as of February 6.25. It's a very cold morning in northern Bosphorus.

I'm very close to the Black Sea.

Yorak Eshek is looking out across the Bosphorus Strait, the waterway that separates Europe and Asia in Istanbul.

I'm from Istanbul and I currently live in downtown downtown Istanbul by the Bosford, which is one of

world's busiest waterways.

And the reason York's been hanging out around here is because he's a ship spotter.

He's been helping the FT investigate Russia's so-called Shadow Fleet.

On this particularly blustery morning, he's armed with a camera, trying to spot a ship called Swift Sea Rider.

And I'm hoping to see Swift Sea Rider today, but the traffic slowed down due to rough weather.

And Swift Sea Rider changed names several times and changed flag since the Russian war on Ukraine has started.

And now I'm further interested with Swifsy Rider because it's one of the dark fleet vessels

identified by financial times.

York's talking about the ships that are helping Moscow circumvent sanctions that Western governments put on the country's oil exports.

These sanctions were put in place after Russian President Vladimir Putin launched a full-scale invasion of Ukraine three years ago.

From the banks of the Bosphorus, York and Istanbul can see these vessels sailing past him.

And yet, little is known about who owns these ships, how they were acquired, or who oversees

their operations.
