It’s been a bad few weeks for Russian oligarchs and their superyachts.

Before Russia’s invasion of Ukraine, president Vladimir Putin reportedly moved his vessel Graceful from Germany to Russia to evade sanctions.

Then last month a Ukrainian seafarer tried to sink a yacht belonging to the boss of a Russian weapons company in Majorca.

Now Forbes has reported that sanctioned Russian billionaire Alisher Usmanov’s prized $600m ship Dilbar has been seized by German authorities at the Blohm + Voss shipyard in Hamburg.
