There are many things that can bring the anchor up backwards, not the least of which is a shift in the wind. The easy solution is a swivel, but failures are not unusual; my SS swivel had a nice interior crack that I noticed only when taking it apart to replace the anchor. Many sailors have abandoned swivels for this reason, and then wondered if they made a mistake when the anchor came up reversed most of the time. Never fear.
Notice the nice straight chain. No twist.
When connecting the anchor, observe that there are 4 rotation options. Unless you considered this at the time, you had only 1 chance in 4 of getting it right.
- If you are 180 degrees out of alignment, reattach inverted.
- If you are 90 degrees out of alignment, either add/subtract a shackle or clip one link.
