In addition to the information required in [§ 170.110](/cfr/46/170.110.md), the following information must be included in the stability booklet of a vessel that is required to comply with [§ 173.005](/cfr/46/173.005.md) of this subchapter:

- (a) **Non-counterballasted vessel.** If a vessel is not counterballasted, stability information setting forth hook load limits corresponding to boom radii based on the intact stability criterion in [§ 173.020](/cfr/46/173.020.md) must be provided.
- (b) **Counterballasted vessel.** If a vessel is counterballasted with water, the following information must be provided:
  - (1) **Instructions on the effect of the free surface of the counterballast water.**
  - (2) **Instructions on the amounts of counterballast needed to compensate for hook load heeling moments.**
  - (3) If a vessel has fixed counterballast, a table of draft versus maximum vertical moment of deck cargo and hook load combined.
  - (4) If a vessel has variable counterballast, a table of draft versus maximum vertical moment of deck cargo and hook load combined for each counterballasted condition.
