Le dispositif de flottaison comprend des poignées. Ledit dispositif (70) comprend un compartiment de stockage (74) disposé en relation avec le corps de flottaison (72) pour loger un équipement de sauvetage ou un équipement de sécurité. Le compartiment de stockage (74) selon ce mode de réalisation est en forme de plateau (76). Le plateau (76, 10) est muni d’un couvercle (78) qui est utilisé pour couvrir le plateau et pour maintenir fermement le contenu à l'intérieur. Le couvercle (78) est, de préférence, couplé au plateau (76) par une attache (79). Le plateau (76) est muni d’une bande de matériau souple (104) qui forme une sacoche avec plusieurs poches de différentes tailles, pour stocker une diversité de dispositifs de sécurité comprenant des fusées lumineuses (106, 108), etc. La sacoche peut être enroulée et rangée dans le plateau (76), prête à l'utilisation en cas d'urgence. Selon un mode de réalisation supplémentaire, le corps de flottaison comporte deux parties qui sont reçues de manière coulissante par les poignées de telle sorte que les deux parties peuvent se déplacer entre un état contracté et un état étendu permettant un accès en compartiment de stockage.
