When is the Type III PFD typically worn?

The Type III Personal Flotation Device (PFD) is designed for activities where mobility and comfort are essential, such as boating, fishing, and other water sports. This type of PFD offers sufficient buoyancy to keep the wearer afloat while allowing for a high degree of freedom of movement, making it ideal for use in scenarios where physical activity is involved.

When aboard a vessel, individuals need to maintain agility for tasks such as handling equipment or performing functions critical to the operation of the boat. The Type III PFD provides safety without restricting mobility, which aligns with the requirements for various on-water activities. This makes it a preferable choice over Type I or Type II PFDs, which may provide more buoyancy but could limit movement.

In contrast, the other scenarios do not correctly represent the typical use of a Type III PFD. It is not specifically designed for situations like swimming alone, rescue missions, or emergencies, where different types of PFDs or flotation devices may be more appropriate based on the circumstances and requirements for safety.
