Life Jacket PFD – 275N+ Review and Comparison

You can’t cross the sea merely by staring at the water…

Life Jacket Review in Australia

There is a purpose to your actions. You act decisively and without fear. You are also a planner who will mitigate any possible danger. Life jackets for your crew is one of those things you refuse to compromise on; you are, after all, their skipper…

Let’s talk about life jackets or PFDs…

Before delving into the nitty-gritty of life jackets or Personal Floating Devices (PFDs) let me say this; get a device you are willing to wear! It is the same with protective gear on a motorbike. If you go for the bulky cheaper gear based on a “that will cover any event” attitude, you will probably not wear the device on the day you need it most; it will be stowed in your locker whilst you are facedown floating in the water.

Okay, let’s move on from that somewhat sobering thought. In terms of terminology, a PFD is an umbrella term that denotes anything that will keep you afloat. This can include a life jacket but may also include other devices such as floating rings or a pool noodle for that matter.

When we are talking about life jackets or PFDs, we are talking about devices that are important. Naturally, “important” is rather subjective so the legislators commissioned ratings or standards of PFDs within numerous jurisdictions. This includes international legislation down to State level. Hell, the ACT even has legislation covering life jackets! As a general rule, the more localised standards trump the wider standards so make sure what your local State or Territory has to say about the use of PFDs. Saying that, often local jurisdictions adopt standards that are internationally recognised; but not always and almost always not 100%.

Here is a list of “some” of the standards:

International Standards – ISO

International Standards – ISO

ISO (International Organization for Standardization) is a global standards organisations and has created the international standards for life jackets. Where a jacket is compliant with ISO standards it will be marked with “ISO” on the vest and the standard type. An ISO-compliant jacket does not make the jacket compliant at your local level unless the local jurisdiction refers to ISO as such.

European Standards (EN) – CE

European Standards (EN) – CE

The CE standard is defined by the European Standards (EN) and is accepted by the European Union as well as by the European Free Trade Association. CE compliance is recognised by 30+ member European nations. If the vest is compliant it will be marked with “CE” on the vest and the standard type. A CE compliant jacket does not make the vest compliant at your local level unless the local jurisdiction refers to CE as such.

ISO & CE Types

By a small miracle, both ISO and CE types are identical in relation to their buoyancy and most features.


50N – Buoyancy Aid

Intended for competent swimmers in sheltered water were help is nearby. They only provide support to conscious individuals who can help themselves.  50N buoyancy aids are a flotation aid only. 50N buoyancy aids offer 50 Newtons of flotation.

EN 395 EN ISO12402-4 100N LIFE JACKETS

100N – Life Jacket

Intended for swimmers and non-swimmers in calm inshore waters. 100N life jackets give fair assurance of safety from drowning in relatively calm waters. Not guaranteed to self-right an unconscious person and should not be expected to protect the airway of an unconscious person in rough water. 100N life jackets offer 100 Newtons of flotation.

EN 396 EN ISO 12402-3 150N LIFE JACKETS

150N – Life Jacket

For swimmers and non-swimmers for usage in all but the most severe conditions. 150N life jackets give satisfactory assurance of safety to people not fully capable of helping themselves. May not instantly self-right an unconscious person wearing heavy waterproof clothing like foulies. 150N life jackets offer 50 Newtons of flotation.

EN 399 EN ISO 12402-2 275N LIFE JACKETS

275N – Life Jacket

For swimmers and non-swimmers. A high-performance life jacket for offshore and extreme conditions when maximum buoyancy is needed or where heavy clothing or tools are worn. 275N life jackets give the best assurance of safely from drowning to people who are not capable of helping themselves. 275N life jackets cannot be guaranteed to self-right an unconscious person wearing heavy clothing or tools although in most cases this will be expected. 275N life jackets offer 275 Newtons of flotation.

USCG Approved US Standards

It would be way too simple to leave it at that. It is obvious we need more standards. The yanks can oblige with the United States Coast Guard (USCG) Standards. Let’s have a further look at these USCG standards.


A TYPE I PFD, also referred to as an off-shore life jacket, provides maximum buoyancy. It is efficient in all (open) waters, rough, or remote waters where rescue may not be instantaneous. It is devised to self-right most unconscious persons. TYPE I comes in two sizes: Adult size provides at least 22 pounds of buoyancy as well as a child size which must provide at least 11 pounds of buoyancy.



A TYPE II PFD, NEAR-SHORE BUOYANT VEST is meant for calm, inland water or where there is a good chance of a speedy rescue. Type II will self-right some unconscious persons but is not guaranteed to do so. The self-righting is not as reliable as a TYPE I. An adult size must provide a minimum of 15.5 pounds buoyancy, a medium child size must provide as least 11 pounds. Infant and small child sizes each must provide at least 7 pounds buoyancy.



A TYPE III PFD, also known as floating aid, is great for calm, inland water, and where there is a good chance of rapid rescue. A type III PFD will not self-right unconscious people. The user may have to tilt their head back to avoid submerging their face. TYPE III has the same minimum buoyancy as TYPE II PFDs but is often purpose-designed for activities such as fishing or sport. Type III PFDs can in some cases automatically self-inflate when submerged in water.



A TYPE IV PFD, or throwable device, is meant for calm, inland waters with heavy vessel traffic and rapid assistance but can be used in open water as well. It is intended to be thrown to a person in the water and grasped and held by the user until saved. You can not wear a Type IV device. Type IV devices include items such as ring buoys and horseshoe buoys.



TYPE V, or “special use devices”, are intended for special activities such as water skiing, windsurfing, canyoning, or kayaking. TYPE V devices can be used only for the specified conditions they were designed for. They can be deck suits, work vests, board-sailing vests etc…. They are the most wearable devices for comfort and memorability but offer minimum safety. TYPE V devices may have features such as auto-inflate when submerged.

SOLAS lifejacket Standards

SOLAS Life Jackets

So let’s not stop there. We can also find manufacturers of safety equipment refer to the International Convention for the Safety of Life at Sea (SOLAS). In general terms, it governs the Safety of Life at Sea for signature countries which includes Australia.

Life jackets are covered under Chapter III – Life-saving appliances and arrangements: Life-saving appliances and arrangements, including requirements for lifeboats, rescue boats and life jackets according to the type of ship. The specific technical requirements are given in the International Life-Saving Appliance (LSA) Code. 

The code was enacted through The Navigation Act 2012: Marine Order 25 (Equipment — lifesaving) 2014.

Okay, nice to know but what does this look like on my boat, I hear you say.

Well, Safety of Life at Sea (SOLAS) lifejackets meet extremely high performance standards and are approved for use on all vessels. The SOLAS will self-right you very quickly so your face will be kept out of the water, even if you are knocked out. They come in two sizes: for persons 32 kg (70 lbs) and over or persons less than 32 kg. They are available in comfy and efficient inflatable models that can be automatically, manually or orally inflated. However, they also come in a bulky configuration as you would see on a passenger ship, etc. to reduce cost.

Australian Standards (AS) 

Australian Standards (AS)Lifejackets marketed in Australia must comply and display data about which Australian Standard (AS) they were manufactured to. The latest standard is AS 4758, which has replaced AS 1512-1996, AS 1499-1996 and AS 2260-1996. Lifejackets that meet these previous standards are no longer compliant and must be replaced where AS 4758 is set as the standard. For example, most States and Territories refer to AS 4758 as the local minimum standard.

But wait, there is more…

For most Australians, State or Territory legislation will be the overarching code to adhere to. There is, of course, a lot of overlap and you find that the local rules will make reference to a standard discussed above. However, this may differ from State-to-State.

Familiarise yourselves with your local rules which you can find here:

Inflatable Life Jackets

Most sailors prefer inflatable life jackets because they are extremely compact which increases your mobility around your vessel. Older style and often cheaper non-inflatable life jackets are cumbersome to wear and therefore, like anything else, may not be worn at all.

Automatic and manual inflation Life JacketInflatable life jackets can be classified as “AUTO” or “MANUAL“. Both have their pros and cons. Inflatable life jackets have the advantage of self-inflating when there is contact with water. This means that an unconscious sailor has a better opportunity to survive as there is no need to manually put the rip-cord to initiate inflation. On the other hand, I have seen many automatic inflation life jacket inflate spontaneously on deck when dealing with heavy weather on the fore-deck @ $30 a pop. They are also more expensive to service as there are more moving parts.

Automatic Inflating Life Jacket

Harness or non-harness?

Lifejacket with harnessMost coastal, off-shore and certainly ocean life jackets have a builtin harness. The harness is there to secure yourself to your yacht via a lifeline or tether and/or jack-lines to avoid a MOB situation. Harnesses come in different types. Some have a sewn-in loop made from strapping where others have a more robust system with stainless steel rings. Quality life jackets often have the anchor point in the centre of the jacket whereas economy brands often have the anchor point just off-centre.


Quality life jackets are often supplied with additional accessories. More expensive brands and 275N life jackets often have these accessories as standard whereas cheaper brands offer accessories as additional extras.

Accessories may include:

  • Lights – for better visibility as night
  • Whistle – for attracting attention
  • Spray-hood – for protecting against saltwater spray
  • Leg strap – for better fit and stability
  • Integrated AIS MOB1 unit – for increasing survivability

Travel Overseas

One more thing… Most jurisdictions have rules and regulations that govern vessel safety. However, for recreational yachties exploring the oceans of the world, there is little to worry about. These foreign countries will in almost all circumstances allow you to apply your local rules.

If you are from Australia, these rules are normally far more stringent than the country you are visiting. Nonetheless, make sure your lifejackets comply, are in good working order and serviced at their regular intervals.

Happy and safe sailing…
