SuperYacht Paramour (now named DE DE)

The yacht Paramour was built as Heloval by CMN Yachts in 2002. She has a steel hull with an aluminum superstructure and can accommodate 10 guests in 5 staterooms. Her previous owner had her refitted in 2007 and put her up fore sale in 2010.

Michael O Keeffe

In 2011 she was acquired by Michael O’Keeffe. At that moment the yacht had an asking price of USD 12.95 million.


In 2012 Paramour was sent to Pure Superyacht Refit in Palma de Mallorca for an extensive refit. The lazarette was turned into a beach club, while a swim platform with underwater lights was added. Also a new sun deck was created with bars, a jacuzzi and a BBQ. Paramour was sold in 2015 and is now named DE DE. Do you know who owns DE DE? Please do send us a message.

Sold to Rio Tinto

This happened in 2011, when Rio Tinto acquired Riversdale Mining for approx. US$ 3.4 billion or USD 14 per share. O’Keeffe held 6.8 million shares, so the transaction netted him USD 95 million and a USD 10 million salary payment.

Champion Iron

O’Keeffe is still active in the mining industry, through Riversdale Resources which owns coal mines in the US and Canada. He is also Chairman and CEO of Champion Iron Limited, active in iron ore exploration in Canada. O’Keeffe owns 6.3 million shares and 1 million option in Champion Iron Ore.
