Choosing A Life Jacket

What life Jacket best suits your purpose

All life jackets have the buoyancy marked on them in Newton (N). This helps when deciding which life jacket to choose. Read the descriptions below to see which life jacket best suits your purpose.

50N LIFE JACKETS/Buoyancy Aid

A 50 Newton Personal Flotation Device (PFD) is classed as a buoyancy aid. It is intended for use by competent swimmers and swimmers who are near to the bank or shore, or by someone who can be rescued quickly if in need. These buoyancy aids are also suitable for use by water skiers, wake boarders, windsurfers, surfers and dinghy sailors. Buoyancy aids are exactly what they say they are.

They are not designed to keep you afloat when entering the water fully clothed but will be better suited to persons wearing wetsuits during water based activities.


100N Foam lifejackets are suitable for persons who are capable of helping themselves stay upright, with their head out of the water. 100 Newton foam lifejackets are more bulky than those with greater buoyancy. They are suitable for use in inshore and sheltered waters. 100 Newton lifejackets are not suitable for persons wearing heavy clothing or where there is a risk of becoming unconscious. Foam lifejackets are generally much cheaper than inflatable lifejackets.


150N lifejacket are suitable for general inshore/offshore and rough weather use. It will in most cases turn an unconscious person into a safe face up position. A 150 Newton lifejacket is suitable for use in general inshore & offshore use, fishing, boating and when working near water. Some lifejacket may exceed 150N buoyancy e.g. 165N or 180N.


275N lifejackets are suitable for offshore and extreme users, mostly used by people who work in offshore oil, Gas and fishing industries. 275 Newton lifejackets will self right an unconscious user leaving them with their face, mouth and nose out of the water.

Lifejacket Fitting

Wearing a properly fitted lifejacket is as important as wearing a lifejacket itself. Your lifejacket should be adjusted to your size with the lifejacket feeling firm around your body. A crotch strap should also be fitted to your lifejacket.

The crotch strap should run from the back of the life jacket down through your legs and be fastened at the front. The crotch strap will keep your lifejacket firmly secured to your body while in the water.

Lifejacket Care & Servicing

It is of the upmost importance to keep your life jacket serviced and in good condition. We recommend that inflatable life jackets should be serviced annually. Boat compartments are generally damp & humid areas, not the best place to leave your lifejacket. This especially applies if your lifejackets are automatic.

The best option for caring for your lifejacket is to place it in a life jacket bag and take it home with you to a dry environment after use. Manual and automatic Life jacket CO² Cylinders should be replaced if there are any signs of corrosion on the exterior of the cylinder.

If you have any questions about life jackets, or would like any recommendations for your needs, please feel free to contact us on or call us. Also note that the lifejackets will all specify their type and buoyancy value of Newtons.

We hope that this information will help you to choose suitable lifejackets and help you to maintain them in perfect working order.
