coley, my wife watched that programme and said that it should have been shown on national TV; most people who die in the water around the UK coast are on holiday and have little or no knowledge of how dangerous a beach can be. Anyone who knows Chesil Beach knows it is steeply shelving and has a very nasty, dumping shorebreak with a vicious undertow. Apparently the poor lads parents were bemaoaning the fact that there was not a sign saying the beach was dangerous - my argument is that just by asking someone they could have prevented their son's death.
I live in N Devon and am constantly astounded by the ignorance of tides and beach safety that holidaymakers demonstrate - does no-one have a sense of self-preservation any more?
