Inland waterways typically means "no room, no room!" and canals where sailing may be prohibited. It certainly will not be feasible to sail in canals, there's a reason folks use canal boats and barges to live/cruise in those inland waterways.
Take a good look at where you want to go, and what is already being used there. Odds are there's a reason for it. A sailboat makes a terribly impractical way to travel, or place to live, if you can't use the sails to move it.
