I saw this about a Captain standing on the bulbous nose of his ship - pictured here:
Not just any ship - the Queen Mary 2! So my very first though was why the life vest? Can the captain of the ship not swim? Is that a desirable quality for a ship captain? After all, if he knows he will be going down with his ship, then he will be more careful, right? It seems a little weak to me, that's all.
