How far underwater is a cruise ship is a question that refers to the distance between a cruise ship's hull and the surface of the waterline. For instance, the Queen Mary 2 has a draft of 30 feet, which means its hull extends 30 feet below the waterline.
Knowing the draft of a cruise ship is important for several reasons. First, it helps determine whether or not a ship can safely navigate a particular waterway. Second, it can affect the ship's stability and handling characteristics. Third, it can provide information about the ship's cargo capacity.
