Which of the following indicates that water temperatures are above 60 degrees?

The correct answer is the Type 3 life jacket. These jackets are designed for general recreational boating and provide adequate buoyancy while allowing for freedom of movement. They are suitable for use in warmer conditions, where water temperatures are above 60 degrees, offering comfort and mobility without the bulk of thermal protection gear.

A Type 1 life jacket, on the other hand, is typically used in a wider range of conditions, including rougher waters, and provides better protection in case of an emergency but is more bulkier and might not be as comfortable in warmer temperatures. A wetsuit is designed for use in cooler water, as it provides thermal protection by trapping a thin layer of water against the body that the user warms up. The Mustang suit, often a survival suit, is primarily used in very cold conditions and is not suitable for waters above 60 degrees.

Overall, the Type 3 life jacket is specifically appropriate for warm water environments, which makes it the best choice in this context.
