Which type of flotation device is required on a boat for each passenger?

The requirement for each passenger on a boat to have a flotation device is specifically fulfilled by a U.S. Coast Guard-approved life jacket. These life jackets are designed to provide adequate buoyancy and ensure the safety of individuals in emergency situations. They are tested and approved to meet specific safety standards set by the Coast Guard, which helps to guarantee their effectiveness.

Other types of flotation devices, such as personal flotation rings, foam buoys, or diving vests, do not meet the same rigorous requirements for safety and buoyancy for use as primary life-saving equipment on a vessel. While these items may have their uses in specific contexts, they are not suitable substitutes for life jackets regarding legal requirements for passenger safety on boats. Thus, having a U.S. Coast Guard-approved life jacket ensures that all passengers are appropriately equipped for safety on the water.
