'I must get out into the free world', dissident who fled China on boat tells BBC

• The 68-year-old knew he was taking a huge risk trying to flee China by sea, but even then, he had underestimated the challenges of this journey.
• He was badly sunburned, his phone was running out of battery, and his portable charger had gone flat.
• Apart from the sky and the sea, there were no landmarks around him.
