District II Quebec City-Les Escoumins - Transports Canada

Candidates
• On the basis of mathematical formulas and
depth under keel:
– calculate squat in a wide shallow
fairway;
– calculate squat in a narrow shallow
fairway;
– assess effects on ship’s behaviour.
• Using technical documentation,
characteristics of the other ships and those
of own ship, anticipate effect of passing
and meeting manoeuvres in fairways.
• On the basis of manoeuvring characteristics
of own ship, assess increased stopping
distance and turning circle as a function
of depth under keel.
• On the basis of ship’s stability tables, data
on cargo, fuel, stores, and other relevant
factors, calculate ship’s centre of gravity so
as to be able to anticipate possibility and
amplitude of list during a sharp turn.
• Using relevant technical documentation,
calculate increase in draught when ship lists
during a rapid change of course.
