A manual life jacket
, also known as a semi-automatic lifejacket
, is identical in design to a fully automatic lifejacket. With the manual life jacket, however, the swim bladder is inflated by hand
rather than by contact with water.
Manual Life Jackets
A manual life jacket is recommended for all sports where constant contact with water or water spray could result in the unintentional triggering of a fully automatic life jacket. A manual release life jacket is thus perfect for canoeing, kayaking, dinghying, waterskiing, regatta sailing and motorboating.
