A passenger on a cruise ship was injured by a rope thrown while the ship was docking. The passenger was sitting on a lounge chair on the third deck when she was struck by the weighted end of a rope thrown by an employee of Port Everglades, where the boat was docking. These ropes, or heaving lines, were being thrown from the dock to the second deck, and the passenger was injured by a line that was thrown too high. The trial court granted the cruise line’s motion for directed verdict on the ground there was no evidence that the cruise line knew or should have known of the danger. The cruise line contended that it had no notice that this "freak accident" could occur. What is the duty of a cruise ship line to its passengers? Is there liability here? Does it matter that an employee of the port city, not the cruise lines, caused the injury? Should the passenger be able to recover? Why or why not?
