Once aboard a liferaft, why is it important to bail out and dry the floor as much as possible, even in cold conditions?

A. Water inside the raft has no meaningful effect on occupants' body temperature once they are out of the sea itself

B. Bailing is purely a comfort measure with no real safety or survival benefit

C. Drying the floor should only be prioritised in warm climates, not cold ones

D. Sitting or lying in water inside the raft dramatically increases heat loss through conduction, even though the air temperature inside the canopy may feel relatively warm — a wet floor undermines much of the thermal protection the raft otherwise provides

A. Cold shock response only affects people with pre-existing heart conditions and is not a general concern

B. Cold shock response is purely psychological with no physical effects on breathing or heart rate

C. Cold shock takes around an hour to develop and is identical to hypothermia

D. Cold shock causes an involuntary gasp reflex, rapid breathing, and a sudden spike in heart rate and blood pressure in the first minute or so of cold water immersion — this is actually a greater immediate drowning risk than hypothermia, which takes much longer to develop, because the gasp reflex can cause water inhalation if the face is submerged at that moment

A. A position used only when removing an immersion suit in calm water

B. A swimming technique designed to maximise speed when swimming towards a liferaft or rescue vessel

C. A position adopted by a lone individual in the water wearing a lifejacket — knees drawn up to the chest, arms crossed and held close to the sides of the body — which reduces the surface area exposed to cold water and protects areas of high heat loss (groin, sides of chest, head), significantly slowing the onset of hypothermia

D. A group huddling technique used only when more than five people are in the water together
