OK sure, but again:
1. Marine diesel engines do not shut off when they lose electrical power. They have enough battery power to keep running for a bit, and
2. The Dali was required by International Maritime Organization regulations (and US CFRs) to have an Emergency Generator that comes on line automatically within 45 sec and powers, among other things, engines, steering, and navigational equipment.
Those things are required in ship design for exactly this reason, so if you lose an SSDG you can navigate the vessel safely until power is restored. I'm confident watching that video that the E Gen didn't come on as it was supposed to, but unless the whole thing was just an unmaintained POS (a possible scenario) this doesn't add up. This is multiple failures in multiple non connected systems, and we still don't have an explanation as to what caused that abrupt turn to starboard right when the power came on the first time. The internet can *expletive deleted*ck right off with "wind and current". You don't drift in a straight line while dark ship for a full minute, then as soon as the power comes on have the current swing your bow 15*-20* in 40 secs.
