Re: Knox anchor anyone?

JonJo, please thank Mr. Knox for responding. Very interesting stuff. It would be great if he could provide links to more of his published anchor work on his website.

One thing that has always...

Re: Knox anchor anyone?

Got a note from Knox. The 13 kg (about 29 lbs) model costs £400 including VAT, and they are only available direct at the moment.

Re: Knox anchor anyone?

So, has anybody actually seen or handled a Knox anchor?

Re: Knox anchor anyone?

Another thing that is lacking in the discussion of anchor holding power is how much is needed. There are some charts out there by organizations like ABYC and other standards organizations, but as far...

Re: Knox anchor anyone?

The other thing about using a good bottom to test anchors is that is what many of us actually anchor in--I would venture to say that the vast majority of anchoring is not done by world cruisers in...

Re: Knox anchor anyone?

JonJo, I hope you didn't think I was being critical. I really appreciated the reports on your tests I have read, and I have downloaded and printed them out to keep. I was just trying to point out...

Re: Knox anchor anyone?

All of this brings up the age-old debate of how one could design and carry out an anchor test that would provide useful information for real-world use. It has been debated here on CF before, and of...

Re: Knox anchor anyone?

Can anyone figure out what red, blue, and black numbers are supposed to indicate in the anchor selection table for Knox anchors?

Re: Knox anchor anyone?

Re: Knox anchor anyone?

One of the problems people are having today is that real Bruce anchors are scarce, and some of the cheap knock-offs don't seem to be very strong or have the right shape. I suspect the originals were...

Re: Knox anchor anyone?

And, there is the perfect counterexample to all the anchor tests that indicate the Bruce is one of the worst anchors for holding power. Yet, experienced boaters seem to like them, at least in larger...

Re: Knox anchor anyone?

He had concluded in earlier tests that the Delta wasn't as good as the new-gen anchors so he left it out of this comparison. Not sure about the Fortress. Is it possible that the Fortress is not...

Re: Knox anchor anyone?

It is worth it hunting up Knox's articles, if you can find them. He has a list on his site, but not copies of them, which is a shame. But, here's one....

Knox anchor anyone?

Professor John Knox has written some very interesting articles about anchors and anchor tests, and apparently he is now producing and selling an anchor of his own design. There is more information on...
