Federal Life Jacket Laws in the U.S.
U.S. Coast Guard (USCG) Regulations
The U.S. Coast Guard requires all recreational boats to carry one Coast Guard-approved life jacket for each person aboard. These life jackets must be the right size for the intended user and in serviceable condition. USCG regulations apply to all recreational watercraft in U.S. waters, including paddleboards and kayaks.
Federal Requirement for Children Under 13
Federal law mandates that children under 13 must wear a properly fitted USCG-approved life jacket while aboard any recreational vessel on federally regulated waters. This requirement exists because drowning is a leading cause of death for children, and properly fitted life jackets significantly increase survival chances in water emergencies.
A properly fitted life jacket for children should fit snugly but comfortably. You shouldn’t be able to pull it up over their head when the straps are tightened. Always check the weight rating on the jacket against the child’s current weight.
Exceptions for Enclosed Cabins or Below Deck
Children under 13 don’t need to wear life jackets when they’re below deck or in an enclosed cabin area of a vessel. This exception applies only to fully enclosed spaces on a boat, not partially covered areas.
Even when exceptions apply, life jackets still need to be readily accessible for all passengers—they should be able to be grabbed and put on within seconds if conditions change. Federal regulations represent the minimum safety requirements for boating.
State-Specific Life Jacket Laws
How State Laws May Override Federal Regulations
While federal rules set the baseline for safety, many states have cooked up their own stricter life jacket requirements. These state laws win out when they’re tougher than what the feds require. For example, federal law says kids under 13 need life jackets, but states like California and Nevada bump that up to age 16. Some states also insist on life jackets during certain activities like water skiing or jet skiing, no matter how old you are.
Importance of Checking Local Regulations
Don’t just assume federal rules cover you when you’re cruising between different waterways. State laws can be wildly different – what flies in Florida might get you slapped with a ticket in Washington. Before you hit the water, take a quick minute to look up what’s required where you’re headed. Most state wildlife agencies have handy pocket guides or apps that break down their boating rules. This tiny bit of homework can save you from awkward run-ins with marine patrol and, let’s be real, keep everyone on board a whole lot safer during your adventure.

Examples of State Life Jacket Requirements
Florida: Children under 6 must wear a life jacket on vessels under 26 feet
Florida takes a more targeted approach to life jacket laws, focusing on the youngest boaters. Kids under 6 need to be zipped up in a proper life jacket whenever they’re cruising on smaller boats (under 26 feet). This rule applies whether you’re powering through the Everglades or bobbing along the Gulf Coast. The Sunshine State recognizes that these little mariners face the biggest risks on smaller vessels that can be more easily rocked by waves or sudden movements.
Texas: Children under 13 must wear a life jacket on vessels under 26 feet
The Lone Star State mirrors the federal standard age-wise, requiring life jackets for anyone under 13, but adds its own Texas-sized twist by specifically targeting vessels under 26 feet. This makes perfect sense when you consider that most recreational boating accidents happen on smaller crafts where stability can change in a heartbeat. Texas Parks and Wildlife Department officers actively patrol popular lakes like Travis and Texoma, keeping an eye out for young passengers without proper flotation.
Wisconsin: Children under 12 must wear a life jacket while underway
Up in Wisconsin, they’ve set their own benchmark at age 12 and use the term “underway” as the key trigger for when kids need life jackets. This means if your boat’s moving at all—whether under motor power, sail, or just drifting with the current on one of Wisconsin’s 15,000 lakes—those kiddos need to be jacketed up. The “underway” distinction is important because it recognizes that motion creates additional risk.
Variations in other states
Dig into other states’ rules and you’ll find a patchwork of requirements that reflect local waters and boating cultures. New York requires life jackets for everyone from November through May, acknowledging the deadly combination of cold water and fewer boaters to assist in emergencies. Washington State focuses on vessel type, requiring life jackets on personal watercraft regardless of age. California pushes the age requirement up to 13 and adds mandatory wear for anyone being towed behind a boat, like water skiers and tubers.
Penalties for Non-Compliance
Ignore life jacket laws at your own risk—your wallet’s going to feel it first. Coast Guard citations typically start around $100 but can sail up to a whopping $1,000 depending on severity and repeat offenses. Some states pack an even bigger punch—California can hit you with fines up to $1,500, while Florida’s $90 citation can balloon to over $250 with court costs. These violations also go on your boating record, potentially jacking up your boat insurance premiums for years.
The water patrol isn’t just out there for show. The Coast Guard, state marine patrols, and county sheriff departments regularly conduct “safety checks” on everything from fishing kayaks to luxury yachts. During busy holiday weekends, agencies often set up checkpoints near popular launches—you might find yourself getting boarded before you’ve even cleared the no-wake zone. These officers have complete authority to stop any vessel without needing probable cause. They’re especially vigilant about checking that kids are properly secured in appropriately sized vests, so make sure you’re following both federal and state regulations to keep your cruise smooth sailing.
Safety Recommendations Beyond Legal Requirements
Why All Passengers Should Wear a Life Jacket Regardless of Age
- 86% of drowning victims in recreational boating accidents weren’t wearing life jackets
- Even strong swimmers can get knocked unconscious, become disoriented, or get exhausted when unexpectedly tossed overboard
- Swimming skills won’t help much if you’re suddenly plunged into cold water or knocked out by boat equipment
- Life jackets provide crucial flotation that keeps your head above water even if you’re unconscious
USCG and Boating Safety Organizations’ Recommendations
- The Coast Guard emphasizes: “Life jackets save lives—but only when you wear them”
- The National Safe Boating Council promotes their “Wear It” campaign to encourage constant life jacket use
- BoatUS Foundation recommends everyone wear properly fitted life jackets when on deck or in open areas
- Safety experts suggest wearing life jackets during high-risk situations: rough water, solo boating, and nighttime cruising
- Modern life jackets are designed to be comfortable and allow freedom of movement—no excuses!
Statistics on Boating Accidents and Life Jacket Effectiveness
- Wearing a life jacket reduces drowning risk by approximately 80%
- Nearly 700 boaters died in accidents nationwide in 2023
- Drowning was the cause in over 75% of boating fatalities
- Most drownings occur within minutes of entering the water—too quickly for rescue in many cases
- Like seatbelts in cars, life jackets take seconds to put on but can save your life

Types of U.S. Coast Guard-Approved Life Jackets
Type I, II, III, IV, and V Life Jackets
The Coast Guard categorizes life jackets into five types for different boating scenarios. Type I jackets are bulky offshore vests for rough water and extended rescue times. Type IIs are less bulky “near-shore” vests for calmer waters. Type IIIs are sleek options for controlled environments with quick rescue access. Type IVs are throwable devices like cushions or rings – not wearable jackets. Type Vs are specialty jackets for specific activities like kayaking, often with usage requirements printed on the label.
Choosing the Right Life Jacket for Different Activities
Match your jacket to your activity for maximum safety and comfort. Offshore fishing demands the extra flotation of a Type I, while lake cruising might be better served by a comfortable Type III that allows free movement. Many boaters now prefer inflatable vests that remain slim until needed – a popular choice for adults who resist traditional bulky jackets. Remember that the most effective life jacket isn’t necessarily the most expensive one – it’s the one you’ll actually wear when conditions get rough.
How to Ensure Proper Fit and Use of a Life Jacket
Sizing Guidelines for Children and Adults
Finding the right life jacket means matching it to your body, not just checking a weight range. Adults should measure chest circumference at its widest point and choose a jacket that accommodates this measurement. For children, weight remains the primary sizing factor, but never size up “for room to grow” – a properly fitted jacket is critical for safety.
Adjusting Straps and Ensuring a Secure Fit
The perfect fit comes down to proper adjustment. Tighten all straps starting from the bottom up until the jacket feels snug but allows comfortable breathing. Perform the “tug test” by grabbing the jacket’s shoulders and pulling upward – if it slides above your chin, it’s dangerously loose. For children’s jackets, you shouldn’t be able to fit more than two fingers between their shoulders and the jacket.
Stay Safe and Legal on the Water
Federal rules require USCG-approved life jackets for everyone, with children under 13 needing to wear them on federal waters. Many states have stricter requirements that vary by location, so always check local regulations before boating. Fines for not following these laws range from $100 to $1,500, plus possible increases in insurance costs. The facts are clear: wearing a life jacket reduces drowning risk by 80%, and different types are available for various activities. With this information, you can enjoy your time on the water while keeping everyone safe and complying with all regulations.
FAQs – How Old Do You Have to Be to Not Wear a Life Jacket on a Boat?
Does a 3 month old need a life jacket?
Yes, a 3-month-old baby absolutely needs a life jacket on a boat. Federal law requires all children under 13 to wear Coast Guard-approved life jackets on moving vessels. For infants, you must use a specialized infant life jacket with head support, crotch strap, and grab handle. Never substitute with adult versions or improvised flotation devices.
When should you throw out a life jacket?
You should throw out a life jacket when it shows signs of significant wear and tear such as fading, rips, broken buckles, or mildew that can’t be cleaned. Also discard it if the foam is compressed, waterlogged, or if it fails the “squeeze test” (doesn’t spring back when compressed). Most manufacturers recommend replacement every 5-10 years, even with minimal use.
Who needs a life vest?
Federal law requires all recreational boats to have a Coast Guard-approved life vest for each person onboard. Children under 13 must wear them at all times on moving vessels. Adults should wear them during hazardous conditions, while participating in water sports, when boating alone, or on personal watercraft. The safest practice is for everyone to wear life vests whenever on board, regardless of swimming ability.
