Reuben Brothers | Siren

The Rueben Brothers are certainly from one of the wealthiest families in the world. They placed investment money on a total of five superyachts, but they sold four of them after some business transactions. They are currently left with the beautiful 240-foot boat called Siren. For $70 million, the ship boasts seven suites for up to 14 guests and nine cabins capable of housing a staff of 18. The impressive main salon is a popular lounge area, as well as spacious and stylish entertainment venues, with a long dining table for formal dinners.

Built by Nobiskrug and designed by Newcruise, Siren has a maximum speed of 18 knots and an MTU 16V400 engine. The siblings have a lot of businesses, including real estate, shopping and leisure places, coal and iron mines, and even the London Oxford Airport. Their company is also one of the largest producers of aluminum in the world.
