A large yacht is fitted with an advanced water-maker (reverse osmosis) system supplying most or all of the vessel's fresh water needs for an extended cruise away from port facilities. What operational risk does heavy reliance on this system introduce that a vessel routinely bunkering fresh water in port does not face to the same degree?

A. Water-maker systems are only fitted to yachts under 24 metres and have no relevance to larger vessels

B. A water-maker failure or contamination event (e.g. from operating in polluted coastal water, or membrane fouling) can leave the vessel with a genuine fresh water shortage for crew and guests for the remainder of an extended passage, with limited or no ability to resupply quickly — redundancy, spares, and contingency planning for this system matter more than on a vessel with frequent port calls

C. Water-makers have no meaningful failure modes and can be relied upon without any contingency planning

D. Fresh water shortage has no real operational consequence on a yacht, since guests can simply be advised to use less

A. Zero-speed stabilisers only function while the vessel is making full sea speed

B. Both systems work identically regardless of vessel speed, with no functional difference

C. Underway fin stabilisers rely on forward motion through the water to generate a stabilising force, while zero-speed stabilisers use active fins driven through a different control logic specifically to generate stabilising force with no forward speed — confusing the two systems' capability (e.g. expecting underway-style response from a zero-speed system, or vice versa) can lead to a false sense of security in the wrong condition

D. Stabiliser type has no bearing on guest comfort or vessel motion at any speed

A. Garage systems are only used for tenders under 200kg, where crush risk is negligible

B. The only hazard from a hydraulic garage system is hydraulic fluid leakage, unrelated to mechanical/crush risk

C. The combination of a heavy moving load, confined garage space, hydraulic system failure modes (e.g. uncontrolled descent on a hose failure), and the door/opening mechanism itself creates a crush/entrapment hazard significantly greater than a lighter, simpler davit system, requiring more rigorous isolation and permit-style control during launch/recovery and maintenance

D. Hydraulic tender garage systems carry no meaningfully different hazard profile compared with a simple davit
