Greek shipowner Stealth Maritime has concluded time charters for up to two years for a pair of aframax tankers.

Chief executive Lambros Babilis confirmed the charters, though he declined to disclose the charterer or rates on the deals.

Brokers said the Vafias family-backed company fixed the 112,000-dwt Chrysalis and the Gstaad Grace (both built 2010) to trader Trafigura for one year at $22,500 per day each, with an option for one more year at $27,500 per day.

Chrysalis has been on charter to Maersk Tankers at $13,750 per day in a contract that included a profit share element. Gstaad Grace has been on charter to Cyprus-based Solal Shipping at $15,000 per day.

Stealth purchased the Gstaad Grace from the fleet of the collapsed Toisa group in May last year, when it was the United Grace, for $22m. The shipowner picked up the Chrysalis as a newbuilding resale for $56m in 2010.

Stealth Maritime has a fleet of 11 aframax tankers with an average age of 10 years.

Another Vafias-controlled company, Brave Maritime Corp, is listed with two LPG carriers, an aframax tanker and the 33,000-dwt bulker Neptulus (built 2012)
