LIFE JACKETS
Life jackets for
outfitting large commercial transport ventures in potentially dangerous waters, such as coastal
cruises, offshore passages, and overwater air flights, consisting of either a single air chamber
or a pair of (twin or double) sealed air chambers constructed of coated nylon (sometimes with a
protective outer encasing of heavier, tougher material such as vinyl), joined together, and
buckled with a side release buckle. For use aboard ships they may be constructed of foam.
