Thank you all for your comments.
Dealing with 'disused' was nice and easy - I have deleted disused locks
altogether and changed disused canals to a fainter, dotted line (see just
north of Carnforth near Lancaster). I am not sure I have ever seen a
'disused' canal - does this mean a ditch, or just an overgrown, impassable
I have also prevented locks being shown until you zoom in to zoom level 10.
Updated version now rendering at http://maps.webhop.net/canals, using the
mapnik style http://maps.webhop.net/canals/canal2.xml..
Adding navigable rivers is a good idea, but will take more doing because my
database does not include the 'boat=' tag - I will have to re-import the
whole uk, which takes a few hours.......
Are there any other waterway specific tags that should be included?
What points of interest should a waterways map highlight - I only have locks
at the moment, because I remember these being the interesting part of canal
boating, but I can add other things - especially if anyone would like to
draw an icon for it - otherwise we will end up with another one of my dodgy
