Hi Bonaparte, thanks for sharing, including the cutting file . . . ​

This is not final cutting file. I have to make some more changes. I will finish the project in one or two months.
Newt week i am planing to make 20cm small diferent metal models to test it. To see what is works and what do not works.

 

[Bonaparte]

I paid $20 for a 22 pound, used Danforth, and it works great

Danforth is good anchor.

On a sunny day everything works great. Sometimes is you can put only the chain in the water without anchor and the boat will be fixed.

Danforth vs nev style anchor:

I want to make new style anchor for extreme weather. When is outside huricane that I am inside and playing chess with my friend and do not give a **** for weather.

BTW, it looks like a welded version of a Mantus anchor, but with the aft end going up, like on the Original Rocna and also like on the Rocna Vulcan . . .

Yes, heel it works like breaking sistem.
Or other good anchors like Super Sarca

Bonaparte,

Applaud your effort and it looks like a good design if the stock is beefed up AND you have the correct angle, maybe its just manufacturers saying this but have heard even 2 degree off can be a disaster.

You say $100 dollars for materials which sounds right, figure another $100 for a welder yes , from your profile pic it seems you can do that but most people cant. Then you prolly have a $100 dollars to galvanize (have heard because of the hazards and regulations only grandfathered shops still do that) .

Area im from is one of the steel capitals in America and to go pickup steel, cut it yourself, take it to a welder, drive 70 miles for galvanizing, then pick it up would add up in fuel as well as very time consuming.

So in the end costs are very comparable and if you value your time then its even more exspensive.

As a matter of fact just ystdy i was going to plop the 450 for the 22kg (48lb) rocna as I ve been manufacturing all kinds of other parts which is getting tiring and an anchor manufacture would be inefficient time wise.

Of course if you find pleasure in such an endeavor, go for it.

material + cutting + welder + galvanize = fabric price 100$

Original anchor same size (25kg) cost 1.000$
And I belive that mine is beter that other anchors because have all good thing from four diferent anchors.

I am from Slovenia - EU. We have cheep production cost.

Bonaparte,

have heard even 2 degree off can be a disaster.

You are right.

There are small diference between anchors in degree and big diference in efect. I am studing anchors for a mounths.

I was spaking with Jože Mušič who is designer of sidro Rocna.
The ring is better that is made from wide tube. For 25kg anchor ring must be made by Φ40mm tube. The ring is not only for turning anchor in right position but it is also works like a break.
Other anchors have ring made from thin tube Φ21mm.

the new design for shank is curved like on Rocna Vulcan or other anchors. To turn achor always right when is lifting up. So you do not need to buy accessories.

This concept seems as a modern vertion of the old chinese anchors. They used just a piece of metal for economy and some light wood to make it catch the bottom at the right angle. The idea was to use less metal, expensive at the time, and great grip power.

The anchor was made entirely of wood, the only metal being on the single fluke.The stock is placed at the end of the anchor, next to the fluke, and not at the cable end. As soon as the anchor strikes the bottom, the weight of the metal fluke brings it down, and as soon as it takes hold, the stock lies flush with the bottom, and makes an anti-fouling anchor.

On what kind of bottoms did you use the 22 pound Danforth yet, and on what size boat was that, and in which wind and wave conditions . . . ?

Sand/mud/gravel 6:1 scope, 35 knots of wind, 25' houseboat, 3 - 5 foot waves.

Hi BlueBell, thanks for the info . .

Recently I've came across the below picture of DIY anchors . . .​

Sylfia ---> Build​

The boat is L 23 m × B 5.4 m × D 1.8 m - got the specs from a sales ad.​

( above pic is 1,600 × 1,200 pix, here's a 4,000 × 3,000 pix version )​

P.S. - Bernard Kuczera, the owner and builder of Sylfia, sadly went missing at sea, but this is not the guy pictured with the anchors.

In May 2011 Bernard’s dinghy was found 12 miles off the coast off from the Bay of Islands. Hundreds of people from the sailing community took part in an extensive sea search, although Bernard Kuczera, the larger-than-life “master mariner” was never found. He now rests in one of the most beautiful sailing grounds a sailor could ask for.

This is last design of my anchor:

I made six diferent samll anchors and test it in sand an mud. I tested all modifications.
There are videos of test:

The anchor work amazing.
The Storm anchor is beter than original Mantus for 40%.
