Cruise map a la tube map

I've had a go at creating a map for our summer cruise and thought it would be fun to do it in the style of the London Underground map. As a quick reference I've added approximate time in hours between possible stopping places. A full size version as a pdf is available here on my canalometers page. Or you can follow the link to the Herbie Files on the right of this blog page.
