What type of life jacket is recommended for use in open water?

The recommendation for using a Type I life jacket in open water is primarily due to its design characteristics, which make it the safest and most effective choice in such conditions. Type I jackets are built for maximum buoyancy and are intended for situations where rescue might be delayed. They have a large, high collar designed to flip an unconscious person onto their back, keeping their airway clear of water. This feature is crucial in open water, where conditions may be unpredictable, and the risk of hypothermia or drowning is higher.

In contrast, Type II and Type III life jackets are better suited for calm waters with a higher likelihood of quick rescue, as they offer less buoyancy and may not turn an unconscious person to their back. Type IV jackets are usually throwable devices rather than wearable life jackets and are not designed for continuous wear. Therefore, for those venturing into open water, a Type I life jacket is the optimal choice for enhanced safety and security.
