Sec. 45.67  Sheer measurement.

    (a) The sheer is measured from the freeboard deck at side to a line 
of reference drawn parallel to the keel through the sheer line at 
amidships;
    (b) In ships designed with a rake of keel or designed to trim by the 
stern, the sheer must be measured in reference to a line drawn through 
the sheer line at amidships parallel to the design load waterline.
    (c) In flush deck ships and in ships with detached superstructures, 
the sheer must be measured at the freeboard deck.
    (d) In ships with a step or break in the topsides, the sheer must be 
measured from the equivalent depth amidships.
    (e) In vessels with a superstructure of standard height that extends 
over the whole length of the freeboard deck, the sheer must be measured 
on the superstructure deck. Where the height of superstructure exceeds 
the standard, the least difference (Z) between the actual and standard 
heights must be added to each end ordinate. Similarly, the intermediate 
ordinates at distance of \1/6\ L and \1/3\ L from each perpendicular 
must be increased by 0.444 Z and 0.111 Z respectively.
