The Bremen-based owner has spent the past two years growing its fleet of secondhand and newbuilding boxships and is now said to have bought the 1,118-teu Vega Saturn (built 2008) for around $5.5m

The vessel previously belonged to the management of Hamburg-based Vega Reederei, which lists a dozen CV1100-design sisterships in its fleet.

It is the fourth acquisition by Harren since 2014.
