Lifejacket

"The captain did a safety drill. This covered where the emergency position-indicating radio beacon (EPIRB) was located, how to make a mayday call, and where the fire extinguishers were. A crew member demonstrated how to put on an immersion suit. These survival suits are waterproof full-body garments with a hood and integral three-finger gloves and boots. They are bulky and hard to get on but far more likely to save your life in cold water than a lifejacket. […] But they are also the reasons for the safety campaigns, for the constant and valiant attempts to persuade fishers to wear lifejackets at work, to figure out how to get someone overboard back on the vessel, to carry ladders or gaffers that someone can grab on to."
