Cypriot owner Castor Maritime has sold its only capesize bulker in a deal linked by brokers to unknown Chinese interests.

The Nasdaq-listed company said the 180,200-dwt Magic Orion (built 2006) has gone for $17.4m to an unaffiliated third party.

The vessel is expected to be delivered to its new owner by the end of the first quarter, when Castor will book a net gain of $2m, minus any transaction costs.
