The plugin allows you to link your self hosted WordPress Blog with Canalplan AC. It gives you a quick and easy method for linking from your blog to locations within Canalplan. It can also embed Google maps of either locations or whole canals into your blog posts.
There is an advanced feature that allows you to “jump” to Canalplan, plan a route and then pull that route back into your blog where it creates a set of draft blog posts so that you can easily turn your blog into a cruising blog.
Examples of what can be done can be found on the Trips page for Mintball
If you want to try the plugin then its hosted in the standard WordPress Plugin Repository under the name Canalplan. The plugin is installed and activated in the standard way and is fully Network mode compliant.
