    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.

    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.
    [​IMG] 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.

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

    Sylfia ---> Build

    [​IMG]

    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.
