Bridgepoint, the mid-market buy-out firm, has doubled its investment in Navimo, the French marine leisure equipment supplier, after five years following the €120m ($148.2m) sale to rival Duke Street Capital.

Bridgepoint originally acquired Plastimo, a security and navigational equipment company, in July 1999 and renamed it Navimo following a series of other acquisitions, such as Max Power and XM. The group has 680 employees, annual sales of €120m and is profitable.
