UK canal and river map created using both public data and user contributions. Points of interest are overlaid on maps of the UK's navigable canals and rivers, and include entries for navigation (locks, bridges, junctions, turning points), boater services (water points, toilet pumpouts, etc.), and commercial services especially relevant to continuous or long-term cruising (e.g. laundry services) The map is generated with help fellow boaters and we welcome your adding missing items to the map. Over 700 items have been added based on user submissions so far, including convenience stores, laundry services, as well as a list of high quality mooring spots, and some hidden gems like private marinas or mooring locations where public access is allowed to waste disposal other boater services. New user contributions are added periodically, and the map will auto update automatically when new points of interest are added Happy boating...
