Why emergency anchor release would require power, i don't know. I would think it should not, as loss of power could be the whole reason a dropped anchor(s) might be required. Mechanical sears should be possible to minimize force required to enable release, but i have not designed one.
In any event, I thank you for your excellent commentary.
It may have been dropped, but it may have been too long that it won’t matter. They won’t just STOP. Not the way reality works. There is space and time involved. It’s not a cartoon. Never mind an anchor doesn’t keep it from drifting different directions. It’d need at least 3 strategically placed anchors for that.
