Lifesaving apparatus for vessels in the form of a buoy releaseably carried by a vessel in a manner so as to float free if the vessel sinks while remaining attached to the vessel by a cable held on a reel on the buoy and having its outer end connected to the vessel. The buoy carries at least one inflatable life raft held in deflated condition in an enclosure which is formed in part by a recess on the buoy body and in part by a cover removably sealed around the recess, the seal being rupturable on inflation of the life raft and the recess being so formed as to allow the life raft to expel itself from the recess during its inflation, the inflated raft then floating on the water while remaining attached to the buoy by its painter. The life raft is arranged to be automatically inflated after the buoy has separated from the vessel by a predetermined distance. The cover is attached to the buoy body in such a way that the top of the cover remains hingedly connected to the body when the life raft starts to leave the recess, so that the life raft is steadied and is unlikely to inflate inverted. A breakable cord connecting the bottom of the raft with the life raft recess also assists in preventing inverted inflation. A drainage hole is provided in the recess to drain off excess moisture from the life raft and from its recess. The buoy when floating with recesses open provides substantial sea-anchor effect.
