New Anchor

New to me anyway.

Knox Anchors

Super Sarca roll bar. Skinny like a Super Sarca.
Danforth fluke shape. Except slightly concave.
Claw shank shape. Plate material like a Rocna or Supreme .. but stronger it seems.
Ears like a Supreme or Rocna.

Extreme claims for performance. But I have a strong feeling it won’t be available at West Marine.

Have a look.

Read their story, they anchored in force 10 winds with their CQR and didn’t drag. So they decided to design a new anchor. Only a Brit could write that and expect others to believe it makes sense.

Slight oversimplification. They also had another anchor out and they kept the engine running. Odd motivation, nevertheless.

Just looking at it and applying what I may know about anchors compels me to buy one. Never (that I can recall) have I said that. It’s got lots of features that add up to great things. This could be the next plateau in anchor design. Probably due to high quality (strong) sheetmetal in a shape that benefits both strength and performance.
I e-mailed them asking where the Knox could be had it the US.

To me, it looks exactly like a Manson Supreme or Rocna knock-off. Therefore hard to accept the performance figures being so much better. I'd beware the claims a bit, Eric. But no doubt it would work well, as the anchor types it emulates have already proven that. So...next question is price and availability, I guess.

KnoxAnchor - has anyone any experience of using one?

To me it looks like the raided the sarca and danforth scrap bin and created an anchor with two blades causing weakness and prone to bending.

Has there ever been a new anchor you weren't compelled to try out? Anxious to hear your review. They should send you one free just for you to review it. Tell them you'll post your findings on Trawler Forum.

Good Grief!
But, I think I still like the original Sarca.

Simi,
Look closly at the way it uses the plate or sheetmetal to form triangles. The fluke is made of two pcs forming a triangle.
I was skeptical about the shank re side loads. But if it’s strong enough steel? Same kind of shank (plate) is used on many popular newer anchors and w the exception of Rocna’s use of mild steel all have performed well. Notice that they don’t make SS anchors saying SS is not strong enough.

One thing that does concern me is balance. The shank looks heavy. That could cause setting problems. May take awhile for that to be settled.

I don’t understand the slot in the ctr of the fluke yet. One would think the fluke would be stronger w/o it and holding power to be greater. Perhaps the slot is like Rex’s holes and far smaller slots. But the fluke shape has been proven since 1938 .. I’m refering to the Danforth of course.

If I was to build it I’d do so w less throat angle.

Just saw your post Bruce,
Reflect on the fact that the original Sarca was almost the same as the Knox but w the fluke upside down. I’ve seen pics of the original Sarca that was concave. And Rex says the original had more holding power but tore up the bottom like other anchors. Got to admit it looks more like a Sarca than anything else. And the Sarca is still my favorite anchor.

This quote from the website does not fill me with confidence. 5 meters is a long plough before it holds and rights itself.
"The Knox anchor will start to bury itself immediately and develop maximum hold after it has ploughed approximately 5 metres (depending upon bottom conditions). By that time it should have rotated to a vertical position, and should be completely buried."
Are you sure about this one, Eric?

The anchor markup on a ton of steel is too hard for folks to ignore.

Bruce,
Yes I could have made a fool of myself on this one. Been reall busy and haven’t had time to look much. My response yesterday is somewhat kneejerk and some of the things they print is at least questionable. Stumbled onto it on FB through one of my European friends. It poped up after I commented on a Navy anchor in a picturue. The guy posted a link.

My first response was “that open slot between the two flukes (like a Danforth) is crazy weak. Then I saw the huge shank. Yup there’s lots of questionable stuff there. I’ll take more time looking now and consider what whizzed by me yesterday. Don’t like the looks of that winch on a plywood board and I’m very skeptical of dragging anchors on beaches. I may resort to some of that for my modded Claw for preliminary “will it rotate” evaluation. But I think my Claw will turn out to be a mud packer. The Knox is very interesting and a bit hard to judge as it’s so different. And I am attracted to things different. As far as I know I’m the only one here w an XYZ anchor. Sorry no edit ...

Every new anchor on the market is the "best" and we should all do away with our tried and true anchors that have held us in place for hundreds of nights to upgrade to them.

Hey guys lighten up.
I started this thread to offer something interesting. Something to think about and analyze and compare to other anchors. Too many people here think everything is an debate over what’s the best thing to buy. As if there is a best thing that will fit for everybody. And “I’ve got the best” just starts arguments.

Re anchors there’s “will it fit nicely on my bow” or “will it work on my rocky bottom” ..... things that are unique often swing the purchase of anchors and other products.

So what do you see as a plus or minus in this interesting new anchor? Something that hasn’t been mentioned is that the roll bar on the Knox is further fwd possibly further than any other RB anchor. For example the Rocna’s RB is well aft. Several inches difference. Food for thought?

PS,
One of the guys on FB just said “I have anchored many many times with both Rocna and Knox anchors,I can not tell the difference between them. Both are fantastic and a million light years away from the CQRs of yesterday”
