Scantling
Scantling is a measurement of prescribed size, dimensions, or cross sectional areas.

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.
