What is the correct sequence for launching a liferaft manually over the side?

A. Throw the raft container into the water first, then worry about the painter line afterwards if there is time

B. The painter line should be cut immediately after the raft inflates, to allow it to drift freely

C. Check the area below is clear, secure the painter line to a strong point on the vessel before releasing the raft, throw or lower the raft container into the water, then pull the painter line firmly to inflate it — never let go of the painter line until the raft is confirmed inflated and the line is needed to bring the raft alongside

D. Inflate the raft while it is still in its container on deck, then carry the inflated raft to the side

A. The HRU is simply a decorative bracket with no functional release mechanism

B. The HRU only operates if manually armed by an officer before each voyage

C. The HRU automatically releases the liferaft from its cradle if the vessel sinks to a set depth (typically around 4 metres), allowing the raft to float free and inflate even if no one has manually launched it — a critical backup if the crew cannot reach the raft in time

D. The HRU prevents the liferaft from ever being launched manually, for safety reasons

A. An inverted liferaft cannot be righted and must be abandoned in favour of swimming

B. Righting an inverted raft requires specialist tools not normally carried aboard

C. Climb onto the upturned raft, locate the righting strap (usually on the underside, accessible from on top), and pull it while leaning back with full body weight — the gas cylinder is heavier and positioned to help the raft flip the right way when the strap is pulled correctly

D. Push down hard on the centre of the upturned raft to force it to flip over
