Anchors - Bigger is Better ?

[Cotemar]

This is a new Convex/Concave anchor that I designed called Convave.
It is designed just for the few here that really like convex anchors, but still do not want to drag.
It has a self righting ASTM A514 = Bisplate 80 shank, as I know the convex guys do not like the roll bars. This one will be a deep diver.

The fluke is very strong, because of the unique W bend profile not seen in any other anchor designs.
The unique W bend profile fluke gives this anchor the largest surface area of any given size anchor.

This new Convave design is a hybrid Convex/Concave design that has a patent # US-willnotdrag , but I will gladly let you use my patent to keep your team safe in a 2am blow. You will sleep well with the Convave.

Congo, please feel free to make these for your friends Jonjo, Delfin and a few of the others on your convex anchor team. This Convave design will put money in your pocket for the next 20 years.

Jonjo, you like light anchors. Now worries for you with the Convave design. With the super strong and larger surface area of the W bend profile fluke you can just have Congo make this for you in Aluminum 6063-T6. Now you will have your non-rollbar deep diving light weight anchor. This anchor will be so good that you may need a few of them as they will dive so deep and hold so well that you may have to cut a few loose to go home.

Other than quite a few Problem Bends it might work.

But does Tern know you ripped off their design?

[Cotemar]

The Tern anchor is not even close to the Convave anchor design, but the Tern anchor does match Congo's convex designs along with Delta and Kobra perfectly.

Excellent design. I especially like how you spent the extra effort required to laser cut the logo. Some people might think the time, energy, and effort required to produce this is a waste that could be better spent making a better anchor or one that is cheaper to produce.

Not me, I am all about branding. Anything anybody can do to distinguish their product from all the others is all the better IMO. If it means incorporating your name into it so people people can tell the difference, so be it.

You might think the crabs could care less about a logo but that doesn't do you any good when you are hanging out at the dock showing off to your friends.

That said, your design could use a bottle opener for when you are hanging out at the dock. You know I heard they don't even give them to you when you buy an anchor, they make you pay. Is that true?

The Open Source Anchor has one built in. How's that for value added product!

I also like that Convave design.

Nice touch with those little drain holes in the fluke. Be sure and include a couple of bungs that can plug up those holes so that a when stowed on the bow roller the anchor can be filled with water and used as a bird bath.

It's actually not that bad. Folds reduce unsupported panel and mean you can use thinner material and still have the required stiffness, which means a bigger fluke. The Mantus does this and as such, like this design, avoids having a single peak pressure zone in-line with the shank as you see with any of the V-shaped concave anchors.

Someone, maybe Jonjo or Shas Cho, mentioned engineering earlier. Peter Bruce figured all this stuff out forty years ago. Some pay better attention than others.

Wow - I really like that Convave!

Since I need a new anchor and, quite frankly, have developed a splitting headache by reading these threads pro/con different new gen anchors, I'm opting for the Convave , as it splits the differences.

Please:
Would 250 Kilogram be the correct size for my 48 ft monohull?
What is the cost (in USD) for a 250 Kilogram Convave?
Would shipping to American Samoa be included in the price?
Are the "bird bath" plugs included, or are they optional?
Are they available in camouflage grey tones?
(So nobody can see it to steal it when I'm docked.)

Awaiting answers....

Perhaps you would consider the Open Source Anchor for your needs?

Not quite as fancy as the Convave but the design is free and it can be built anywhere in the world using simple tools and commonly available materials, which means you should not have a problem finding someone to make you one in American Samoa.

It comes with a bottle opener built into the shank which is handy and will feature multiple fluke styles for varied bottom conditions so you can enjoy the best of all worlds.

Having one made means you will make new friends and put money into the local economy wherever you are, not to mention you will save a bunch of cash which will mean you can stay out there cruising longer.

Just a thought....

You guy's are the best. LOL

Will have to add the Bottle opener and Bird bath plugs before I can give you a price for the 250 Kilogram anchor shipped to American Samoa.

No camouflage grey, as you will want all your dock buddies hanging out at your bow popping their beers open. DOCK PARTYYYY.

If the manufactures have control of these parameters why would they not select these test protocols to for their advantage?.

It seems a tad naive to think they would do otherwise, this of course applies to all manufacturers and diminishes the already low regard I have for the relevance of the current certification process (for our sized anchors).

At the end of day they still have to meet the (low) requirement for holding power, but it sounds like they are given considerable leeway.
I hope they are not permitted some choice with parameters such as to where the test takes place, and therefore can pick an appropriate substate where their anchor tests well.

Perhaps Rex would like to elaborate on how the testing locations are chosen?

Well noelex 77 my friend there are not to many places where one can test any more here in Vitoria, no less than 3 permits have to be issued, the bay that we tested in is not large but has a wide variety of bottom types, sand ,mud clay weed excetra, for the sand and shell test we had to locate to another bay, and yes long waits for the beurocrats to again issue permits.

T.A.T.S. STANDS FOR TIDAL ANCHOR TEST SKID, it operates on an incoming tide and follows out the outgoing tide, location is selected at low water, soil types are recorded and can change through the distance between high and low water, after soil testing is complete each area is marked of with stakes and tape to identify pervious soils types recorded, try doing this with a tug.

When Robertson turns up it is easy for them to confirm what we have recorded, and then starts the process, as you could imagine this is all very hard work and expensive.

One other thing should be notice all testing is strickly supervised by a officer of Robertson, these officers are rotated, over the testing time, I think it was three months we had three different individuals supervising.

noelex 77 I don’t see why you are interested, certification you made clear doesn’t cut it with you, so who cares?

Any way it looks like you have competition of your own, you will be finding it tough to get your posts in?

Regards Rex.

Hmmm, I'm looking at a Tern right now, and it looks an awful lot like your effort, problem bends and all. But whatever you say....

Of course you put up the videos, Rex.
Delfin merely provided a LINK to them.
You posted them to demonstrate things about your anchors
and I responded by asking a few questions about what I saw.
I was excited to have the opportunity
to speak with an anchor manufacturer
and thought I might learn something.
Instead, I was mocked, insulted, resisted
and basically told to piss off.

If I have offended,_disappointed you I sincerely apologize.

Of course you offended me.
I accept your apology
but I am astounded and confused by it.
You worked damned hard at offending me.
Not only were you rude TO me,
you made public and derogatory posts ABOUT me,
which is a thing I would never do to you.

I will learn from this and change the commentary.

You astound me yet again.
This doesn't sound like the same person
who responded to sincere questions
with defensive hostility.
Maybe you really CAN learn something.
Good on ya.

Further I will check my manners and see if I can improve.

I'll make three suggestions, if I may.
1- don't make claims that cannot be supported.
2- don't assume that anyone who asks a question,
nor even anyone who challenges your assertions,
is being hostile.
My background is in science
and I expect EVERY statement to be challenged.
When I have the answer, I provide it.
When I do not, I appreciate the heads-up.
and
3- don't talk ABOUT people.
It's incredibly rude.
Yell at me all you like,
but don't turn to the room in general and say,
"Look at what an ass Shas is."
They can see I'm an ass without your telling them,
but when you become the accuser
their sympathy for you evaporates.

I offer these suggestions, believe it or not, in genuine good will.
And as I said in my very first comment to you,
I'm impressed by the apparent holding power of your anchors.

BTW, I thought I would be back afloat almost immediately.
I learned today that the deal fell through
so I'm a dusty-footed land lubber.
Looks like I won't be buying ANY new anchors.

Take care, Rex.

Shouldn't that be Titanium,
for strength and to keep the cost up?
I won't believe in it unless it's expensive.
Also, could you please incorporate a water-activated strobe light
on the Cotemar C&C Deep Diver?
When I can no longer see the strobe
I will know the anchor is truly buried!

Good job!

And *ahem!* ...
This IS certificated, right?

OH, ah, ha, sure it's totally certified.
