One thing that should be mentioned. The anchor windless is a tool to lower and raise the anchor. It is not intended to support the load of the boat while anchored or be used to drag the boat up to the anchor when retrieving it. One the anchor is down and before setting the anchor a bridal if on a cat or a snubber if on a monohull needs to be attached to the anchor chgain to support the loads from the boat. The anchor chain from the snubber to the windless should be let out at that point so it is slack with no load.
In addition to releaving the load on the windless the snubber or bridal will provide some give and cushion jolts to the anchor helping insure it will stay set. You will also enjoy a quiet night without chain rattle as a side benefit.
