Greece’s Diligent Holdings remains on a steady expansion course, which has catapulted the Athens-based company from a single-ship outfit a little more than two years ago to a midsize entity with nine bulkers.

Its latest move shows Diligent as bold as never before. The 58,000-dwt Pollux Star (built 2012), which joined the company’s fleet last week under its new name of Joker, represents its dearest acquisition so far.
