Stability Flashcards
1
Q
What is GZ a measure of ?
A
The righting Lever
2
Q
What does the “Angle of Conflecture” or “point of Inflection” show on a GZ curve?
A
The angle of deck edge immersion
3
Q
What info can you get from a GZ curve?
A
- Range of statically Stability
- Initial GM
- Maximum GZ
- Angle of deck edge immersion
- Angle of vanishing stability
4
Q
Where does an Angle of List GZ curve start ?
A
Below zero in the X axis
5
Q
Why does a vessel with a list have a negative GZ at zero degrees of heel?
A
Because the centre of gravity and buoyancy are not in equilibrium, a capsizing lever is generated, causing the vessel to heel over to the angle of list.
6
Q
What is the purpose of the stability booklet ?
A
To enable the master to calculate the vessels stability under any loading condition
7
Q
Where can you find the KM value for any given draught of the vessel?
A
In the hydrostatic tables in the stability information booklet
8
