Why is the number of anchor chains an odd number?
There are also many regulations that stipulate that the number of links in each anchor chain must be an odd number. Many people wonder, are odd and even numbers different? What is the difference between more and less? Let me answer it for you next.
Many people have seen the following thing, which is the Kenter shackle. It is generally used to link each section of the anchor chain. Of course, there are other ones such as D-rings, but the most commonly used one is the Kenter shackle because it is convenient.
It allows the anchor chain to be removed directly from where it is needed. In addition, Kenter shackles are much fatter and stronger than other links. We all know that each link of the anchor chain is 90 degrees vertical, that is, one link is horizontal and the other link is vertical. when designing the anchor chain plate of the windlass, there is also a horizontal groove and a vertical groove. When the sprocket pulls the anchor chain upward, it relies on the horizontal groove to drive it upward.
The Kenter shackle, also called “HALF SHACKLE”, can be disassembled to facilitate the connection of the anchor chain. Because the Kenter shackle is relatively fat, it can only lie in the horizontal groove and cannot be stuck in the vertical groove. If the vertical groove is made larger to accommodate it, other ordinary chain links will become loose inside. When the number of links in each link is an odd number, it can be ensured that the Kenter shackle connected to it is always on an even number, then it can be ensured that the Kenter shackle always falls in the horizontal groove. If the number of links is an even number, the Kenter shackle will be on the odd numbered ring for a while and the even numbered ring for a while, then it will have a horizontal groove for a while and a vertical groove for a while.
