for hull saftey, because of the titanic
The main body of a ship is called the hull. The hull runs from the main deck of the vessel all the way to the keel, which is at the center of the vessel where both sides of the hull join under the water. The part of the ship that is built above the hull is called the superstructure.
The hull of a craft is the lower most half, to which the cap is fastened. The hull makes provision for floatation, without which, the vessel would sink.

You are describing a hydrofoil.
This is not a good/valid question as the terms used in it are not compatible I.E. Surface tension has nothing to do with a cavity within the hull (filled or not with water)Perhaps the question was meant to be: Is the displacementof the hull increased when a cavity within the hull of a vessel is filled with water?To this, the answer is yes, as any weight added to the vessel, no matter where it is added (inside a cavity or not) will increase the displacement.The displacement of a vessel such as a ship is a measure of the amount of water that would normally be in the area that the ship now occupies. The weight of this displaced water would be equal to the total weight of the entire ship.
The hull of a yacht is designed to allow the vessel to float and support the rest of the structure. The hull is largely underwater but plays a vital role in the integrity and structure of the ship.
Hull speed is the theoretical limit of a sailcraft's speed. It can be approximated by the following formula: 1.34 * SQRT(LWL), where LWL is the length of the waterline, in feet. As a small vessel approaches its hull speed, the hull begins to climb its own bow wave. The faster the vessel tries to go, the more difficult climbing the bow wave becomes. Eventually, should the hull type permit it, the hull will begin to hydroplane (skimming across the water.
They are marks on the external hull of a vessel showing how deeply the vessel may be loaded. Incorporated in the Merchant Shipping Act of 1876
No - it was a vessel powered by diesel-engines.
distance from the waterline of a floating vessel to the bottom of the keel, less the thickness of the hull.
