I've one of these, most people wouldnt think twice about spending £50 on a rod or reel but dont think about things like life jackets. Id rather float than sink.

A buoyancy aid is just that, an Aid to Buoyancy. It assumes the wearer can, to a degree, help themselves to either swim back to the shore or swim enough to get themselves back to a boat. It therefore assumes that help is close at hand, that the conscious wearer can swim or is comfortable enough in the water to wait for assistance and for this reason usually worn in sheltered waters.
A lifejacket may help if the wearer is unconscious or unable to help themselves and is almost always the preferred option for sailing coastal waters/offshore. The type of lifejacket worn will be determined by the conditions/ environment and the type of clothing worn and usually provide at least 150 Newtons.
