Which of the following describes an open life raft?

An open life raft is characterized by its design, which does not include a canopy or any enclosed structure. This absence of a canopy allows for easy deployment and access, making it straightforward for individuals to board quickly in emergency situations. Open life rafts are typically used in scenarios where immediate buoyancy and flotation are necessary, but where the protective features of a canopy may not be required.

Option A refers to a life raft that has an enclosure for protection against the elements, which does not align with the definition of an open life raft. Option B discusses a raft equipped with survival supplies, which can apply to various types of life rafts, not specifically open ones. Option D describes a raft designed for harsh weather conditions; however, an open life raft may not provide the necessary protection that canopies offer in such scenarios. Therefore, the defining feature of an open life raft is the absence of a canopy, making it an essential concept in survival training.
