Under federal law, you can stop wearing a life jacket at age 13 on most recreational boats. The under-13 rule set by the U.S. Coast Guard is the only federal age threshold for when you must wear a life jacket, and once a child turns 13, no federal regulation requires them to keep one on aboard a typical recreational vessel. Two big caveats: certain activities like riding a personal watercraft or being towed behind a boat require everyone to wear a life jacket regardless of age, and many states set a higher age limit than the federal floor.
The Federal Age 13 Rule
The core regulation is short. No one may operate a recreational vessel underway with a child under 13 aboard unless that child is wearing a Coast Guard-approved life jacket, or is below decks, or is inside an enclosed cabin.1eCFR. 33 CFR 175.15 – Personal Flotation Devices Required On the child’s 13th birthday, the wear requirement lifts. The jacket still has to be aboard for every person on the boat, but a 13-year-old is no longer legally required to have it on.
The jacket has to fit and has to work. Sizing for kids is based on weight, not age:
- Infant: 33 pounds or less
- Child: 33 to 55 pounds
- Youth: 55 to 88 pounds
If you lift the child by the shoulders of the jacket and it rides up past the chin or ears, it’s too big and won’t reliably keep their head above water.
What “Underway” Means for the Rule
The wear requirement only applies when the boat is “underway,” a term with a specific maritime meaning. A vessel is underway whenever it isn’t anchored, tied to shore, or aground. That includes drifting with the engine off. Cut the motor to fish on a lake and the boat is still underway, so a child under 13 still needs the jacket on. The rule lifts once you’ve actually anchored, tied up at a dock, or run aground.
Activities Where Everyone Wears One, No Matter the Age
Turning 13 doesn’t end the wear requirement across the board. Some activities require a Coast Guard-approved life jacket for every person involved, adult or child:
- Personal watercraft. Every operator and passenger on a jet ski, WaveRunner, or Sea-Doo must wear an approved life jacket at all times while the craft is underway.2United States Coast Guard – Boating Safety. Life Jacket Wear / Wearing Your Life Jacket
- Being towed. Anyone being pulled behind a boat while water skiing, wakeboarding, or tubing has to wear an approved life jacket designed for the activity.2United States Coast Guard – Boating Safety. Life Jacket Wear / Wearing Your Life Jacket
Inflatable life jackets aren’t appropriate for either activity. The impact forces involved can keep an inflatable from working properly, so you need an inherently buoyant foam jacket for personal watercraft and towed sports.
States Can Set a Higher Age Than 13
The federal under-13 rule is a floor, not a ceiling. When the Coast Guard adopted the requirement, it explicitly recognized that states with their own existing rules would continue to enforce those instead.3U.S. Power Squadrons. Coast Guard Life Jacket Rule Becomes Effective on December 23 So the age at which you can actually stop wearing a life jacket depends on where you’re boating. Some states cap the requirement at younger ages like 6 or 10; others push it to 12 or higher. A number of states tie the rule to vessel length as well, requiring life jackets for children on smaller boats regardless of age.
Several states also require everyone on board, adults included, to wear a life jacket during colder months when cold-water immersion is most dangerous. Check the rules for the specific state and body of water before you go out. A reservoir in one state can be governed differently from a river that borders another.
Inflatable Jackets Have Their Own Age Floor
There’s a separate age rule that catches families off guard even after a child ages out of the mandatory-wear requirement. Coast Guard-approved inflatable life jackets are authorized only for people at least 16 years old. A 14-year-old on a boat can satisfy the “one life jacket per person” carriage requirement only with a foam jacket, not an inflatable. Swimming ability and body size don’t change this. If you’re outfitting a boat for a group that includes teenagers between 13 and 15, make sure you have enough non-inflatable jackets aboard for them.
Below Decks and Enclosed Cabins
The one federal exemption from the under-13 wear rule on a standard recreational boat is space, not age. A child under 13 doesn’t need to be wearing a life jacket while inside an enclosed cabin or below decks.1eCFR. 33 CFR 175.15 – Personal Flotation Devices Required The moment they step onto an open deck while the boat is underway, the jacket has to go back on. Participants in official regattas, marine parades, and professional exhibitions may also be exempt during the event itself.
What Happens If You Ignore the Rule
A boat operator who fails to comply with life jacket requirements faces a federal civil penalty of up to $1,000 per violation, and the vessel itself can be held liable.4Office of the Law Revision Counsel. 46 USC 4311 – Penalties and Injunctions State fines vary but generally fall in the $25 to $1,000 range depending on the state and whether it’s a repeat offense.
The fine is the smallest part of the exposure. If someone is injured or killed in an incident where the operator failed to ensure proper life jacket use, that failure can be treated as negligence per se in a civil lawsuit, meaning the violation of a safety regulation is itself evidence of fault. Some states escalate serious cases beyond a civil fine to criminal prosecution.
Who Is Responsible on the Boat
The operator carries the primary legal burden. The operator has to make sure every passenger has access to a properly sized, Coast Guard-approved life jacket in good condition, and that any child under 13 who is required to wear one actually has it on. For boats over 16 feet, the operator also has to keep a throwable flotation device immediately available.5USCG Boating. Frequently Asked Questions Canoes and kayaks are exempt from the throwable device requirement regardless of length.6eCFR. 33 CFR 175.17 – Exemptions
Parents and guardians still share responsibility for their own children even when someone else is driving the boat. If you’re putting your kids on a friend’s pontoon for the afternoon, don’t assume the operator has the right sizes on board. Bring jackets you’ve already fitted to your children. The operator gets the ticket. You’re the one who lives with the outcome if something goes wrong.
