You usually divided into bodies whose sides are formed by the outer skin of the hull and deck houses which are delimited by walls, but do not extend to the outer skin. In military ships, arming one of the superstructure. The superstructure includes construction according to the ship design and integrated or placed after the completion of the hull to the ship's deck.

• Roles (movement around the longitudinal axis )
• Stomp ( movement about the transverse axis )
• Yaw (movement around the yaw or vertical axis )

The combination of roll, yaw and pitch also called roll.

In addition, the emissions of noise and vibration will be less if the engine room is not directly under the deck structure.
