Consistently operating the vessel in an under ballasted condition can lead to:

Operating a vessel in an under ballasted condition significantly increases the risk of damage and can lead to a reduced lifespan of the ship. Proper ballasting is essential for maintaining the vessel's stability, structural integrity, and safe handling characteristics. When a vessel is under ballasted, it may experience excessive rolling, pitching, and overall instability, which can put undue stress on the hull and other structural components. This stress can result in fatigue cracks, increased wear and tear on the machinery, and potential hull breaches, all of which contribute to a shorter operational life for the ship.

Additionally, vessels that are not adequately ballasted may perform poorly in adverse sea conditions, leading to higher risks during operations. Therefore, while other options might suggest potential benefits of speed or efficiency, the reality is that neglecting proper ballasting can have severe consequences for the vessel's health and longevity.
