A lifejacket is the one piece of life-saving equipment every person on board is given. It has to work for someone who has never worn one, in the dark, after a jump from the deck, and keep an unconscious person’s mouth out of the water. Since 2010 the IMO standard has been tested against a reference lifejacket on real volunteers, and it covers infants, children and people up to 140 kg.
Lifejackets are also one of the commonest small findings in surveys and port state control (PSC) inspections: a missing child lifejacket that is listed on the ship’s Record of Equipment, a light with an expired battery, a stowage box without its symbol. None of these are hard to fix, which is why inspectors treat them as a sign of how well the monthly inspection is done.
