The volunteers of the Royal National Lifeboat Institution staff more than 230 stations covering even the most far-flung areas of Britain's coastline, but the busiest station by far is actually miles from the sea, on the River Thames in central London. It was established after the Marchioness pleasure cruiser sank in 1989, claiming the lives of more than 50 people. While it might look benign, the Thames is actually one of the most dangerous stretches of water in the UK. The volunteers are called from their beds in the middle of the night to try to rescue two students who have jumped naked into the river while high on LSD. At the coast in Newquay, the volunteers and coastguard helicopter are scrambled to try and help a 12-year-old boy on a Cub Scout trip who has fallen badly and has suspected spinal damage. Eastbourne lifeboat station covers a stretch of coastline which includes Beachy Head, so they have had to become more familiar with death than most. Recovering the body of someone who has taken their own life is a duty the volunteers see as an important service to the family who have lost a loved one.
