A new anchor design

I noticed this slightly different design made in Oz.

Anchor and dinghy designs are actually religions, with small but defiant congregations.

Interesting design.. a little bit similar to the fluke of the Delta Anchor?

From the price list, it seems that the anchor is made of Aluminum, an interesting alternative to the Fortress anchor? but it also seems that the sizes are limited to 3 sizes, for boats up to 6,5 meters??

But 8 years of research and development, to develop this anchor?? I think they have to change their computer for at least a "Pentium" Chip, more powerfull and more fast!..

Larger sizes available

The advert does seem misleading but the pic plainly shows larger sizes. I have enquired for my own yacht and will advise cost.
No involvement with the company.
Cannot see how the small fluke half way up the shaft helps especially but presumably some rationale.

Hmmm.... not to sure.

Quick thoughts and only from sussing the website but blended with some background in anchor design of my own. So I maybe horribly wrong.

Vid and photos not too crash hot. Just about anything can set well in soft bottoms like shown. Not to mention setting any anchor at 100:1 scope isn't hard

Cons -
Old school thinking, which I do believe has pretty much run it's course.
Small looking flukes (foot)
Open shank angle so may struggle in the hard stuff.
Guessing (on weights given) it has a very poor tip weight so may struggle to get setting action happening.
They mention thin shanks and in alloy? That hasn't proven to good in the past on some designs.
That plate thing 1//2 way up the shank WILL cause many fitting issues.

Quote:
This new position greatly reduces the vertical force needed to change the direction of the anchor upward when retrieving it, thus making it easer to pull free from the sea bed, and at the same time doing less damage to the environment and minimizing the chances of becoming permanently hooked up.
They have designed it to break out easy with less up force??? Errr... Anyone else find that spooky?

Pros -
Lite weight. Always good for the racers.
Small so store well (??)
Good pricing and far superior to the over priced Fortress (in my opinion)
Does sort of look a bit sexy in that old school way.
Open shank angle so may do well in the soft sloppy stuff.

The country the anchors are made in does have a baring on designs often. The Aussies don't boat a lot in real wild weather and do do a lot in shallow sheltered waters. They (not just Cooper) tend to not put the curry on gear like many other nations do, a nature of the beast sort of thing. There are a couple of OK fine weather anchors out of there but they do tend to struggle when pushed. The size of the gear we supply Aussie is a lot smaller than the size of gear we supply the same boats in NZ.

Oh and I have test Equipment to 200 tonnes and that means what??? Not a lot unless numbers are put next to things

I want one to play with. Phone call going out now.

The little hump on the shank turns the anchor. Better than the big roll bars on some of the other newbies. I like the idea of a lighter aluminum and smaller sizing esp for 2nd. I'm going to get a price too.

Looks to me like the biggest anchor they offer is for boats up to 6.5 meters. That's less than 20 feet.

Yes, but look at the pics. Maybe, maybe not - I have asked.

personaly I think it's spooky as well that someone would design an ANCHOR that will come up with less up force needed. that defeats the whole purpose of an anchor.

Don't you just love reading some anchor makers claims and marketing speal. One would almost think most is written by some recently fired political spin doctor or someone a couple of beers short of a six pack.

They have the six pack, but missing the plastic thingy holding them all together.

First off I am an anchor idiot...

but..

I think you quoted what they are trying to do with this feature in a bit of unfair light.

They move the shank attachment forward so there is less moment arm while pulling the anchor vertically. That is to unbury the tip. Their contention is that with the shank at the normal location rearward more vertical pull is needed to overcome the longer arm of the buried tip.

Of course according to them the horizontal pull, which buries the anchor is unaffected by the "new' location of the shank.

Sounds good on paper - does it work? Elephino...

It doesn't look like I'd like my primary to look. Put it that way. Maybe a good mud hook. And like you said short scoping it would be problematic...

IMHO, it does not look anywhere near as good as the raya. Also the weights for the raya are nearer my own interpretation of anchor weight requirements, plus they actually look at the problem with a systems approach, quoting chain size, shackle size and rope size as a part of that system.

Yes but as everyone doesn't anchor at big scopes so do often get lifting forces. Surely an anchor designed to break free with lower lifting force can't be a good thing.

The video does not impress me. My size 9's will set to the ankles in short order if I stand at the surfline.
