Abstract
A liferaft has a floor (52) surrounded by one or more inflatable tubes (50, 51). Two canopies (54a, 54b) are provided, one (54a) covering one side of the floor (52) and the other (54b) covering the other side of the floor (52). When the liferaft is deployed on water, support means, which may be an inflatable column (63), erect the canopy (54a) that is above the water. The other canopy (54b) is unerected and lies in the water. The system of weights (67) and elastic ropes (66) forms the canopy in the water into stabilizing means in the form of water pockets. Similar means are provided on the deployed canopy (54a) but, when the canopy (54a) is erected, they lie flush with the canopy surface and so do not interfere with the operation of the liferaft.
