Fair leading around and pairing up winches is one way, the other way, which I know was used on a ship not long ago, is to drag the anchor into shallow water and then recover.
We are 4+ tons/shackle (shot) and anchor is 8 tons, 10 shots out would be 40 tons plus anchor is 48 tons, no way a single windlass is going to haul that.
Some ship routinely anchor in 100 meters, off Fujairah for example. Some ships with worn out gear or gear that is at min specs even 100 meters might be an issue.
Seattle has anchorages over 100 meters.
