Scenario
You have been supervising the new building of a small commercial vessel. Part of your instructions is to assess the vessel's basic stability and hydrostatic information to produce the appropriate part of the statutory stability booklet for the vessel.
1a. Describe in detail (using appropriate diagrams/drawings) a common accepted method (the inclining experiment) you would use to obtain an accurate assessment of the vessel's initial GM.
1b. Using the following information provided below, calculate the following measurements for this vessel?
Mass Displacement.
Waterplane area.
LCF (longitudinal Centre of Floatation).
BM.
TPC (Tonnes per centimetre Immersion)
Initial KG
Initial GM
The vessel is in salt water.

Waterline length = 50m
Mean draught 1.37m
KB = 0.737m
1c. On the same vessel.
2 x weights A&B (1.8t each) are placed 2.2m each side of the LCB (v/l in equilibrium)
Weight A is moved to the position of weight B giving a pendulum movement of 75mm.
Pendulum length 3m (mounted at the LCB)
If the weight A is moved back to the original position and a new weight of 10t is loaded amidships with a CG of 3m.
What will be the shift of G and the new KG.?
1d. Explain how a KN (SZ) curve is used to determine the vessel's stability data?
Then using the vessel's calculated displacement from 1b and the KN (SZ) curve provided below for this small commercial work boat. (KS is 3.193m)
Draw the vessel's GZ curve of statically stability and state the maximum GZ value?

1e. A different vessel with the following dimensions:-
Waterline length of 100 metres
Displacement of 6300 tonnes.
Mean draught of 6 metres,
Longitudinal metacentre = 104m
Longitudinal Centre of Floatation (LCF) = Amidships
A weight of 60 tonnes is moved from forward to aft over a distance of 50 metres.
Calculate the MCT 1 cm and the new draughts forward and aft for this vessel?
