ABSTRACT:
A weak link for securing a life raft painter to a vessel in such a manner that, upon sinking of the vessel, the life raft in its container floats toward the surface to extend the painter its full length. The buoyant force of the raft and container activate a raft inflation mechanism and the increased buoyant force of the inflated raft breaks the weak link and frees the raft from the vessel. In addition, the dual strength weak link can, with a force significantly less than the buoyant force of the inflated raft, be broken manually such that the raft may be freed from the vessel prior to its actual sinking.
