MASTER (LIMITED EUROPEAN) ENDORSEMENT
Ship Construction and Stability ± MSA/SQA
This syllabus is designed to cover only those aspects of ship stability which are of a practical nature and within the control of the master.
(a) Use of stability and hydrostatic data supplied to ships, including
stability date in simpli®ed form. Initial stability and its limitation to small angles of heel. An understanding of the factors affecting the shape of a curve of statical stability and the signi®cance of the area under the curve.
(b) Determinationofthecentreofgravityofashipfordifferentconditions of loading and ballasting. The effect on the position of the centre of gravity of adding, removing, shifting or suspending weights.
(c) Transverse metacentre, metacentric height. Free surface of liquids (without proof) and its effect on stability.
(d) Change of draught and trim due to loading, discharging or shifting weights (MCTC and CF given). Effects of list and trim or stability.
(e) Changes in stability during a voyage, including the effect of a shift of cargo or solid ballast. Grain Regulations.
(f) Load Line; an understanding of those aspects of the conditions of assignment which affect the stability and seaworthiness of a ship.
