    Hello All,

    A friend of mine is in a part of the world where many mass produced consurmer goods are not readily available. So, he wants to have the local smiths fabricate him a 25kg anchor. Does anyone have a set of patterns / plans / technical drawings suitable for one-off manufacture of a Delta or Bugel?

    All the best,

    John Caprani

    Here in Alaska many fishermen "knock off" an anchor and frequently make the Northill style. I do'nt think the dimensions, angles and such are very critical and I suspect that most anchors are sensitive to slight changes but I have a Northill that is a good forged anchor and could provide the fluke angle for your friend. Here is an example of a rather large one in Petersburg.

    Note that the B├╝gel Anker is patent protected.

    A question about patents:

    If you are making something for yourself, is there ever a legal ramification to copying a patented design?

    As in, say I made an anchor from the Rocna. Say I didn't sell this anchor, but used it on my own boat and only made one. Would that be an issue?

    Same question, but with Chris White's foil mast...?

    " ... he wants to have the local smiths fabricate him a 25kg anchor.... "

    that sounds to me like looking for a commercial copy of a patented design

    Maybe. I wasn't asking to defend the guy. I was curious for my own use. I was thinking of copying a Rocna anchor and doing it at a local machine shop.

    Rovna anchors web site tells all the countries that honor their patent and asks everybody if they see a copy to contact them. I would make a few changes if I was to build one like theirs.

    My understanding is that making an object with a feature which is covered by a patent is a violation of the patent, irregardless of whether the make will use the object themselves or sell it.

    Don't see the problem as long as you are not manufacturing to sell. I.E you are not in commercial competition with the designer. Technically I guess you are violating a patent but who in their right mind is going to go thru the expense of taking court action for one personal anchor. If that were the case, there would have been a continious court battle with Japan in the 60's and 70's and more so with todays Chinese manufacturing counterfitting just about everything. You can make one for yourself or wait until next week and buy one made in China for 1/4 the going price for the genuine article. Sad but true, a merchant knows no borders and has no conscience.

    If I do make one, it surely will be from quality, galvanized steel. I think you'd have to hot dip one. Haven't researched this yet.

    Would never buy a Chinese anchor.

    Making things yourself (as you know as a person building a boat) gives you a much higher quality product for a reasonable price.

    Check the local scrap metal yard--you might be luckey enough to get enough stainless to manufacture one. When you calculate in the cost of hot dip galvanizing(zinc) the cost might work out to be the same with the added feature less running around to have it done plus stick welding stainless is such a pleasure to do.

    Stainless is no good for an anchor for me. I'm on it 24/7/365, so it is prone to oxygen starvation. I can only used galvanized anchors and chain.

    Doesn't sound like anyone has what you're after John. Perhaps the manufacturer would sell you plans at a reasonable price if you agree to a one-only contract.

    from BigCat webside, only two pieces of flat-iron....

    http://bigcatcatamarans.com/

    towards the bottom of the long page.

    Could anyone tell what his '
    different approach to turning the anchor over on the when it's upside down


    is? I see pic 1, then pic 2, with nothing in between.


    I don't know anything about anchors, but I'd bet the pros actually forced themselves to make anchors of various angles and went out to test and test again.


    I sure wouldn't sweat patient infringement on an anchor, as they are all tweaks of same idea. I think you could take your best shot at making a copy, and still have the case thrown out, just because you ain't that good. Make a big grid on a big piece of paper and hold it behind your anchor of choice for top, side, right side pics and email him the pics.

    If it works really well, take some better pics of what he actually built and send those to the one you TRIED to copy with notes on what bottoms it was working good on...just for karma.
