Aratere
That is a photoshop pic - The newspaper article at the time said it was an artist impression of the actual 50 deg. roll.
The Aratere had to stear an unfavorable angle in the heavy southerly, to clear Cape Terawhiti on a course to the northern entrance to the sounds - There were no off board cameras near the roll area.
With shifted cargo and still listing they had to keep heading north until almost Kapiti Island untill it was safe to turn and head back south.
