Hull: The structural body of a ship including shell plating, framing, decks and bulkheads.
Afterbody : That portion of a ship’s hull abaft midships.
Forebody: That portion of a ship’s hull forward midships.
Design Waterline (DWL) or Load Waterline (LWL) : The waterline at which the ship will float when loaded to its designed draught.
Moulded Surface : The inside surface of the skin, or plating, of a ship.
Forward Perpendicular (FP) :
The fore end of the length LWL is the perpendicular to the summer load waterline at the forward side of the stem
After Perpendicular (AP) : The vertical line at the point of intersection of the LWL and the centerline of the rudderstock.
Midships (Ä) : The point midway between the forward and after perpendiculars.
Centerline (CL) : A straight line running from bow to stern, midway between the sides of the ship. All transverse horizontal dimensions are taken from the centerline.
Baseline (BL) : The horizontal line parallel to the design waterline, which cuts the midship section at the lowest point of the ship. The vertical heights are usually measured from the baseline.
Midship Section : The transverse section with the largest
underwater area. The midship section is usually halfway between the AP and the FP.
Sheer
: The height of the deck at side above a line drawn parallel to the base and tangent to the deck line at amidships. The amount of sheer forward is the difference in height between the deck line (at side) amidships and the deck line at the forward end.
The amount of sheer aft is the difference in height between the deck (at side) amidships and the deck at the after end.
Margin Line :
The margin line is a line drawn at least 76 mm below the uppermost surface of the bulkhead deck at side.
Deck Camber : The rise of the deck of the ship in going from the side to the centre. In older ships the camber curve used to be parabolic but in modern ships straight line camber curves are used or there may be no camber at all on decks.
Inner Side :
The inner side is the longitudinal bulkhead which limits the inner hull for ships fitted with double hull.
Superstructure :
A superstructure is a decked structure connected to the freeboard deck, extending from side to side of the ship or with the side plating not beeing inboard of the shell plating more than 0.04*B.
A superstructure may be enclosed or open.
It is enclosed by front,side and aft bulkheads and all front, side and aft openings are fitted with efficient weathertight means of closing.
It is open where it is not enclosed.
Raised Quarter Deck :
A raised quarter deck is a partial superstructure of reduced height |
