The lever shown in illustration D013SA below is operated when a lifeboat is in which of the following positions?
• Identify what type of mechanism this lever belongs to in a lifeboat launching system (think about hook releasing gear vs. winch brake vs. gripe release). • Consider when it is safe to operate a device that will let the boat separate from the falls. • Review SOLAS/USCG guidance that falls must not be released while the boat is still supported by them.
• If this lever controls the hook release, what would happen to the boat and crew if it were moved at the embarkation deck or while lowering? • At which point in the launching sequence are the falls slack and the boat is already supported by the water? • Would this lever logically be used while the boat is in the davits and secured, or only during the actual launching/release phase?
• Verify whether the illustrated lever is connected to the on‑load/off‑load releasing gear rather than the brake or gripes. • Make sure the option you choose corresponds to the point when the lifeboat is already supported by the sea and not hanging solely on the falls. • Eliminate any choices that would result in the boat being released while still suspended by the falls.
