What practical step addresses the specific MAIB-identified problem of a lone deckhand going overboard without anyone realising for some time?

A. This risk only applies to vessels with crew of more than 10 and is not relevant to smaller crews

B. Simply working faster reduces this risk sufficiently on its own

C. No practical mitigation exists for this specific problem; it is treated as an unavoidable risk of the industry

D. Avoiding genuinely solitary working wherever practicable, and/or using a man-overboard alarm/personal locator device, with a clear procedure for checking in/being seen at defined intervals during deck operations

A. Falls down an internal companionway stairway

B. A crew member working alone or unsupervised on an open, exposed deck while handling gear, often without a properly worn personal flotation device (PFD), with no one immediately aware they have gone over the side

C. Falls during routine vessel maintenance in port

D. Falls while boarding the vessel from the quay

A. Entanglement is a purely theoretical risk with no real-world basis in fishing vessel incidents

B. This hazard is limited only to trawling vessels and does not apply to pot/static gear vessels

C. Entanglement risk is minimal because modern winches have automatic emergency stops that always activate in time

D. Warps and gear-handling machinery operate under very high tension and can apply enormous, near-instantaneous force, capable of causing traumatic injury, dragging a person overboard, or pulling them into machinery before they can react
