The following is some useful information and advice that may help you decide 
What to Wear for Personal Safety 

(and the Difference Between Lifejackets and Buoyancy Aids)

Some Definitions

CE Mark
We, as other manufacturers, can only sell lifejackets, buoyancy aids and safety harnesses that have been tested to the latest CE European specifications and carry the
CE mark of approval, this ensures that they meet the new European Standards (similar to the BSI kite mark)

Newton
A Newton
is a measured unit of force. 10 Newtons are approximately equal to 1 Kilo (2.2 lbs) of buoyancy. They are the new EC standard. The higher the Newton number, the more buoyancy provided.

 
The buoyancy quoted is for adult sizes only. Smaller sizes have proportionally less buoyancy.

There are four levels of Buoyancy Ratings

275 NEWTON LIFEJACKET 62lbs/28kg buoyancy
Suitable for swimmers and non-swimmers

  • A high performance device for offshore and severe conditions, when maximum protection is required or where heavy waterproof clothing is worn
  • They give improved assurance of safety from drowning to people who are not able to help themselves
  • While they cannot be guaranteed to self-right an unconscious user wearing heavy waterproofs, the buoyancy they provide should ensure they will in the great majority of cases
 

150 NEWTON LIFEJACKET 33lbs/16kg
Suitable for swimmers and non-swimmers

  • For use in all but the most severe weather conditions
  • They will give reasonable assurance of safety from drowning to people who are not fully capable to help themselves
  • May not immediately self-right an unconscious user wearing heavy waterproof clothing
  • Equivalent performance to previous BSI approved jackets

100 NEWTON LIFEJACKETS 23lbs/11kg
Suitable for swimmers

  • They will give reasonable assurance of safety from drowning in relatively calm waters
  • Not guaranteed to self-right an unconscious user wearing heavy waterproof clothing and should not be expected to protect the airway of an unconscious person in rough water

50 NEWTON BUOYANCY AID 11lbs/5.5kg
Only suitable for competent swimmers

  • Sheltered water use where close help is at hand
  • Only provide support to a conscious person who can help themselves

 So that’s the definitions - Some practical considerations 

150 newtons lifejacket available as manual or auto inflation

easy to wear, not bulky, not too heavy, to work when you are in the water the lifejacket must be fully inflated, the buoyancy pushes you on to your back to help keep your mouth clear of the water, you would find it difficult to climb back in a boat unaided.

( if there is a chance you may fall in unconscious eg from the boom on yacht etc banging your head, use an auto inflation – you will not be able to inflate a manual inflation life jacket if you are unconscious).

When the life jacket has been inflated you will need to deflate and order a new cartridge

This lifejacket is not designed for someone in a dinghy who is liable to fall in or capsize often.   


100 newtons lifejacket

Tends to be more bulky, although it is usually lightweight.  Again, the buoyancy is pushing you on to your back to help keep your mouth clear of the water.

Likewise, we would suggest, if buying for a child under 5-6yrs, you should maybe buy a 100N lifejacket, even if they can swim, because they may well receive quite a fright if they fall out of a boat into cold water, and may panic which might affect their swimming. 


50 newtons buoyancy aid
This is an aid to swimming, since the buoyancy is round the body rather than just on the chest front.

It is easy to wear, not bulky, cut high so it is easy to sit down, and you are manoeuverable in the water, and climbing back in a boat after a capsize is not a problem.


However it is only an aid to swimming and for competent swimmers

Points for thought

  • if you can't swim you  need a lifejacket

  • if you are under a capsised boat the more buoyancy you have on, the more difficult it is to swim out from under the boat.

  • in a dinghy, the collar of a 100N lifejacket maybe a hindrance, eg getting caught on the kicking strap etc  

We realise this is a very important subject and if you would like further advice please contact us.
