China's Rewood Ocean Shipping Co (Rosco) is in talks to sell the single capesize in its fleet of 11 bulkers, in a deal bound to raise speculation about whether this might be the opening shot in a wider sale campaign.

Several brokers in the US and Greece said the company is selling the 181,500-dwt Rosco Maple (built 2010) to US-listed Seanergy Maritime for $33.75m.

The Japanese-built vessel is equipped with a ballast water treatment system, has no scrubber and is said to be due for delivery to its new owners in November.
