Why is one anchor longer than the other?
If it is kept in the forecastle stores, it will occupy all the space and make it difficult to stow spare mooring ropes and wires. >> Hence on most ships either the port or starboard chain is longer by one shackle and that extra length is accounted for the spare shackle length.

What happens if an anchor gets stuck?
The other end of the line is tied to a float which, when released with the anchor, will float more or less vertically over the anchor’s position on the bottom. If the anchor gets stuck, hauling on the tripping line changes the anchor’s angle to the bottom and will usually free it.
