Not only do they seem to have a detailed route planning tool, there is also an extensive gallery of British canal pictures, and (for the boat-builders/designers among us) a very neat, interactive narrowboat layout tool.
Narrowboats are great for an amateur doing interior design, since they are much more "house-like" than many boats. A constant width, fairly square cross section, and extensible to various lenghts, you have a lot of lee-way on interior layout. This tool let’s you drag and drop various common interior features together into your plan, then download the PDF of your masterpiece.
Welcome to Narrowboats.org a site that is dedicated to the canals and narrow boats in the United Kingdom. This is a new site offering access to a huge database of canal related information.
The canal planner alone uses more than 10,000 canal points digitised from the Google maps of our canal network; these are used to produce a personalized downloadable PDF document of your planned canal journey.
