Life rafts, or emergency rafts, are inflatable devices used in case of an emergency in a watercraft. They are designed to keep people afloat and protect them from the elements until they can be rescued. Other synonyms for life rafts include rescue rafts, survival rafts, emergency boats, safety boats, inflatable rafts, and lifeboats. These devices have been saving people's lives for decades and continue to be an important safety feature on all types of watercraft. It is important to have a well-maintained life raft on board and to know how to use it in the event of an emergency.
