I didn't see the propellor wash of the ship in reverse. That problem would explain why the ship was moving so quickly astern. I assumed the cause was the current and after reading your post, I pulled out my Eldridge and sure enough, you got it right!

The NTSB/Coast Guard/Mexican Navy investigations should provide much more detail about the accident. I suspect that the captain and chief engineer will be questioned closely...

You mentioned your Garmin chartplotter. I have a Raymarine Axiom paired with an iPad. We also use Aqua Map, Navionics and iSailor. Additionally,. I have these things called paper charts. They're kind of old school but the shape of the planet doesn't change that much over time and they provide not only a backup to our electronics but they provide a big picture (small scale charts) of a given cruising area.

If you still venture onto the waters I wish you fair winds and following seas,
