Staying Afloat: Life Jacket Classifications 101

“Don’t forget the life jacket!” you’ve probably shouted (or had a family member shout at you) while boarding your boat. Arguably the most critical water safety device, life vests are essential for every lake homeowner. Federal Law requires all boats to be equipped with one wearable life jacket per passenger. The U.S. Coast Guard categorizes PFDs (Personal Flotation Devices) into five categories based on their function and buoyancy. While some are designed for boating in rough waters, others are made for calmer sports like canoeing. Most every type is available in standard (inherently buoyant), inflatable, and hybrid styles. Before focusing on choosing a life jacket style and cleaning and storing them, it’s important to understand these five basic life jacket classifications. 

Offshore Life Jackets (Type I)

These are the biggest, bulkiest, and most buoyant of the group. This life jacket is suitable for all types of water, but it’s specifically helpful in rough, remote waters where rescue may be slow. Often too intense for recreational use, it’s mandatory for commercial vessels 40+ feet.

Minimum buoyancy: 22lbs (adults) 11lbs (kids)

Advantages: Extreme buoyancy. If an overboard passenger is unconscious, they’ll most certainly stay face-up in the water. 

Disadvantages: Heavier and less comfortable due to excess flotation material. 

Near Shore Vests (Type II)

As the name suggests, Near Shore Vests are designed for use in calm waters that are relatively close to the shore. These would be appropriate for activities like fishing and sailing, where a nearby boat could provide rescue. 

Minimum buoyancy: 15.5lbs (adults) 11lbs (children)

Advantages: More comfortable than type I and turn most wearers face-up in the water if unconscious. Simple, reliable design, and inexpensive.

Disadvantage: Compared to Type I, these life jackets are not as useful in a situation where rescue is unlikely. When unconscious, some wearers may not remain face up. 

Flotation Aids (Type III)

Similar to Type II, Flotation Aids are made for calm, inland waters. The difference is that flotation aids are specifically useful for watersports like fishing, waterskiing, and wakeboarding. Examples of this type of life jacket include float coats, fishing vests, and water sports vests. 

Minimum buoyancy: 15.5lbs (adults) 11lbs (children)

Advantages: They offer a lot of free movement. Comfortable and come in lots of different styles. 

Disadvantage: Won’t turn an unconscious wearer straight up. 

Throwable Devices (Type IV)

When a passenger falls overboard, throw a Type III life jacket their way. A device that is designed to be held rather than worn; this category includes ring buoys, horseshoe buoys, and floating cushions. Like types II and III, they are designed for calm waters with a good chance of quick rescue. 

Minimum buoyancy: 16.5 lbs for a ring buoy or 18 lbs for boat cushion 

Advantage: Can easily be thrown from a boat to the overboard passenger. They’re also easy to carry aboard a boat — just be sure not to use as a cushion as it degrades the foam. 

Disadvantage: Not designed for children and non-swimmers. They also do not count as a “wearable vest” per federal regulations, and can only be used as backup support. 

Special Use Devices (Type V)

This final life jacket category includes vests for unique activities like sailing, kayaking, windsurfing, water skiing, white water rafting. Think of specialized uniforms like deck suits, work vests, and insulated jackets for cold waters.  

Minimum buoyancy: 15.5lbs to 22lbs

Advantages: They’re uniquely tailored to your activity. 

Disadvantages: They are not generalizable for all recreational use. They also require extra effort, as they must be worn when underway. You can’t just have them on board. 

Grab the jacket that’s right for you, and stay safe on the water! 

Choosing the Right Life Jacket

One half of fatalities from recreational boating happen on the calm water, often even close to the shore.

In most cases life jackets are on board, but either go unworn or are not worn properly.

Activities that calls for life jackets are:

  • collection of life jacketsCruising
  • Paddling
  • Angling
  • Waterskiing
  • Racing
  • Swimming
  • Being Next to the Water

All people, from adult males to young children and pets, should wear the life jackets. Here are ways to ensure you have the right one.

Checking the Size

The size and weight information for each jacket can be found on the label. This will tell the range of weight the floatation device can support as well as the recommend height range of users.

Make sure that the jacket is fastened in the right fashion.

To do this, hold your arms over your head. If the tops of the arm openings can be pulled up past your chin, then the jacket is too big. It needs to be able to hold your head out of the water.

Auto Inflatable Life Jackets

This type of life jacket will automatically inflate upon immersion or from manual activation.

If a person wearing an inflatable jacket is in an accident and rendered unconscious, the device will turn the wearer face upwards.

These life jackets are not meant to be worn by children 16 years of age and younger. Additionally, this floatation device is not suitable for use in water sports.

Manual Inflatable Life Jackets

These jackets inflate only when wearers manually trigger the inflation device.

Manually inflatable jackets are cool and comfortable to wear since they are not bulky like most other life jackets.

This kind of jacket will also turn the wearer face up should they be rendered unconscious; however, it has to be inflated before their accident.

These do require some regular maintenance to insure inflation devices and pull cords are in working order and that there are no holes in the jacket itself.  Jackets of this kind should not be worn by children 16 or younger.

They are not recommended for water sports either.

Belt Pack Inflatable

This life preserver will also inflate automatically if it is submerged or it can be manually inflated.

Very easy to wear, this device wraps around and is secured to the wearer’s waist.

It should be placed over the head after it has been inflated and also requires regular maintenance.

Belt packs are not meant for water sports or children 16 and younger.

Vest Life Jackets

This is the most seen life jacket. They are typically orange.

The vest can turn an unconscious person face up and requires very little maintenance.

This is a great life jacket for those who do not know how to swim. It is also versatile as it is great for using as a flotation device. It is normally less bulky than other off-shore vests.

Children’s Hybrid Inflatable

These types of life jackets offer automatic inflation, but it can also be inflated manually.

These do require regular maintenance, and will turn an unconscious person upward like others mention previously.

It is not meant to wear during water sports.

Children’s Life Jacket

These types of life jackets are designed for possible immersion.

It may not turn a person face up, but requires little maintenance.

Most types of life jackets typically includes safety features for your child.
