These electric "mules" are what keep our ship evenly spaced once in the Panama Canal locks. There was only 24" of clearance on either side so it's important that the tension on the cables between the ship and the three mules on each side of our ship are perfect. Otherwise, we'd be leaving paint on the side of the locks. There are three locks on each end of the 50 mile canal. Three steps up and three down. Lake Gatun, in the middle, is man made and took four years to fill. It was a brilliant idea to eliminate a lot of earth removal had a cut been necessary through the entire width of Panama.
