Expect to average five to six hours cruising a day. If you have three to four weeks to spare, you can make an extended circular tour, encompassing the wines of Chablis and Sancerre as well as visiting Dijon. These will prevent rope burn as you haul on the lines while passing through the locks, and help you keep hold if your line gets wet. When you arrive at the boatyard you'll be taught how to maneuver the craft and get through locks. Be sure you're confident about the operating procedures before your trainer leaves you to it.
Boats have no brakes, after all.
Hire bikes along with the boat, too - mountain bikes with gears for preference. Not only will these enable the first one awake to cycle into the nearest village to bring back fresh warm croissants, but they'll extend your touring range enormously. Don't worry about lugging the wine you buy back to the boat, either. Most producers will be so impressed you've turned up by bike that they'll deliver your purchases back to your boat. They may even give you a lift back, too.
