What is the function of superstructure in ship?
It is a control tower of the aircrafts, it is the operational center for all the activities on the vessel, and it is also the work station of a majority of the technical staff. Therefore a superstructure serves many purposes. In many ships the superstructure is broader and bigger in size and area.
What is normally the highest structure above the main deck?
The mast nearest the bow in vessels having two or more masts is the foremast. It is usually taller than the foremast, making it normally the highest structure above the main deck.
What’s a ship’s lower deck called?

How superstructure is attached to ship?
A superstructure is a decked structure on the freeboard deck, extending from side to side of the ship or with the side plating not being inboard of the shell plating more than 4% of the breadth (B). A raised quarter-deck is regarded as a superstructure.
What is a fantail on a ship?
The fantail was the rear or aft deck of the ship. Below the fantail are the two powerful 6 foot propellers that propel the ship and the large twin rudders used to steer the SLATER.

Another aspect of superstructure size is its impact on deck space and deck working space. If the superstructure gets too large, the available horizontal deck space for mounting guns, boat cranes and storage, underway replenishment equipment, etc. becomes very limited.
Are there more than one level on a ship?
Vessels often have more than one level both within the hull and in the superstructure above the primary deck, like the floors of a multi-story building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names.
What’s the difference between a superstructure and a quarter deck?
A superstructure is a decked structure on the freeboard deck, extending from side to side of the ship or with the side plating not being inboard of the shell plating more than 4% of the breadth (B). A raised quarter-deck is regarded as a superstructure. (Raised quarter-decks are often associated with smaller ships.
What is the purpose of an upper deck on a ship?
The main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment. The deck serves as the lid to the complex box girder which is the hull. It resists tension, compression, and racking forces.
