According to regulatory guidelines, what defines survival craft?

The definition of survival craft in the context of regulatory guidelines emphasizes that it is designed to sustain lives until rescue occurs. This means that the primary function of such craft is to provide a safe environment and the necessary provisions to keep individuals alive during an emergency situation at sea until help can arrive.

Survival craft are equipped to handle various conditions, such as exposure to harsh weather and the need for supplies like food, water, and heat. This is crucial in maritime safety because in situations where a vessel is compromised, these crafts can enhance the chances of survival for those aboard.

While other options touch on different aspects of safety and emergency response, they do not capture the comprehensive purpose of survival craft as defined by regulations, which is centered around sustaining life during the critical waiting period until professional rescue efforts can reach those in distress.
