What is the main purpose of personal flotation devices (PFDs) in maritime operations?

The primary purpose of personal flotation devices (PFDs) in maritime operations is to ensure safety and survival in water. PFDs are designed to help individuals remain afloat in the water, which significantly reduces the risk of drowning in emergencies, such as capsizing or falling overboard. By providing buoyancy, these devices allow individuals to conserve energy while they wait for rescue or try to reach safety.

While PFDs can also provide some thermal insulation, their main function is to ensure that the wearer stays afloat, making survival the utmost priority in any water-related situation. They are crucial for safeguarding lives during various maritime operations, whether in recreational boating, fishing, or more tactical mission scenarios.
