DESCRIZIONE
Represented and described is an inflatable floating body (1) having a closed inner bag (5) and a closed outer bag (3), wherein between the inner bag (5) and the outer bag (3) between a closed volume (17) is formed, with a gas inlet nozzle (11), the inner (15) of the inner bag (5) with the environment (13) of the float (1) is connecting, with a closable test socket (19), extending through the wall (7) of the outer bag (3) extends, with a resilient compressible spacer (21), the between the wall of the inner bag (5) and the wall (7) of the outer bag (3) is arranged and is adapted, at a pressure in the intermediate volume that it (17), of a predetermined minimum difference lower than the pressure outside the outer bag (3) is, compressed, so that an indicator portion (23) of the wall of the inner bag (5) adjacent to the spacer (21) in a first position relative to the wall (7) of the outer bag (3) is held, and at a pressure within the intermediate volume (17), the pressure outside of the outer bag (3) corresponds to, the spacer (21) the indicator portion (23) in a second position relative to the wall spaced (7) of the outer bag (3) holds, and with an indicator device, a display (25) comprises, the is designed such, that on the display (25) a first representation is visible, when the spacer (21) is compressed, and on the display (25) a second representation is visible, when the indicator portion (23) in the second position relative to the wall spaced (7) of the outer bag (3) is.
