[citation needed] Flensburger was acquired by Egon Oldendorff in March 1990 and then sold to the management in December 2008.

[3] In February 2019, Lars Windhorst's Sapinda Holding[4][5] acquired a 76% stake in the company and saved it from potential bankruptcy after the shipyard ran into financial difficulties due to multiple delays in the construction of the W. B.

There was also a delay of several months in the subsequent construction of the Honfleur, which was due to be delivered in 2019.

[10][11] Since 1 September 2020, the shipyard is owned by the Tennor Group, controlled by Lars Windhorst.

Subsequently, in August 2021 FSG acquired the neighboring Nobiskrug superyacht shipyard, located in Rendsburg.
