What is the purpose of the long protrusion of the bow on a cruis ship for?

The long protrusion at the bow of a cruise ship, often referred to as the "bulbous bow," serves multiple purposes. Primarily, it helps reduce water resistance, improving the ship's fuel efficiency and speed by creating a more streamlined flow of water around the hull. Additionally, it enhances stability and reduces wave impact, resulting in a smoother ride for passengers.
