To keep from sinking, the cruise ship has to displace its weight in water before it's submerged. That's a lot easier to do if the cruise ship is constructed in a way so that it's less dense than the water below it. Think of it as the difference between dropping a bowling ball in the water and trying to submerge a beach ball.
Ever since the Costa Concordia disaster, questions have been raised whether modern day cruise ships are being designed more dangerously by increasing their size to pile more and more passengers aboard.. There is no question that cruise ship are getting bigger and bigger. You need look no further than Royal Caribbean’s Genesis class (Oasis of the Seas and Allure of the Seas) which each carry ...

Best Answer: How much of a cruise ship is below the water depends on how much of it is above the water. A cruise ship with fifteen passenger decks will have more of the ship below the water than a cruise ship with only ten passenger decks (the passengers are always above the water line - only the crew sleeps and works below the water line).
As well as a water and light show available to them, passengers can enjoy the ship’s poolside “Movies Under the Stars” screen, and a glass-bottomed walkway that offers views of the sea 128 feet down below. Interior design for the ship was handled by Genoa-based architect Giacomo Mortola and Princess Cruises’ vice president of interior ...
The unique design of the vessel involves not one, but five, “towers”, which are immersed in water – this design is called “Pentamaran.” The top is forked at the rear of the ship deck. “The air cavity” under it improves the hydrodynamic characteristics of the EOSEAS. Double coating vessels provide natural air conditioning.
Large cruise ship hulls are shaped like a squarish shaped letter “U” This design allows water to flow away from the vessel, dissipates drag, and facilitates a smooth ride. Hulls Inside Hulls. In addition to providing passengers with a fluid ride, the hull helps protect a cruise ship so that it doesn’t sink.
The more decks (or air draft) the ship has above water, the deeper the vessel's draft must be. Ship architects must be sure that the ratio of the vessel draft below the waterline and the air draft above the waterline is within acceptable limits. A ship designer doesn't want his or her ship to be so "top-heavy" that it might tip over.
A ship’s draft is the measure of the amount under water. When loaded, ships are around 35 feet deep, depending on the type. If the full height is 80 feet, then it's about 40% under water by its crossection. By weight, a much higher % is under water. A loaded ship with 30,000 tons deadweight and 12,000 light ship weight, weighs 42,000 tons.
A cruise ship is a passenger ship used for pleasure voyages when the voyage itself, the ship's amenities, and sometimes the different destinations along the way (i.e., ports of call), form part of the passengers' experience.Transportation is not the only purpose of cruising, particularly on cruises that return passengers to their originating port (known as "closed-loop cruises").
