A ring buoy or a life raft that unfurls in water upon being launched. There may be first, second and third ring buoy portions, each having an annular shape of substantially the same inner and outer circumference. The first portion may have a shell containing lightweight material enabling flotation and an extended tube of smoke-generating material, all disposed so that this first portion is weighted to float generally vertically with a smoke-issuing orifice at the top and out of water. The second portion may also have a shell containing lightweight material enabling flotation and may have a flashing light signal, a radar beacon signal, and batteries, all so located that the second portion is weighted to float vertically with the batteries at the bottom and the signals at the top. The third portion may be a normally flat but inflatable tube having an inlet connected to suitable inflating means. Ropes connect the third portion to the first portion and to the second portion, and suitable locking means normally hold the three portions together superposed into one ring buoy assembly. Suitable actuating means cause, upon launching of the buoy, the inflation of the third portion, which then forces the locking means open and separates the three portions for separate flotation, actuates the smoke signal, and actuates the flashing light and the radar beam.

A ring buoy including in combination: a plurality of ring buoy portions, one said portion being inflatable and another portion having signal means thereon, inflation means for said inflatable portion, ropes connecting said portions together, locking means normally holding said portion together superposed into one ring buoy assembly, and actuating means for causing, upon launching of said buoy, (1) said inflation means to inflate said inflatable portion and thereby force said locking means open and to separate said portions for separate flotation, and (2) initiation of said signal means.
