Does anyone know about barge trips in France

About a year I came accross 2 web sites, one in france on e here in the US , in business for renting such boats.I looked in my favorites on my pC , but I can't find the web address. I am sure if you google , you will them. I think I searched for "Europe cannal trips"
I've never been in such a trip , but I remember reading their brochoure, and the price was very good. I only couldn't figure out how much the gas would cost. A boat uses much more gas then car.
once you find them, ask them to send you a broshure.
Also I noticed that cost of booking with an US company would be cheaper then booking with the one in France, because the price in $ wa sthe same as in EUR.
The ones I looked at were about $900/wek for a 4 person boat.

It's important how much gas those babies take.
According to the brochure I read, for a week. 4-6 person boat you will need just a tank, but I still don't know how big the tank is.
Let me know if you find out.

Based solely on observation, not experience: these trips can be slow. Not that that's a bad thing, but you should know what you are getting.

Canals have many locks, often close together, which generally take one barge at a time. In season there can be lots of traffic. So, you cruise for a few kilometers, wait on line, go through the lock, then repeat.

At least that's how it looked to me when I was bicycling along the Canal Bourgogne two years ago.

This was a revelation, as I had thought renting a barge could be a great way to organize a family trip. Barge rentals are usually for a week, though. It would drive me nuts.

I'm not trying to talk you out of anything, and I think this could be a wonderful experience. Canal life seemed to have many charms. Obviously though you have to be prepared to take it on its own terms.
