There was much confusion in the initial reports. Sabiti was Southbound, Sinopa Northbound. Sabiti, not Sinopa as originally (mis)reported, was the casualty. Her deep draft is atypical of Gulf oil exporting countries' tankers when Southbound through the canal, hence, perhaps, the confusion.
The bad news is that there will be retribution in kind, just as there was for IR655.
See Post#300 for the status quo and who won that particular round of the slugfest.
