The Complete Handbook of Life Jacket Accessories

The Real Scope of the Category

A life jacket accessory is any component that is not part of the inherent flotation or primary structural shell of the life jacket itself, but is attached to, integrated with, or worn in conjunction with it. That definition sounds simple, but it covers a surprisingly wide range of hardware and soft goods. Audible signaling devices such as whistles and air horns. Visual signaling devices including rescue lights, strobes, and signal mirrors. Retro-reflective tape that helps search-and-rescue locate a person in the water. Spray hoods that protect the airway from waves and rain. Lifting loops and handles used by rescue teams to haul a person back onto a boat or helicopter. Croch straps and leg straps that stop the jacket from riding up over the head in the water. Inflatable life jacket mechanisms: the CO2 cylinders, frangible pins, auto-inflator sensors, and rearm kits that make an inflatable jacket work. And smaller items, like D-rings, zipper pulls, and lanyards that affect how quickly and reliably the jacket deploys when it needs to.

In practice, the line between accessory and core jacket is not always clear. Many inflatable life jackets come with an integrated harness, and that harness hardware is often considered an accessory even though it is stitched into the jacket during manufacturing. A surface piercing hydrostatic inflator is a component of the jacket system, but when it activates, it pierces a CO2 cylinder that is itself a replaceable, consumable
