PART 170--STABILITY REQUIREMENTS FOR ALL INSPECTED VESSELS--Table of Contents
 
  Subpart F--Determination of Lightweight Displacement and Centers of 
                                 Gravity
 
Sec. 170.175  Stability test: General.

    (a) Except as provided in paragraphs (c) and (d) of this section and 
in Sec. 170.200, the owner of a vessel must conduct a stability test of 
the vessel and calculate its vertical and longitudinal centers of 
gravity and its lightweight displacement.
    (b) An authorized Coast Guard or ABS representative must be present 
at each stability test conducted under this section.
    (c) The stability test may be dispensed with, or a deadweight survey 
may be substituted for the stability test, if the Coast Guard or the ABS 
has a record of, or is provided with, the approved results of a 
stability test of a sister vessel.
    (d) The stability test of a vessel may be dispensed with if the 
Coast Guard or the ABS determines that an accurate estimate of the 
vessel's lightweight characteristics can be made and that locating the 
precise position of the vessel's vertical center of gravity is not 
necessary to ensure that the vessel has adequate stability in all 
probable loading conditions.
