Two boats are anchored in the harbor, separated by a horizontal distance of 18 m.
The boats bob up and down as waves enter the harbor. When one boat is at its
highest point, the other is at its lowest point and there are no wave crests between
them. Each boat makes exactly 5 complete up-and-down cycles every 10.0 s. The
vertical distance between a boat's highest and lowest position is 2.6 m.
