TT,
The question to ask is how long had the tug been pushing on the shoulder at the angled aspect. The one photo that I posted is not instantaneous.
I have gone back and revisited Sal’s video and taken this screenshot. I would suggest as soon as the tug shifted to the shoulder, she commenced imparting sternway.
This particular CPP system, on failure, defaults to the current pitch setting…….it doesn’t change and we know that the Cuauhtemoc sped up significantly. Current and wind were not major contributors.
