The world's largest superyacht is confiscated by German authorities

Russian millionaires are having a hard time due to sanctions imposed by Europe and the United States on ultra-rich Russians who have close ties to President Vladimir Putin. This time Russian billionaire Alisher Usmanov was stripped of a luxury superyacht in Germany.

Hamburg authorities seized the Dilbar superyacht after determining that it was, in fact, the legal property of his sister, Gulbakhor Ismailova . Another billionaire who is also subject to Western sanctions for the Russian invasion of Ukraine.

The yacht is named after their mother of these wealthy brothers. Usmanov owns a major stake in USM , a Russian investment group with stakes in Metalloinvest, one of the world's largest iron ore producers, and the telecommunications company MegaFon .

Furthermore, he is the sixth richest Russian with a fortune of $19 billion, according to the Bloomberg Billionaires Index.

It should be noted that superyachts and other displays of wealth among Russia's elite have drawn especially intense scrutiny after Russia declared war on Ukraine.

Germany's federal crime office said on Wednesday that despite efforts at what it called "concealment on the high seas," it had managed to identify the yacht's owner, Usmanov's sister.

In a tweet the German authority stated: "The luxury yacht Dilbar is therefore subject to the sanctions law and could be legally seized in Hamburg." And once this luxury yacht has been seized it cannot be "sold, leased or pledged as collateral".
