April 27 (Reuters) - A superyacht linked to sanctioned Russian billionaire Alexey Mordashov sailed through the Strait of Hormuz on Saturday, shipping data showed, one of very few vessels to transit the blockaded shipping lane at the heart of the U.S.-Iran conflict.
Nord - a 142-meter (465-foot) yacht worth over $500 million - left a Dubai marina at around 1400 GMT on Friday, crossed the strait on Saturday morning, and arrived in Muscat early on Sunday, according to data on the MarineTraffic platform.
It is not clear how the multi-deck pleasure vessel gained permission to use the route. Since February, Iran has severely restricted traffic through the strait, which typically handles around one-fifth of the world's oil supply.
A representative of steel magnate Mordashov declined to comment on Monday.
Just a few, mainly merchant vessels, have been passing daily through the crucial waterway at the entrance to the Gulf as Washington and Tehran maintain an uneasy ceasefire. This represents a fraction of the average 125 to 140 daily passages before the Iran war began on February 28.
In a countermeasure, the U.S. has imposed a blockade of Iranian ports.
Russia and Iran are longstanding allies and have become closer in recent years, including via a 2025 treaty that strengthened intelligence and security cooperation.
Iranian Foreign Minister Abbas Araqchi arrived in Russia to meet President Vladimir Putin on Monday after discussions with mediators in Pakistan and Oman over the weekend.
Mordashov, known to be close to Putin, is not officially listed as the owner of Nord. But shipping data and Russian corporate records from 2025 show the vessel was registered to a Russian firm owned by his wife in 2022. This firm is registered in the Russian town of Cherepovets, where Mordashov's steelmaker Severstal is also registered.
Mordashov was among a number of Russians sanctioned by the United States and European Union after Russia's invasion of Ukraine for their links to Putin.
One of the largest yachts in the world, Nord has 20 staterooms, a swimming pool, a helipad and a submarine, according to industry publisher Superyacht Times.
