A rise in average day rates of over 10% for its 50-strong fleet helped push the New York-listed shipowner to net income of $23.8m, or $0.65 per share, in the three months to 30 June.

That figure was just over twice the level seen in the second leg of 2012.

Operating income jumped by over 50% to $52.2m in the second quarter from $33.8m in the year earlier period.
