Croatian owner Atlantska Plovidba has revealed another bulker sale as it reported a big jump in earnings.

The Zagreb-listed company said it had signed a deal to offload the 57,000-dwt supramax AP Ston (built 2012) for $19.5m to an unnamed buyer.

The vessel will be delivered to the new owner in the last quarter of this year, but until then will be managed by Atlantska.
