The piece of shipboard man overboard equipment that includes a shock absorber is a safety harness. Safety harnesses are designed to ensure the wearer is securely attached and can prevent sudden jolts or falls. The inclusion of a shock absorber is critical, as it helps to reduce the impact on the body when forces are exerted suddenly, such as during a fall or when being recovered.

In a rescue scenario, where safety is paramount, this feature of a harness is essential because it provides additional safety and minimizes the risk of injury to the person being rescued or the rescuer. Other types of equipment, such as a rescue line or flotation ring, serve different purposes and are structured differently without the need for shock absorption. A rescue line is meant for securing and pulling a person back to safety, while flotation rings and life vests primarily focus on providing buoyancy and support in the water, rather than impact protection during a rescue attempt.
