Sumida, container ship location

[chasd147]

Been tracking Sumida on sailwx , just another container ship(Maersk?), for awhile, simple curiosity.   Sails between Santos Brasil & NYNY, some stops on the way.  Last report 1/23, between Ven. & Haiti.  She stops reporting for weeks at a time.   Sure can be many good reasons.  Could be returning to Santos by now?  Does she have a website?
