What size anchor chain should you use?

What sizes are available?

You should only use Short Link chain for Anchor Winches / Windlass in Australian. This chain is readily available in 6mm, 8mm, 10mm and 13mm.

Are all Short link chains the same?

Unfortunately not.  A lot of chain on the market in Australian is not tested and not graded. You should look for Grade L chain, it is suitable for lifting purposes, it will fit correctly on your gypsy, and it’s manufactured to AS 2321.

What chain length is need to secure your boat?

In normal anchoring conditions you should drop around 2 to 3 times the depth i.e. the depth is 10m, use 20m - 30m of chain.

In poor anchoring conditions you should drop around 3 to 4 times the depth i.e. the depth is 10m, use 30m - 40m of chain.

In extreme anchoring conditions you should drop everything you have and make sure the end of the chain is secured to the boat.

What size chain should I use?
