Somehow it has to be explained how the ship miraculously turned the last minute and hit a vulnerable part of the bridge.
00:39:00 Ship departed from the Seagirt Marine Terminal
01:07:00 Ship entered the Fort McHenry Channel [NOAA Nautical Chart 12281]
01:24:00 Ship traveling at a heading of 141 at about 9.2 mph [8 knots]
01:24:59 Censor data stopped recording, but audio recording continued
01:26:02 Censor data recording resumed
01:26:39 Pilot made a radio call for tugs to assist
01:27:04 Pilot ordered an anchor drop
01:27:25 Pilot radioed that all power was lost and asked for bridge to be closed
01:29:00 Ship was traveling less than 8 mph [less than 7 knots]
01:29:33 VDR recorded sounds consistent with crash, and dash cameras show bridge lights go out

My latest guess, is that there was enough out-bound tide current from the Curtis Bay Channel - starboard side of MV Dali - as the ship entered the junction of that channel and Fort McHenry Channel used by the ship.
Such that, the ship bow was pushed a bit to port (left) . . . and the ship's helm responded by a touch of right rudder to compensate - that sent the stern a bit to port (left).
Followed by, the bow was past the Curtis Bay Channel current force, while the stern was still in that current effect.
A trivial adjustment in more open waters, but too late to fix in so short a distance to the bridge - complicated by the "mechanical issues" that coincide with power outage and sensor outage.
