In a flexible blanket (12) comprising a two-dimensional array of shells (14) interconnected by ropes (13) to facilitate flexibility, and which shells may be filled with ballast material (19) to provide a weighted blanket for use underwater, each shell (14) is of a two-part construction comprising upper and lower parts (20) which can be interlocked with one another, e.g. as a snap-fit, to locate the ropes therebetween. |
