Federal law requires one U.S. Coast Guard-approved wearable life jacket for every person on board a recreational boat, and boats 16 feet or longer must also carry one throwable flotation device.1eCFR. 33 CFR 175.15 – Personal Flotation Devices Required So how many life jackets are required on a boat depends on two things: how many people are aboard, and whether the vessel hits that 16-foot mark. Count heads first, measure the hull second, and you have your number.
One Wearable Life Jacket for Every Person Aboard
The baseline is per person, not per boat. No one may use a recreational vessel unless there is at least one wearable, Coast Guard-approved life jacket on board for every person.1eCFR. 33 CFR 175.15 – Personal Flotation Devices Required The rule applies to every kind of recreational vessel: cabin cruisers, bass boats, canoes, kayaks, stand-up paddleboards. There is no carve-out for a quick trip, calm water, or a passenger who swims well.
The jacket also has to be used the way its label says. If the approval label requires the device to be worn to count, as many Type V special-use PFDs do, stowing it in a locker will not satisfy the requirement.1eCFR. 33 CFR 175.15 – Personal Flotation Devices Required Count your passengers before leaving the dock and confirm you have an approved, correctly used jacket for each one.
The Throwable Device for Boats 16 Feet and Longer
Once a recreational boat measures 16 feet or more, add one throwable flotation device to your count.1eCFR. 33 CFR 175.15 – Personal Flotation Devices Required Throwable devices include ring buoys and buoyant cushions built to be tossed to someone who has fallen overboard.2United States Coast Guard. Personal Flotation Devices The throwable is an addition to the wearables, never a substitute. If you have four people in a 20-foot boat, you need four wearable jackets and one throwable, for a total of five devices.
Canoes, kayaks, and paddleboards under 16 feet do not need the throwable. They still need one wearable life jacket per person.
Where the Jackets Have to Be Kept
The count only counts if the equipment is reachable. Every wearable life jacket must be “readily accessible,” meaning grabbable quickly without tools or complicated steps. Throwable devices face a stricter standard: they must be “immediately available,” which in practice means out in the open, not buried under coolers or shut inside a compartment.3eCFR. 33 CFR Part 175 Subpart B – Section 175.19 Stowage A ring buoy jammed behind gear in a storage bin will not pass an inspection, and it will not save a swimmer either.
When the Jackets Must Actually Be Worn
Carrying enough life jackets is one question. Wearing them is a separate rule for certain people and certain activities, and those rules can change how many wearables you effectively need.
Children Under 13
Federal law bars operating a recreational vessel underway with any child under 13 aboard unless the child is wearing an appropriate Coast Guard-approved life jacket. The only exception is when the child is below decks or inside an enclosed cabin.1eCFR. 33 CFR 175.15 – Personal Flotation Devices Required4United States Coast Guard. Child Wear of Personal Flotation Devices – Federal Versus State Requirements The jacket has to be sized for the child. An adult jacket loaned to a child is not compliant, so plan your inventory around who is actually coming along.
To check fit, lift the child by the shoulders of the jacket. If it slides up past the chin or ears, it is too big. Many states impose stricter rules than the federal under-13 requirement, with higher age thresholds or additional wear situations, so check your state before launch.5United States Coast Guard Boating Safety. Life Jacket Wear
Personal Watercraft and Towed Watersports
Everyone aboard a personal watercraft such as a jet ski, WaveRunner, or Sea-Doo must wear a Coast Guard-approved life jacket at all times while underway.5United States Coast Guard Boating Safety. Life Jacket Wear The same applies to anyone being towed: waterskiers, wakeboarders, and tubers. A jacket in a compartment cannot help someone already in the water.
A Jacket That Doesn’t Fit or Work Doesn’t Count
Having the right number on paper is not enough. Every PFD on board must be in serviceable condition and appropriately sized for the person it is meant for.6eCFR. 33 CFR Part 175 Subpart B – Section 175.21 Condition, Size, Fit, and Approval Marking
A foam jacket fails the serviceability test if it has rips or open seams that could let buoyant material escape, if the foam is hardened, waterlogged, or permanently compressed, or if buckles, straps, or stitching are broken or corroded. Inflatable jackets must have a full CO2 cartridge properly armed, working status indicators, intact oral inflation tubes, and a functioning manual pull-cord, and each chamber must hold air.7eCFR. 33 CFR 175.23 – Serviceable Condition
Sizing counts the same way. The jacket must match the wearer’s size as marked on the approval label. A properly sized jacket feels snug without restricting breathing or movement, and it will not ride up past the chin when lifted by the shoulders.6eCFR. 33 CFR Part 175 Subpart B – Section 175.21 Condition, Size, Fit, and Approval Marking A jacket that fails on condition or fit does not count toward your required total.
When Inflatable Jackets Don’t Count Toward Your Total
Inflatable life jackets are lighter and less bulky, but they carry real limits. Inflatables are not approved for anyone under 16 years old, and they are not approved for high-impact uses like waterskiing or riding a personal watercraft. If you outfit the boat with inflatables, you still need traditional foam jackets aboard for children and for anyone doing towed watersports. An inflatable that is not approved for the wearer or activity does not count toward the required per-person total.
Penalties for Coming Up Short
Federal civil penalties for violating recreational boating safety requirements run up to $100 for a first offense, $250 for a second, and $500 for each subsequent offense.8Office of the Law Revision Counsel. 46 USC 4311 – Penalties and Injunctions State fines are often higher and can include license points or mandatory safety courses. The Coast Guard and state marine patrols can board and inspect a recreational vessel at any time.
The safety math is more sobering than the fines. Coast Guard data shows that 87% of recreational boating drowning victims were not wearing a life jacket, and more than 300 drowning deaths in a recent reporting year involved victims without one on.9United States Coast Guard Boating Safety. 2024 Recreational Boating Statistics Count everyone, add a throwable if you’re 16 feet or longer, keep the jackets in good shape and within reach, and put them on the people the law says have to wear them.
