List
What is ship stability?
The ability of a ship to float
The ability of a ship to resist rolling and capsizing
The speed of a ship in calm waters
The strength of a ship's hull
What does a positive metacentric height (GM) indicate about a ship's stability?
The ship is unstable
The ship is neutrally stable
The ship is dynamically stable
The ship is statically stable
What is the angle of loll in ship stability?
The angle of list due to wind forces
The angle of heel caused by cargo shifting
The angle at which a ship remains at rest in equilibrium due to asymmetrical flooding
The maximum allowable heel angle for a ship
Which factor can lead to an angle of loll in a ship?
Even distribution of cargo
Symmetrical loading of fuel
Flooding of one side of the ship
Stable metacentric height
How can the angle of loll be corrected?
By increasing the ship's speed
By redistributing ballast or cargo
By reducing the ship's draft
By increasing the ship's metacentric height
Which term describes the lever arm that restores a heeling ship to its upright position?
Metacentric height (GM)
Righting arm
List
Freeboard
What safety precaution helps prevent an angle of loll in a ship?
Monitoring cargo loading
Increasing engine power
Decreasing ballast
Ignoring weather conditions
Why is understanding ship stability crucial for safe maritime operations?
To increase cargo capacity
