• and
• a detection system comprising:
• at least two electrical contacts respectively on the first part and the second part so as to establish an electrical connection between them when the life jacket compartment is in the closed state;
• and
• a detection module able to detect a break in the electrical connection between the electrical contacts, and wherein the life jacket further comprising an electrical contact arranged to establish an electrical connection with the electrical contacts on the parts, when the life jacket is inside the internal space in the life jacket compartment and the life jacket compartment is in the closed state.
