(d) Determinationofthecentreofgravityofashipfordifferentconditions of loading and ballasting. The effect on the position of the centre of gravity of adding, removing, shifting or suspending weights.
(e) Transverse metacentre, metacentric height. Free surface of liquids (without proof) and its effect on stability.
(f) Change of draught and trim due to loading, discharging or shifting weights (MCTC and CF given). Effects of list and trim on stability.
(g) Changes in stability during a voyage, including the effect of a shift of cargo or solid ballast. Grain Regulations.
(h) Load Line; an understanding of those aspects of the conditions of assignment which affect the stability and seaworthiness of a ship.
(i) Stability and Trim when drydocking.
(j) Methods of compensating for discontinuities of strength.
