From Germany’s North Sea ports to the French Riviera, open season has been declared on superyachts. Across Europe, authorities are hunting down luxury vessels tied to Russian oligarchs in the effort to inflict pain on Russian President Vladimir Putin’s allies.

In Marina di Carrara, a small Italian town on the Tuscan coast, one of the world’s biggest, newest and most expensive superyachts — called the Scheherazade — is under scrutiny by Italian police. Almost as long as a U.S. guided-missile destroyer, it dominates the waterfront.

The yacht, estimated by the website SuperYachtFan to cost about $700 million, has two helicopter decks and is studded with satellite domes. Inside, photos supplied by a former crew member show, is a swimming pool with a retractable cover that converts to a dance floor. Then there’s the fully equipped gym and gold-plated fixtures in the bathrooms.
