Your examiner asks: "What lessons from historical RoRo losses (e.g. the Herald of Free Enterprise capsizing) inform how you, as Master, manage departure readiness today?"

A. That capsizing was substantially attributed to the vessel departing with bow doors open, compounded by an absence of a positive confirmation system and unclear allocation of responsibility for confirming closure before sailing — the enduring lesson is that departure readiness for watertight/weathertight closures must rely on a positive, confirmed reporting chain to the Master (not assumption that "someone" has checked), which is precisely the regulatory and cultural shift (including elements of the ISM Code's safety management system requirements) that followed.

B. That casualty is historical only and has no continuing relevance to modern ISM-compliant RoRo operations or current Master-level practice.

C. The lesson from that casualty relates solely to crew numbers, with no connection to watertight/weathertight closure verification.

D. That casualty led only to changes in passenger lifejacket stowage requirements, with no effect on departure-readiness procedures.

A. The Master retains ultimate responsibility for the vessel's watertight integrity and seaworthiness before departure, even though the practical checks are delegated to officers/crew — the Master must be satisfied (through a reliable reporting/confirmation chain, not just assumption) that all watertight doors required to be closed for sea are in fact closed and confirmed before giving the order to proceed; several real RoRo capsizing/flooding casualties have specifically involved doors left open or unconfirmed at the point of departure, which is why this is treated as a non-delegable command responsibility even though the physical check itself is delegated.

B. Watertight door status before departure is entirely the Chief Officer's responsibility, with no residual Master accountability once delegated.

C. The Master's responsibility ends once a written departure checklist has been signed, regardless of whether the underlying checks were actually carried out.

D. Watertight door checks are a class society surveyor function at each port, not a routine Master/ship's-staff responsibility before every departure.

A. Confirm the vessel's current loaded/operating condition remains within the parameters assumed by the Stockholm Agreement survivability assessment (e.g. any structural modifications, draught/trim limits, freeboard, or watertight door/closure status that the assessment relied on); ensure crew understand and maintain the watertight closures and any cross-flooding arrangements the compliance relies on; and treat Stockholm Agreement compliance as an ongoing operational state to be maintained, not a one-off newbuild certification that, once issued, requires no further attention.

B. Once a vessel is certified Stockholm Agreement compliant at build, no further verification or operational maintenance of that compliance is required for the vessel's service life.

C. Stockholm Agreement compliance is verified solely by the flag state on an annual basis, with no Master-level operational responsibility.

D. The Stockholm Agreement applies only to the vessel's structural design and has no operational/Master-level compliance dimension at all.
