A life jacket on your vessel should be sized for which person on board?

A life jacket on your vessel should be sized for the person who will wear it because a proper fit is crucial for ensuring safety and effectiveness in emergency situations. Life jackets that are too large can slip off or fail to keep the wearer afloat effectively, while those that are too small may not provide adequate buoyancy or may be uncomfortable to wear. The regulations mandate that all individuals on a boat should have life jackets that are suitable for their size and weight to ensure they can be properly safeguarded in an emergency. This ensures that each person can get the full benefit of the life jacket's design and capabilities, thus maximizing safety on the water.
