The hull of a ship is designed to provide buoyancy, which is the upward force that keeps the ship afloat. It also supports the ship's weight and provides structural integrity.

Diesel engines are the most commonly used propulsion system in modern ships due to their efficiency, reliability, and relatively low cost.

The propeller is a rotating device that generates thrust by pushing water backward. This thrust propels the ship forward.

Maximum speed is the highest speed at which a ship is capable of traveling under ideal conditions.

Container ships are designed specifically for transporting large quantities of cargo in standardized containers.

The ballast system is used to adjust the ship's weight distribution and maintain its stability and trim.

Draft is the vertical distance between the waterline and the bottom of the ship's hull.

Cruise ships are designed specifically for transporting passengers on leisure trips.

The bilge system is used to remove water that accumulates in the ship's hull, preventing it from becoming flooded.

Tankers are designed specifically for transporting large quantities of liquid cargoes, such as oil, gas, and chemicals.

Displacement is the total weight of a ship and its contents, including cargo, fuel, passengers, and crew.

Bulk carriers are designed specifically for transporting large quantities of dry bulk cargoes.

The navigation system is used to determine the ship's position and course, and to plan and execute safe voyages.

Ro-Ro ships are designed specifically for transporting vehicles, which are driven on and off the ship using ramps.

Deadweight is the maximum weight that a ship can carry, including cargo, fuel, passengers, and crew.
