Self-righting device for life raft

A life raft comprising:

• a base having a top side and a bottom side;
• one or more buoyancy elements attached to the top side of the base;
• and
• a righting-device attached to the bottom side of the base, the righting-device positioned on the bottom side to cause a shift in a center of gravity when the righting-device is engaged from a first state to a second state, wherein the first state is an unfilled, stowage state and the second state is a filled, deployed state, the righting-device defining a sealable chamber having a valve, the valve operable to allow water to enter the sealable chamber to thus fill the righting-device and transition from the first state to the second state, wherein the shifted center of gravity provides a righting torque to the life raft;
• wherein, when the life raft is subject to an instability event, the righting-device generates a righting moment to automatically return the life raft to an upright position, wherein the righting moment is generated over a full 360° of inclination of the life raft.
