July 26 (Reuters) - The Baltic Exchange’s main sea freight index fell for a fourth straight session on Friday, driving it to its worst weekly loss in six months on abundant availability of ships in the Atlantic region.
* The Baltic index, which tracks rates for ships ferrying dry bulk commodities, fell 0.5%, or 10 points, to 1,937 points. The index fell 10.7%, worst weekly performance since week-ending Feb. 1.
* The index has still more than tripled since February, mainly driven by strong demand for vessels that ship iron ore from Brazil into China.
* The capesize index rose 38 points, or 1.1%, to 3,647 points. For the week, capesize index was down 16.7%, its worst since week-ending March 29.

* The panamax index fell 71 points, or 3.3%, to 2,109 points.
* Average daily earnings for panamaxes, which usually carry coal or grain cargoes of about 60,000 tonnes to 70,000 tonnes, decreased $562 to $16,869.
