If it was authorised by the Government to operate it was called a privateer. Strictly speaking they were only supposed to attack the enemy's ships in times of war. If it was not authorised then it was a pirate ship.

An aircraft carrier allows airplanes to take off and land on a ship of a navy battle group while it is at sea and far from land. An airplane gives the battle group improved observation at long distance. Airplanes can attack enemy ships without the enemy seeing and firing at your ships.
The ships are fitted with an underwater metal 'beak' , 6 to 12 feet in length , that will puncture an enemy ship below the water line causing it to sink or fill with water to the point that manoeuvrability is compromised thus leaving the ship crippled and unable to effectively engage the enemy ships .

Yes some time they attacks on the ship also. Normally sharks are very violent but when they already have their appetite they don't harm to the ships.
