Ibiza and other Mediterranean party islands that have long been popular holiday destinations for the ultra-rich, are not included in the list of places where superyachts are staying.

The Balearic Sea, which lies off the east cost of Spain and is home to Ibiza, Menorca, and Majorca, has only been visited by one yacht this spring, a $600 million yacht linked to Roman Abramovich.

At least nine boats owned by Russian billionaires stopped at islands in the Balearic Sea in March and April of those years, sometimes visiting the area more than once.

European Union countries and other Western nations are trying to seize luxury assets belonging to Russian billionaires.

The Solaris set sail for Montenegro on March 8 after being repaired in a shipyard in Barcelona. This is the only time a Russian yacht has crossed the Balearic Sea since the beginning of the Ukraine war.

Spanish authorities helped the US seize a $90 million yach Tango in Mallorca, which was linked to Viktor Vekselberg. The boats belonging to Sechin and Mikheev were seized by Spain.

There is a lower risk of seizure when Solaris is in Turkish waters. Eclipse is one of the ships belonging to Russian billionaires and is located in Turkey.
