On arrival, the lifeboat crew found the Bulgarian national on the dinghy was "exceedingly cold, wet and violently ill" yet was refusing their assistance.
They soon ascertained that the 30-year-old man, who has a US visa, had bought the dinghy earlier that day, packed it with some meagre supplies – without any suitable safety equipment or navigation aids – and set out to cross the Atlantic.
"He would have died [if we left him there," said lifeboat crewman Pete Dadds. "He was severely sea sick, he had the first signs of hypothermia and his boat was filling up with water."
