Nasdaq-quoted Capital paid $0.2365 per unit for the quarter on its common units and $0.21775 per unit on its Class B units, up $0.002 on both classes.

Jerry Kalogiratos, who sits as both chief executive and chief financial officer, says with its latest dropdowns funded and the some ships chartered at stronger rates the distribution should continue to grow by between 2% and 3% per annum in the foreseeable future.

"Although 2-3% may seem light, when added to the current yield of 12% the potential total return is similar to that of those MLPs viewed to have ambitious growth targets," said Jon Chappell of Evercore ISI.

It came as Capital announced a $14.11m profit for the three months to the end of June, against a gain of $7.82m in the same period a year ago.

Earnings per unit of $0.09 were in line with market expectations.

Revenue rose from $47.4m to $54.4m thanks to an improving tanker market and a larger fleet.
