Admittedly very naive question: would they have an anchor? Would it be long enough to hit the channel bed? Could dropping it have helped prevent, or at least slow down, the ship?
Or even if so was it just too late when it all went down and it wouldn’t have made a meaningful difference?
Given the forces involved, dropping anchor probably would probably massively damage the ship without sufficiently arresting its momentum, and add another uncontrollable variable into its trajectory.
The video linked above shows that the vessel had dropped anchor. However, anchors aren't very effective at that speed. They will just drag on the bottom or the chain will snap. There's just too much momentum.
