Ship Stability List Formula
SAILORSTUBE・6 minutes read
The position of the center of gravity is critical for ship stability, impacting the vessel's list movement and transverse inclination. Shifting weight affects the center of gravity, leading to changes in stability and list moment depending on the direction of the movement.
Insights
- Shifting weight on a ship affects its stability by moving the center of gravity, causing list movements and transverse inclination, impacting the vessel's equilibrium significantly.
- The list moment, influenced by the horizontal shift of the center of gravity, can be calculated using a specific formula, showcasing the direct relationship between weight distribution and the ship's stability, highlighting the critical role of balance in maritime operations.

Recent questions
What is the significance of the center of gravity in ship stability?
The center of gravity in ship stability is crucial as it is located at the ship's center line in the transverse direction, with weight acting vertically downward through it. Any shifting of weight on a vessel causes the center of gravity to move, leading to list movement and transverse inclination due to the change in the center of gravity.
How does shifting weight on a vessel impact stability?
Shifting weight on a vessel causes the center of gravity to move, affecting the list moment. This movement can lead to list movement and transverse inclination due to the change in the center of gravity. The horizontal shift of the center of gravity affects the list moment, which can be calculated using the formula W x D / W, impacting the vessel's stability.
What happens when weight is shifted from starboard to port on a ship?
Shifting weight from starboard to port on a ship alters the list moment, with movements towards port creating a list to that side. This change in weight distribution can lead to a list movement and transverse inclination due to the shift in the center of gravity.
How does weight movement impact list moment on a vessel?
Weight movement on a vessel impacts the list moment, with movements towards port creating a list to that side, while movements towards starboard result in a starboard list. The list moment is affected by the horizontal shift of the center of gravity, which can be calculated using the formula W x D / W, influencing the stability of the vessel.
What is the formula to calculate the list moment on a ship?
The list moment on a ship can be calculated using the formula W x D / W, where W represents the weight and D represents the distance. This formula helps determine how the horizontal shift of the center of gravity affects the list moment, impacting the stability of the vessel.
