Stalwart Management is said to have shed the last vessel in its original chemical tanker fleet, which would complete a pivot towards larger vessels.

The Dimitrios Souravlas-led company has sold the 23,300-dwt St Aqua (built 2006) to unidentified buyers for about $12m, several Greek and international brokers report.

Company executives were not available for comment.

Some shipping sources in Athens doubted a sale had taken place, and the St Aqua still features as unsold on the company’s website.
