Full Answer

After paddle steamers started to decline in popularity, SS became an acronym for steam ship instead of just screw steamer. Screw steamers were developed after paddle steamers. Paddle steamers had performance issues if the ship was lowered due to added weight. Screw steamers were more effective because the screw-propeller they used performed consistently regardless of depth. As of 2014, ships are identified by an identification code on the side called a hull number.

    How do ship stabilizers work?

    A:

    Stabilizers help to lessen the side-to-side motion, or roll, of a ship. The stabilizers are located on each side of the ship and extend outward in a manner similar to wings. They can be moved up and down to exert the force necessary to prevent the ship from rolling. Stabilizers are common on cruise ships, with one on each side, though larger ships may have two on each side.
