Euroseas, an owner of 17 feeder and intermediate container ships, has seen a client pull back from one of its highest-paying charters.

The company disclosed on Wednesday it is “pursuing legal action” against Continental Shipping Line, Singapore (CSL), which had the 1,439-teu Aegean Express (built 1997) under charter.

In January, CSL “repudiated its charter as the vessel was completing its scheduled drydock,” Euroseas said in a release of fourth-quarter results.
