I agree with your sensible posts but think you are silly trying to convince stupid people to take appropriate safety precautions to the risks they are in reality exposed to.
Some people are too stupid to appreciate a minimal risk situation yet probably expose their families to far greater risk when they are at the wheel of a car (unless they insist that they are one of the 99.9% of drivers that are above average).
I suspect that a number are obsessed with the need to spend £1,000's on buying and servicing their liferafts yet skimp on engine maintenance or a rigging survey and probably completely miss the need to give a priority for certain items of safety kit and will only be happy when legislation is bought in to compel every watercraft to have a Liferaft.
Rather scuppers the happy individuals that got afloat for £5,000 in this months YM!!
