Stability booklet

A stability booklet is the class- and flag-approved document giving the master the information to keep the ship within its stability limits in service. It contains the lightship particulars from the inclining experiment, the hydrostatic data and cross-curves, a set of standard loading conditions (full and partial cargo, ballast, arrival and departure) each checked against the IMO 2008 IS Code, free-surface and grain-heel data where relevant, and instructions for assessing any other condition. SOLAS Chapter II-1 Regulation 5-1 requires it aboard in a language the officers understand. The trim and stability booklet is the same document with the trim and loading information emphasized; the two terms are used interchangeably aboard many ships.
