More than $2 billion worth of mega yachts linked to Russian billionaires have been seized in Europe since Russian President Vladimir Putin launched a war on Ukraine.

The EU and the UK have seized at least 13 boats worth between $8 million and $606 million as officials continue to sanction Russia's elite, according to the outlet.

The US, the UK and the EU imposed economic sanctions on Russian tycoons, many of whom moved their mega yachts to regions where they can't be seized.

It can be difficult to pin down the owners of the boats, but public speculation about the owner is usually sufficient for a seizure.

According to reports, Spain is holding four of these vessels, including the $8 million Lady Anastasia linked to Alexander Mikheev, the $95 million Valerie linked to Sergei Chemezov, and the $468 million yacht Crescent linked to Igor Sechin.

The Amore Vero is a yacht worth $125 million that is linked to Sechin. The country has a $22 million Little Bear and a $77 million Big Bear.

The $34 million Lady M is linked to Alexei Mordashov, the $575 million Sailing Yacht A is linked to Andrey Melnichenko, and the $38 million Lena is linked to Gennady Timchenko.

The Dilbar is the largest ship in Germany and is worth $606 million.

The $68 million Axioma, which is linked to Dmitry Pumpyansky, is held by Gibraltar, while England has taken control of the $38 million Phi.
