The Life Raf is an inflatable, high-buoyancy, and portable water-based life-saving and rescue craft, primarily utilized in emergency scenarios such as flood control and disaster relief, maritime rescue, waterborne search and rescue operations, and personnel evacuation.

Based on their intended application, these vessels are categorized into two main types: Professional Rescue Assault Boats (motorized, high-capacity) and Emergency Life Rafts (throwable, self-righting, designed for survival at sea).
