Denny and I and TJ and Julie who are off of the boat "ITCHEN" and whom we had met in Mexico did a road trip through Northern Europe this last month. While in Wales we rented this "Day Boat" and took it down a 20 foot wide canal to a pub 4 hours away. We crossed two bridges, one of which was 124 feet high, and went through a half dozed tunnels to get there. The boats move, flat out, at walking speed so it's a nice relaxing day just to meander through the countryside. These boat were small, 30 feet or so, but the houseboat types were up to 60 feet long. Most are 6.5 feet wide X 60 feet long with 4000 miles of canals ahead of you. It could be a great vacation.
