New Generation Anchor Dimensions

Help! Us low-rent third-world losers over on the open source anchor thread are trying to design a low-tech new generation anchor so that you don't have to worry about us dragging down on you in the middle of the night with our rusty plow anchors.

We need some dimensions of materials thickness used in new generation anchors in the 20kg/44lb class. Apparently we're so destitute that none of us even has physical access to any of these anchors because we can't get any answers on our thread.

It would be most appreciated if you would be so charitable as to take a look at your anchors with a tape measure and give us some dimensions. Inches or metric, we can work with both. Doesn't have to be exact, just as close as you can get.

Specifically we are interested to know what the thickness of your flukes are between the tip and the shank, as well as the thickness towards the outside and behind the shank. On some it might be uniform, on others it may vary.

We need this information so we can get in the ballpark of what the structural requirements are and start to design our fluke(s). The more different brands of anchor we can get data from the better, so don't be shy.

Also, if your shank is cut from a flat plate, it would be great if we could get that thickness too. If you have a spade-type with a hollow shank that doesn't do us any good but we will still be grateful for the fluke dimensions.

Thank you!

Unfortunately I have tried those sources, they only give the geometry as it relates to whether or not it's going to fit on your bow roller. We are looking specifically for material thicknesses used in the fluke and the shank, generally not given in manufacturers dimensions.

Thanks for your input though, we need all the help we can get!

Re: New Generation Anchor Dimensions

Galvanized Manson Supreme 45 pound.

Shank = 5/8 inches
Fluke = 21/64 inches
Fluke at tip = 43/64 inches

Looks like the tip is a two layer sandwich of the same material. The extra 1/64 inch must be a small gap between layers.

Sorry for the US measurements - I am just a damn Yankee.

This is exactly the kind of info we are looking for. From as many different brands as possible. Awesome. Thank you!
