Which type of life jacket is not recommended for high impact sports?

Type V life jackets are designed for specific activities and often include features that are suitable for conditions where certain performance, such as mobility or comfort, may be prioritized. However, they are not necessarily approved for high-impact sports such as waterskiing, jet skiing, or similar activities, where significant impact with water or sudden falls might occur. Type V jackets are usually intended for activities like kayaking or windsurfing, where a different level of flotation and support is required compared to high-impact sports.

In contrast, Types I, II, and III are generally suited for various water conditions and provide adequate safety for a wider range of activities, including those involving potential impact. Specifically, Type I jackets provide the most buoyancy and are designed to turn an unconscious person face up in the water, making them preferable for rugged waters or emergency situations.

Understanding the specific use and ratings of these life jackets can help ensure safety in various water activities, especially when engaging in high-risk sports. Thus, choosing the correct jacket for the activity at hand is paramount for ensuring proper safety measures are taken.
