Photos show luxury boat with 50m pool and water slides near Kim Jong Un's summer retreat
An 80m (263ft) luxury vessel has been repeatedly spotted in satellite images off North Korea's Wonsan coast from July to mid-October this year.
What stands out is the 50m swimming pool along the deck, with a cluster of waterslides at one end.
After sitting idle for months at a maintenance facility, it relocated in early July to waters off a strip of coastline known as the Kalma Peninsula.
This is close to Wonsan, a seaside resort with a sprawling villa used by North Korean leader Kim Jong Un and his family.
It was not the only large vessel on the move. A handful of others were also repeatedly seen near Kim's villa, in satellite images analysed by the BBC.
The vessels are widely believed to be used by Kim and his family. Former North Korean officials, defectors and experts say it would be difficult for anyone unconnected to the regime's leadership to own or freely use vessels of this size.
"In winter, they would keep them at the shipyard. When summer came, they would bring them out and move them to Kim Jong Un's villa or towards Kalma, and use them for swimming and recreation," says Ri Jong Ho.
Ri was once an official at the Workers' Party's Office 39, which is believed to be involved in raising and managing foreign currency for the leadership.
The wealth of those who sit at the top of the secretive North Korean dictatorship is just as hard to pin down as the country's economic figures.
The United Nations and others rely on estimates to classify North Korea as one of the world's poorest countries, with an especially large military budget that funds a sanctioned nuclear programme.
