Life Jacket Changes Ahead
In the early 1970s, a new method of categorizing life jackets was introduced by the Coast Guard and Underwriter’s Laboratories, using five “types” and a new, strange name for life jackets: the Personal Flotation Device.
The five types fell into recognizable styles: Type I were for commercial use and had the most buoyancy; Type IIs were inexpensive “yoke” style; Type III were vests that were more comfortable, but had relatively low buoyancy; Type IV were “throwable devices” for man overboard; and Type V were anything that didn’t fit into the previous definitions.
