Michael Perham, 16, is the youngest person to have sailed across the Atlantic alone. He set out on his latest voyage from Gunwharf Quays, Portsmouth, on Saturday morning. He will be alone at sea for over four months and his only contact with family will be through satellite link-ups. Michael said: "I'm a little bit nervous but otherwise really, really excited. "It's just the feeling of being completely in control, relaxed and at one with nature. It's just fantastic. But you don't look forward to the fact you are alone for about four months." Psychologists have helped prepare him mentally for the challenges ahead and he said his experience crossing the Atlantic would also stand him in good stead. Money raised from the epic voyage will be donated to Save the Children and the Tall Ships Youth Trust.
