What is the most sensitive parameter that affects the accuracy in metacentric?

The most sensitive parameter affecting the accuracy in metacentric height calculations is the center of gravity (CG) location of the vessel. A slight miscalculation in the CG position can significantly impact the stability and metacentric height, leading to potential inaccuracies in predicting the vessel's behavior in waves and during maneuvers. Additionally, the distribution of weight and buoyancy can also influence the metacentric stability, making precise measurement and assessment crucial for accurate stability analysis.
