What is classified as a throwable saving device?

A throwable saving device is specifically designed to be thrown to a person in water to assist them in staying afloat until they can be rescued. The correct classification for such devices is Type Four, which includes items like life rings, buoyant cushions, or throw bags that provide flotation support. These devices are meant to be easily accessible and quickly deployed in emergencies.

Type One, Type Two, and Type Three personal flotation devices are meant to be worn and provide buoyancy to the user while swimming or in a boat. They are not designed to be thrown, as their purpose is to keep the user afloat during normal activities. Thus, they do not meet the criteria for a throwable saving device, which is why they are not categorized as Type Four. Understanding the differences in these classifications is crucial for vessel safety and emergency preparedness.
