A life jacket is the one piece of gear that has to work when you cannot. Most jackets that fail were the wrong size, worn out, or never adjusted. Here is which type suits your boat, what the label rating means, and how to check the fit before the trip.
Foam jackets are inherently buoyant. No cylinder, no battery, no servicing, and they float you even if you are unconscious. The trade-off is bulk: they get sweaty fast in a Kuwaiti summer and push you onto your back.
For a small boat, a shore trip, or a child, foam is the safest default. Check it by hand each season: stiff panels, cracks, or a jacket that feels suspiciously light means it has lost buoyancy and should go.
An inflatable sits flat until you pull the cord or it fires automatically on contact with water. For an angler standing at the rail for six hours, that comfort is real. The catch: it only works if it is armed and charged.
Never test the automatic inflation while wearing it indoors. Follow the manufacturer label for re-arming, and service a fired or soaked jacket before the next trip.
The label tells you where the jacket is meant to be used and how much buoyancy it provides. Inshore jackets are built for close-to-shore use with fast rescue nearby. Offshore jackets carry more flotation, a collar that turns you face-up, and fittings for a light and whistle. Do not take an inshore jacket on a long run offshore, and never trust a label that has worn blank.
Put the jacket on over the layers you will actually wear on the water, then pull the shoulders upward. If it rides up more than a hand width, it is too big and will slide over your head in a swell. Tighten the chest strap until it is firm but not restricting, then fasten the crotch strap so the jacket cannot lift.
Next, the float test. Step into shallow water with someone watching, and check that your chin stays clear and breathing is easy. If you have to fight to keep your mouth above the surface, the size or the rating is wrong for you. Do this in calm, supervised water. Children need a jacket fitted to their weight, rechecked as they grow.
Replace any jacket with a torn shell, a broken zip, a cracked buckle, or a cylinder past its service life. Foam that has gone flat or hard is finished, and so is a jacket with an unreadable label. A hand-me-down is a gamble unless you know its history.
Follow Coast Guard guidance and local rules on how many jackets you carry and when to wear them, and read the label each season. The B7R app helps before you leave with sea state, wind, and tide times for Shuwaikh and Shuaiba, plus an SOS button if something goes wrong. None of that replaces a jacket that fits.
