A life raft may include a base comprising a first side and a second side, and a self-supporting, collapsible spring canopy. The canopy may include a spring wire frame, a first panel circumscribed by the spring wire frame, and a second panel circumscribed by the spring wire frame. A method of manufacturing a life raft arrangement includes folding the canopy, inserting the canopy into a storage pouch, and coupling the storage pouch to a life raft.

The invention belongs to the technical field of ships, and relates to an aerogel heat preservation ship rescue cabin, which comprises a cabin body. The cabin body and arc-shaped plates are made of aerogel materials. Water pumping devices are symmetrically sleeved outside the cabin body near two sides. A straight pipe is connected between the two water pumping devices. Strip-shaped water outlet holes are formed at front and rear sides of the straight pipe in a penetrating manner. A heat insulation plate is sleeved on the cabin body and hollow, and two ends thereof are communicated with the water outlet holes at front and rear sides of the straight pipe. Multiple drainage holes are formed in the inner wall, opposite to the cabin body, of the heat insulation plate in a penetrating manner. Multiple evaporation holes are formed in the top of the heat insulation plate in a penetrating manner.

A personal life raft includes a rigid compartment, a first flexible arm member in sealed engagement with a first port on a first side of the rigid compartment, a second flexible arm member in sealed engagement with a second port on a second side of the rigid compartment. Each of the first flexible arm member and the second flexible arm member are impervious to water or waterproof such that water does not pass therethrough. The rigid compartment has a body chamber therein having a volume to encompass at least an upper torso of a user of the personal life raft. The rigid compartment displaces sufficient water so that the personal life raft is buoyant while in use by the user.
