Nikolas D Pateras is adding up to four more vessels to his steadily expanding feeder boxship fleet.

Clients of the Greek owner’s Athens-based Contships have acquired the 1,118-teu sisterships Vega Lupus and Vega Luna (both built 2006). Executives at Contships confirmed the transaction but declined to disclose the price at which their company purchased the Qingshan Shipyard-built units.

VesselsValue suggests the Vega Lupus and Vega Luna are currently worth about $7.3m
