What is the effect of pumping water out of the ballast tanks?

Pumping water out of ballast tanks reduces the weight and increases the buoyancy of a vessel, allowing it to rise higher in the water. This process enhances the ship's speed and maneuverability, particularly during navigation in shallow waters. However, if done excessively or improperly, it can lead to instability or loss of control. Additionally, changes in ballast can affect the ship's trim and overall seaworthiness.
