Vessel Stability Definitions

Front

What is meant by a vessel being 'heeled'?

Back

A vessel is said to be heeled when she is inclined by an external force such as wind and waves.

Front

What does it mean for a vessel to be 'listed'?

Back

A vessel is said to be listed when she is inclined by forces within the vessel, such as shifting a weight transversely.

Front

What is the center of gravity 'G'?

Back

The center of gravity 'G' is the point through which the force of gravity is considered to act vertically downwards with a force equal to the weight of the body.

Front

What is the center of buoyancy 'B'?

Back

The center of buoyancy 'B' is the point through which the force of buoyancy is considered to act vertically upwards with a force equal to the weight of the water displaced.

Front

What is the significance of point 'K' in a vessel?

Back

Point 'K' is a fixed point at the keel of the vessel from which the center line is produced vertically.

Front

What does 'KB' represent?

Back

'KB' is the height of the center of buoyancy, measured along the center line from the keel (K), in meters.

Front

What does 'KG' represent?

Back

'KG' is the height of the center of gravity, measured along the center line from the keel (K), in meters.

Front

What is the metacenter?

Back

The metacenter is the point on the center line where the vertical line produced upwards from the center of buoyancy (B) intersects it.

Front

What is 'KM'?

Back

'KM' is the height of the metacenter, measured along the center line from the keel (K), in meters.

Front

What does 'BM' represent?

Back

'BM' is the height of the metacenter, measured along the center line from the center of buoyancy, in meters.
