How do you determine the weight of the vessel that is supported by the ground when a vessel has run aground?

Correct Answer: Option A — Use the hydrostatic tables and enter with the mean draft before grounding and the mean draft after grounding.

Hydrostatic tables allow mariners to determine grounding reaction weight by entering drafts before and after grounding. The difference in displacement extracted from hydrostatic curves directly quantifies the buoyant force lost to the ground reaction in compliance with stability calculation procedures.
