Scantling length
Encyclopedia
Scantling
Length is a distance slightly less than the waterline
length of a ship, and generally less than the overall length of a ship.
In the ABS
Rules for Building and Classing Steel Vessels, it is defined as the distance on the summer load line
from the fore side of the stem to the centerline of the rudder stock. Scantling length need not be less than 96%, nor more than 97% of the length of the summer load line.
Most other classification societies
use a similar definition of scantling
length to define the general length of a ship
. The scantling
length is used by classification societies
for all calculations where the waterline
length, overall length, displacement
length, etc is called for. Naval architects wishing to comply with class rules would also use the scantling length.
Scantling
Scantling is a measurement of prescribed size, dimensions, or cross sectional areas. For comparison, see Form Factor: -Shipping:In shipbuilding, the scantling refers to the collective dimensions of the various parts, particularly the framing and structural supports. The word is most often used in...

Waterline
The term "waterline" generally refers to the line where the hull of a ship meets the water surface. It is also the name of a special marking, also known as the national Load Line or Plimsoll Line, to be positioned amidships, that indicates the draft of the ship and the legal limit to which a ship...

Ship
Since the end of the age of sail a ship has been any large buoyant marine vessel. Ships are generally distinguished from boats based on size and cargo or passenger capacity. Ships are used on lakes, seas, and rivers for a variety of activities, such as the transport of people or goods, fishing,...

Displacement (fluid)
In fluid mechanics, displacement occurs when an object is immersed in a fluid, pushing it out of the way and taking its place. The volume of the fluid displaced can then be measured, as in the illustration, and from this the volume of the immersed object can be deduced .An object that sinks...
