How far does it take a cruise liner to stop?

The stopping distance of a cruise liner can vary significantly depending on its size, speed, and the conditions of the water. Generally, a large cruise ship traveling at full speed (about 20-24 knots) may take over a mile to come to a complete stop. Factors such as the ship's weight, momentum, and the effectiveness of its braking systems and propellers can all influence this distance. In emergency situations, cruise liners are designed to reduce speed quickly, but a full stop still requires considerable distance.
