The yacht is taking on significant fresh provisions, wine, and equipment ahead of a long charter, to be stowed across multiple storage areas including some above the main deck level. What should the Chief Officer ensure regarding this loading?

A. Stability calculations are only required for cargo ships, not yachts provisioning for charter

B. Stowage location does not matter as long as everything fits

C. Only the galley provisions need to be weighed; other items are negligible

D. That the distribution of weight (particularly anything stowed higher up, such as on a sundeck or upper-deck store) is considered against the vessel's stability margins, that heavy items are stowed as low as practicable where possible, and that the overall loading remains within the approved loading conditions

A. Only the Chief Engineer needs to consider this, never the deck watchkeeper

B. None — stability is fixed regardless of loading

C. Increased displacement generally raises the centre of gravity if weight is added high up, and free surface effects in partially-filled tanks can reduce the effective metacentric height (GM)

D. Additional weight always improves stability regardless of where it is placed

A. This only matters when the vessel is at anchor

B. Negligible — watertight doors below the waterline are rarely closed anyway

C. Only relevant if the vessel carries passengers

D. Significant — a failed watertight closure compromises the subdivision the vessel's damage stability calculations rely on, potentially allowing progressive flooding between compartments in the event of damage
