To release the davit cable of a davit launched liferaft, what action is required?

To release the davit cable of a davit-launched liferaft, pulling the release lanyard is the correct action. This mechanism is designed to ensure that the liferaft can be deployed quickly and safely in the event of an emergency. The release lanyard typically operates a release hook or mechanism that detaches the liferaft from the davit system, allowing it to float free and be accessed for use.

Other methods, such as turning a release knob or pushing a release button, may be common in other systems, but they are not standard for releasing a liferaft from a davit. Cutting the cable with a knife is not only impractical but could also pose significant safety risks, as it may damage the liferaft or its deployment system. It's critical to understand the specific mechanisms used in lifeboat launching equipment to ensure proper and safe operation during emergencies.
