Where I live in Worcester is on the River Severn, right by where the Worcester to Birmingham Canal joins the Severn. That narrow boat is from the Alvechurch Boat Company, which is based about 15 miles up the canal. However, the canal isn't the Worcester - Birmingham as the lock operating mechanisms are the wrong type. They do have other bases but I don't know where they are. So a pure guess to start homing in on the location... The Grand Union Canal.
