Knox Anchor 9KG

The best choice for 20 to 30 foot yachts (6 - 9m).

Light vessels (5 tonnes or less) up to 35 feet trying to minimise weight on board can be safely held by the 9kg size.

Knox Anchor 13KG

The 13kg size is the best option for the majority of 30 to 40 foot vessels.

For heavier vessels (over 10 tonnes) and closer to 40 foot long an 18kg size would be a better choice.

Looking for another size?

We stock anchors down to 6.5kg size for vessels smaller than 20ft.

We also manufacture stock in 18kg and 27kg size. If your vessel is over 40 foot or expected to carry heavy loads (above 10 tonnes) then please contact us about these models.

Is my anchor heavy enough?

As seen from the table and charts comparing anchor performance, the holding force to weight ratios of modern anchors can be many times those of older designs such as the Bruce, CQR and Delta. Therefore do not be surprised if your recommended Knox anchor is lighter than the anchor it is replacing.

If you are replacing your current anchor with a high performance Knox anchor, you have the choice of using a lighter anchor of similar holding power or keeping to the previous weight and gaining much greater holding power.

This Knox anchor size recommendations here are suitable for use in winds up to force 8 when there are moderate non-breaking waves. For more severe conditions choose a heavier Knox Anchor.

Will my anchor fit?

Wherever you store your anchor onboard, it's important that you know it will fit. The dimensions of our range of Knox Anchors are shown in the scale drawings and the table below to help you. 

Our policy is that if you have made reasonable attempts to ensure a fit by checking dimensions before hand, and your new Knox Anchor doesn't, we'll refund your purchase price on the return of the anchor in un-used condition.
