The depth at which a ship sits in the water is known as the draft. Most cruise ships typically have a draft of between 5 metres (16ft 5in ) and 10 metres (32ft 10in). The actual draft depends on the size of the vessel and how much fuel and ballast water is on board. A typical cruise ship draft is 8.5m (25ft 6in).

Nowadays, passengers expect pools to be out in the sunlight and so they must be at the top of ship. This magnifies the risk of throwing the ship off balance in rougher weather when the water starts moving around. That is also why they are often drained and emptied when seas are rough.

Cruise lines drain their swimming pools at night to discourage guests from trying to enter the pool when it is closed. Draining the swimming pools each night also allows the cruise lines to replace the water with clean water and a drained swimming pool is safer if the weather is rough.

MORE DETAILS

The pools are small due to Free Surface Effect. The more room water has to slosh back and forth, the more unstable the ship becomes. The fact that the pools are typically on the highest deck only furthers the need for them to be small.

Do Cruise Ships Dump Sewage? Yes. To get into a few more specifics than above, the U.S. allows cruise ships to dump treated waste into the ocean if they are within three and a half miles from shore. Beyond that point, there are no restrictions for dumping untreated, raw sewage in U.S. ocean waters.

All rooms and locations available to guests are located well above sea level. If you do book a room on a lower deck, it doesn't mean you are at the bottom of the ship below water level. It's just the lowest deck available to guests. Directly under guests last deck is the crew cabins, etc.

Shipboard potable water (drinking, bathing, whirlpools, etc.) either comes from a shoreside water treatment plant or is generated on board from seawater via Reverse Osmosis systems or Evaporators. Swimming pool water is typically seawater.

A whale could not tip over a cruise ship. Although even the largest of blue whales can weigh up to 200 tonnes, the largest cruise ships can weigh up to 220,000 or more. Some cruise ships would carry ten times more freshwater or fuel than the weight of even the largest whales.

When a toilet is flushed on a cruise ship, the sewage travels to the onboard treatment plant. Here the waste is filtered before it enters an aeration chamber. The aeration chamber cleans the waste. It is then sterilized using UV light and released into the ocean when clean enough to do so.
