"UAL Nigeria" reached Las Palmas in 7 days, 3 hrs and 40 min. ref original picture info. She later left Las Palmas for Alob, Angola; ETA in abt 11 days.

In Larvik "UAL Nigeria" had two new, red painted small tugs as deck cargo (see picture). One of them named "Red Ant." Anyone who can tell if that tug has been unloaded in Las Palmas, og perhaps later, in Angola ( abt September 21st).
