Bigger is not always better

With the new generation anchors, a bigger anchor is not always better.

 

New generation anchors are designed and built to dive deep.  If you choose to use a new generation anchor that is too big for your boat you are diminishing the ability of your anchor to dive deep enough to hold your boat the way it was designed.

 

A bigger anchor will develop no more hold than a smaller one if not buried properly.  The burial of your anchor is determined by your engine power or windage.  If you can set a 15kg anchor to 300kg hold then a 20kg anchor will develop the same hold under the same conditions - except the 20kg anchor will be set more shallow.  Therefore we urge you to follow our sizing recommendation, these recommendations are a result of numerous tests made on our anchors over the years  - there is no need to oversize.

An anchor that is not buried deeply and dragging its chain with it might encounter a few issues:

 

  1. An unburied shank will not act as a vertical fluke which may reduce the resistance of the anchor to yawing.

 

  1. In light winds, a shallow set anchor could be prone to the chain getting under the shank and tripping the anchor.
  2. A large anchor that cannot be deeply set may trip easily and you have no guarantee that it will re-set cleanly by itself.
  3. A too-large anchor will not have its full fluke buried and therefore will not use its full fluke area a thing that will reduce its holding power.
  4. An anchor that is not fully buried does not have the fluke/shackle hole optimum angle designed to its pule direction and also, will not have its maximum holding power when puled.

 

So when choosing an anchor that is too big, it is not just the inconvenience of using it, affecting your windlass, your pulpit, and your back (or your spouse's back - then you will definitely suffer), it is above all not safe.
