We carry life jackets in a variety of designs to meet the requirements of a wide variety of boating activities. In the video below, Chuck Hawley, West Marine alumnus and recognized expert on boating safety, presents examples and discusses the features and benefits of different life jacket designs. Chuck also discusses USCG Type approvals and gives examples for each. Editor’s Note: In October of 2014, the United States Coast Guard removed references to “Type codes” from regulations on the carriage and labeling of Coast Guard-approved personal flotation devices. As of June 2020, this change affects labeling for USCG Type III flotation devices only. See “Classifying Inflatable PFDs by Coast Guard Types” below.

Who Needs a Life Jacket on a Boat?
The USCG requires all passengers on a boat or other qualifying vessel to have a USCG-approved personal flotation device whenever onboard. Your boat must have at least as many USCG-approved life jackets as there are people onboard. In most states, children under the age of 13 are required to wear a life vest at all times when on a boat.
Some watercraft fall in a gray area. A stand-up paddleboard (SUP) is legally considered a “vessel” by the USCG, and must abide by vessel laws “when used beyond the narrow limits of a swimming, surfing or bathing area.” On the East, West, and Gulf Coasts of the United States, SUPs used outside of the surf zone are required to carry a PFD, a whistle or other sound-producing device, and — if out after dark — a white light to give warning to other vessels. Inland state boating laws vary, so check your local regulations before heading out.
USCG Standards and Life Jacket Types
Personal Flotation Devices (PFDs) are available in inherently buoyant (foam) and inflatable designs. Life jackets were traditionally sorted into “types” based on their performance, but the USCG is transitioning away from the old type designation for some life jackets in favor of icons and Newton ratings that are easier to understand at a glance.
Old type-designated life jackets still meet USCG carry requirements, but new life jackets increasingly show performance factors as icons rather than type numbers. We’ll walk you through both systems so you understand how your life jacket is meant to perform.
Type I
- Required on commercial vessels
- Large, bulky, and uncomfortable for recreational use
- 22 pounds of buoyancy — keeps the wearer high in the water
- Intended to turn most wearers face up, even if unconscious
Type II
- The standard boxy single-strap orange life jacket
- 15.5 pounds of buoyancy — designed to turn most wearers face up
- Not comfortable for extended personal use, but practical to keep aboard for extra passengers to meet USCG carry requirements
Type III
- Up to 15.5 pounds of buoyancy (less for children and youth models)
- Available in a large number of styles for different activities including wakeboarding, kayaking, sailing, and more
- Labeling is gradually being replaced with icon-based labels to make performance and suitability easier to understand
Type IV
- Throwable flotation devices designed to be thrown to a person overboard
- Can double as a crew overboard retrieval device when attached to a line
- All boats 16 feet and longer (except sailboards, racing shells, rowing sculls, racing canoes, and racing kayaks) must carry one
Type V
- Designates a special use device or one that requires special care or knowledge of its specific features
- A catch-all for PFDs that don’t fit other categories but are still USCG-approved
- Often listed as Type V with Type I, II, or III performance to show how the PFD performs when inflated
How to Read the New USCG Life Jacket Icons
The life jacket icons make it easy to tell at a glance how a life jacket performs. There are three categories of icons to understand when choosing the right life jacket.
1. Buoyancy Level, Distance to Shore, and Water Conditions
These icons have three important factors:
- The number: Indicates the buoyancy of the life jacket measured in Newtons. The higher the number, the more buoyant the life jacket.
- The hand, shore, or open water symbol: Indicates how close you will be to rescue when using the life jacket.
- A hand and dock icon indicates rescue is almost immediately available, such as at a beach or pool
- A shoreline icon indicates the life jacket is acceptable for inshore boating where you can still see shore, but rescue may take longer
- An open water icon indicates the life jacket is acceptable for offshore boating where rescue could be hours away
- Water conditions: Straight lines indicate the life jacket is intended for calm, flat water. Jagged wave lines indicate it can be used in rough water.
2. Water Activity Ratings
These icons indicate what the life jacket is not suitable for. From left to right:
- A general attention icon drawing your eye to the other restriction icons
- Not suitable for personal watercraft (Sea-Doo, Waverunner, Jet Ski)
- Not suitable for towed water activities like water skiing or wakeboarding
- Not suitable for riding towable tubes
- Not suitable for whitewater conditions
3. Turning the Wearer in the Water
These icons indicate whether the life jacket is designed to turn most wearers face up in the water. The left icon indicates it will turn the wearer; the right icon indicates it will not. Turning ability is especially important for infant and child life jackets, and in any situation where the wearer might be knocked unconscious when entering the water.
How to Tell if a Life Jacket is USCG Approved
All USCG-approved life jackets are labeled on the inside of the back or front panels. Confirming USCG approval is critically important, especially for infant, child, and youth life jackets. Many swim vests and buoyancy aids are available on the market, but these products are designed for swimming lessons where an instructor is always within reach. For boating and open water swimming, use a USCG-approved life jacket — and for children, one designed to turn the wearer face up in the water.
Classifying Inflatable PFDs by Coast Guard Types
Before Coast Guard-approved inflatables existed, you could determine a PFD’s USCG type by sight. Type IIIs looked like vests or float coats, Type IVs were horseshoes, rings, or cushions. The introduction of inflatable PFDs changed everything. Inflatables are assigned a Coast Guard type just like non-inflatables, but also receive a performance type designation and a specification as to whether they must be worn to count in the vessel’s inventory. You cannot simply call an inflatable a “Type III” and assume it shares characteristics with a foam Type III. All inflatables are for swimmers 16 years or older, and all Type II and III inflatables provide some degree of turning ability and greater buoyancy than comparable foam vests.
- Inflatables with harnesses are Type V by default. Their performance type is generally Type III or Type II. You should be familiar with how to use the harness before wearing one offshore.
- Belt pack inflatables are Type V with Type III performance. They are for competent swimmers only, because they require the wearer to manually don the inflated vest in the water after activation.
- High-buoyancy inflatables (150N / 33 pounds of buoyancy) have a Type III performance rating if manually activated with a ripcord, and a Type II rating if water-activated. Since the bladder and vest are identical except for the inflator, they perform identically once inflated.
- The Coast Guard requires that automatic water-activated inflatables without a single-point arming status indicator must be worn to count in the vessel’s inventory. Inflatables that do include a ready-status indicator (“stowables”) do not have to be worn to count. That said, inflatables are comfortable enough that you should be wearing yours rather than stowing it.
- Inshore Coastal Series inflatables use a 24g cylinder and provide 26 pounds of flotation. They are only legal when worn.
Type IV Throwable Device. Not to be worn.
More About Type V PFDs
Type V PFDs are inflatable devices with special features or that require user interaction to use. PFD Belt Packs are one example — worn deflated at the waist, they must be manually slipped over the head after inflating, making them appropriate for competent swimmers only. Inflatable PFDs with an integrated harness (to which you attach a tether to jacklines) are another example.
- Inflatable PFDs with harnesses are always Type V. When inflated they provide the buoyancy of an offshore SOLAS-grade PFD or Type I foam vest.
- Belt packs are Type V. Base your selection on desired buoyancy level and remember that belt packs are not suitable if there is any risk of going overboard unconscious, since you must manually activate and don the vest while in the water.
- High-buoyancy inflatables with 33 pounds of buoyancy have a Type III performance rating if manually activated, and Type II if water-activated. They perform identically once inflated; the performance rating reflects the method of activation and whether a conscious wearer is required to deploy it.
- Some inflatables are only legal when worn. If you want to stow inflatable PFDs, review the approval label carefully before purchasing.
Many boaters keep spare PFDs stowed for unexpected guests to meet USCG requirements. For stowed spares, we recommend inherently buoyant (foam) models. If you have enough inflatable PFDs aboard for everyone, have each person wear theirs — they are comfortable enough to forget you have one on.
How to Choose the Right Life Jacket for You
The right PFD depends on what kind of boating you do. Here are common activities and the PFDs we recommend for each.
Recreational
Powerboats and sailboats in relatively calm, warm water should be stocked with PFDs that provide comfort and freedom of movement. We recommend a belted or day sailing vest or an inshore inflatable in the Type III category. A Type II PFD can meet requirements for recreational boating but is bulkier and restricts movement. If you spend long days on the water, choose the more comfortable option that won’t chafe.
Water Sports
Wakeboarding, water skiing, towable tubes, and personal watercraft present a risk of repeated water entry at high speed. PFDs for water sports must remain intact and secured to your body through high-speed impact. Belted vests with three or four strong encircling belts work best. Look for vests labeled “watersports” and confirm they can be adjusted to a snug, secure fit. (Editor’s note: The USCG does not allow life jackets to be advertised as providing impact protection, and this cannot be referenced on labels or in marketing.)
Day Sailing
Our Type III Medalist Day Sailing Life Jacket for adults offers a minimum of 15.5 pounds of buoyancy.
Sailing small boats requires PFDs that fit snugly and maximize freedom of movement. The preferred style has a zippered closure and soft, pliable foam. Day sailing vests often feature an articulating design with foam strips in channels that allow the vest to flex and wrap comfortably. Large armholes offer freedom of movement but may allow the vest to ride up when in the water, so a snug fit is essential. If you sail a dinghy or beach catamaran with a trapeze harness, bring the harness when shopping for a new vest. Day sailing vests suit a wide range of boating styles but are not appropriate for high-speed water sports.
Fishing
Fishing vests include built-in pockets for lures, leaders, and tools. Anglers on high-speed bass boats require vests designed to survive high-speed water entry. We offer two distinct types: pocket-style vests for carrying gear, and wide encircling belt styles similar to watersports PFDs that stay secured during high-speed impact.
Offshore Sail
Our All Clear® Offshore Inflatable PFD features automatic or manual inflation and an integrated harness for clipping into jacklines.
Offshore vests provide high buoyancy, freedom of movement, and typically a safety harness for tethering to jacklines. Today’s inflatable offshore life jackets with integrated harnesses provide both functions in one product. Offshore PFDs equipped with Hammar hydrostatic or Halkey Roberts V95000 inflators require complete submersion before inflation — neither will inflate from spray, rain, or humidity. Manual and automatic inflation options are available. Virtually all Offshore Sailing category models provide approximately 35 pounds of buoyancy and a harness compliant with International Sailing Federation (ISAF) standards.
We recommend that offshore powerboaters also carry one or two of these vests. Any time crew must go on a pitching, slippery deck in rough conditions — to ready an anchor or secure a dinghy — a high-buoyancy inflatable with a harness is the right tool.
Offshore Power
Passagemaking requires high-buoyancy life jackets designed for rough water. Even on a trawler with an enclosed pilothouse where the chance of going overboard is low, crew should wear high-buoyancy inflatable PFDs any time they go on deck. If a crew member goes overboard in offshore conditions, rescue time may be long, the water cold, and the sea rough — more buoyancy and a harness become critical.
Paddlesports
Paddlesports PFDs like our Paddle Adventurer jacket feature large arm holes for range of motion and pockets and D-rings for carrying gear.
Canoeists, kayakers, and whitewater rafters need PFDs combining freedom of movement with protection. Many specialized paddlesports PFDs are available for different styles of paddling. Most feature large arm holes and high-cut waists that don’t interfere with a spray skirt. Waist-worn inflatable belt packs are popular among stand-up paddleboarders but are for competent swimmers only, as they require manual donning in the water after activation.
Commercial Vessels
Commercial vessels must carry specific types of life jackets to be legal. We offer a range of Type I life jackets and SOLAS-approved industrial life jackets, but do not recommend them for recreational use. Type I devices are bulky and impractical for recreational activities. If you operate a commercial fishing boat requiring Type I vests, West Marine has you covered.
Fit and Testing
The most commonly skipped step in PFD selection is testing the fit in water before you need it. A life jacket that fits correctly on land may ride up over your face in the water, may not hold you in the correct position, or may be so uncomfortable that you won’t wear it. None of these outcomes are acceptable for a safety device.
Before relying on any life jacket — especially for children — test it in a controlled environment such as a pool or calm, shallow water:
- Put the vest on and enter the water. A properly fitted PFD keeps your chin above water with your head tilted back naturally, not pushed forward by excess buoyancy at the neck.
- If the vest rides up toward your face, tighten all adjustment straps and retest. If it still rides up, the vest is too large or not the right design for your body type.
- For children: hold the vest by the shoulders and lift gently. The child’s chin and ears should not slip through. If they do, the vest is too large.
- For inflatable PFDs: test oral inflation as described in our DIY Check Your Inflatable Life Vest guide.
Other Features to Consider
Hypothermia Protection
Cold water immersion rapidly reduces core body temperature. Even five minutes in 50°F water can impair your ability to climb a ladder, catch a line, or tread water. In addition to protective clothing such as immersion suits, wetsuits, and float coats, a properly fitted Type III vest can delay the onset of hypothermia. High-buoyancy offshore inflatables allow the wearer to assume the Heat Escape Lessening Posture (HELP) — arms crossed over the chest, knees drawn up — which can double survival time in cold water by reducing heat loss.
Maximum Freeboard
A crew member who goes overboard may become unconscious from injury or hypothermia. High-buoyancy inflatable or Type I vests are designed to right an unconscious victim face up in the water and with their extra buoyancy increase freeboard — the distance from the water’s surface to the wearer’s mouth — reducing the risk of drowning while unconscious.
Children
Infants and small children are difficult to keep floating face up and sometimes resist wearing a PFD. There are many well-fitting options providing stability and buoyancy for children of all ages. Look for behind-the-head flotation collars for younger children — these come standard with a grab strap and crotch straps. We strongly recommend testing any child’s life jacket in a pool or calm, shallow water before depending on it on the boat. Review the “Important information about children’s PFDs” card supplied with the device.
Be Safe on the Water
- Always have federally required safety equipment aboard, including USCG-approved life jackets. If you use non-approved devices, back them up with what the law requires.
- If you have older inflatable life jackets (SOSpenders, Crewfit, or West Marine brand) that are in serviceable condition, wear them confidently until their useful life is over (approximately 10 years). If your inventory includes inflatables that must be worn to count, back them up with USCG-approved foam vests so you are never caught short.
- Establish rules on board your boat defining when life jackets are to be worn, and lead by example. Most states require children to always wear a PFD; where no state law exists, federal law requires it for children 13 and younger. The same discipline applied to adults would prevent far more boating deaths than it does today.

Frequently Asked Questions
How many life jackets do I need on my boat?
Federal law requires at least one USCG-approved wearable PFD for every person on board. Boats 16 feet and longer (with limited exceptions) must also carry at least one Type IV throwable device. State law may have additional requirements. Children 13 and younger are required by federal law to wear a PFD at all times when aboard; many states extend this requirement or lower the age threshold.
What is the difference between Type III and Type V inflatable life jackets?
A Type III inflatable is a standard wearable vest. A Type V designates a PFD with special features or that requires specific user interaction — such as a belt pack that must be manually donned in the water after activation, or an inflatable with an integrated safety harness. Type V PFDs often carry a performance designation (Type III or Type II performance) indicating how they perform when inflated. Read the approval label and instructions carefully before purchasing any Type V PFD.
Can I use a swim vest or buoyancy aid instead of a USCG-approved life jacket?
No, not for USCG compliance. Swim vests and buoyancy aids are designed for supervised swimming instruction and do not meet federal carriage requirements for boating. They also typically do not provide enough buoyancy to keep an unconscious person face up in open water. Always use USCG-approved life jackets aboard any vessel.
Do inflatable life jackets need maintenance?
Yes — more so than foam PFDs. Inflatable life jackets require annual inspection of the CO2 cylinder and bobbin (the water-soluble trigger), a bladder leak test, and re-arming with fresh components when due. The bobbin should be replaced every three years regardless of appearance. See our DIY Check Your Inflatable Life Vest guide for the complete inspection procedure.
What does the Newton rating on a life jacket mean?
Newtons are the unit of force used to measure buoyancy under the new USCG icon system. 50N is suitable for calm, near-shore use with immediate rescue available. 70N suits inland and coastal boating. 100N is appropriate for offshore use in moderate conditions. 150N is the offshore and rough water standard, providing the most buoyancy and the best chance of turning an unconscious wearer face up. Higher Newton ratings correspond roughly to the old Type designations: 70–100N ≈ Type III, 100–150N ≈ Type II, 150N+ ≈ Type I.
