You must be able to put the PFD on in a reasonable amount of time in an emergency.
Readily accessable
Ideally, they should be worn at all times. If you fall overboard, you won't be able to retrieve a PFD (Personal Floatation Device) from a locker on the boat.
PFDs being worn by passengers
any that are sealed in their oringinal plastic bags
Any vessel 16 feet or longer must have at least one Type I, II, or III personal flotation device (PFD) for each person on board. Additionally, vessels must carry a Type IV PFD, which is a throwable device, readily accessible. These regulations ensure the safety of all passengers in case of an emergency.
A disadvantage of a Type IV throwable device PFD (personal flotation device) is that it is not intended to be worn, which means it may not provide immediate buoyancy to a person in distress. In an emergency situation, retrieving and throwing the device can take valuable time, and it may not be readily accessible if the user is in the water. Additionally, it may not be suitable for all situations, such as swift water or rough conditions, where a wearable PFD would offer more reliable safety.
Readily means immediately. It also means agreeably.
A Type IV Personal Flotation Device (PFD) is designed as a throwable device, often resembling a cushion or a ring, intended for use in emergencies. It is typically used to rescue someone in the water rather than being worn. Type IV PFDs are not suitable for non-swimmers or those who are unconscious, and they must be readily accessible on a vessel to be compliant with safety regulations.
i really dont know
The tires on most automobiles are readily accessible if the tires need repair.
According to U.S. Coast Guard regulations, children under the age of 13 must wear a U.S. Coast Guard (USCG) approved personal flotation device (PFD) while on vessels that are underway, unless they are in an enclosed cabin. Additionally, PFDs must be readily accessible for all passengers on board, and certain types of vessels may have specific requirements for PFD use. It is always recommended for all boaters, regardless of age, to wear a PFD for safety.
