    Surprised I did not find plans to make a Sandford/Fortress style anchor for sandy bottom.
    $hipping one overseas would be like sending an... anchor !
    With plenty of welders and metal leftovers overseas, would like to send drawings to my nephew. Do you know of a website to find such ?

    Closest I could find was for a Danforth, looks like it's older steel cousin to a fortress. The first link has the diagram and the second are the dimentions for the various sizes. As far as I can see, the Fortress is a lightweight aluminum version of the Danforth.

    I may have a small Fortress in my anchor pile, I'll check tomorrow, but if it is the one I remember it's quite small, and I don't know if the measurements will help you.

    Good luck on your quest.

    The second link has the dimensions, you have to look around a bit, not user friendly. Sorry about the mixup.

    I checked on the baby anchor and it was a Danforth, maybe 5#. I did run across a 50#, or in that range, Danforth if that is more the size you are looking for, I could take pictures and measurements. It's a brute, and I wouldn't want to pull it by hand.

    Rereading this, I had a flashback and a chuckle. I can't help myself, I have to share.

    Years ago I found it on the bottom in 50 feet, or so, of water off the NorCal coast. With my BC full I had to kick like hell with both hands holding the anchor to break the surface, where I found my friend in the inflatable looking the other way. I couldn't keep my head out of the water long, and if I used a hand to put the reg back in my mouth I'd lose the anchor, so I dropped back down a few feet and tried again. On the third try I knew I couldn't hold it any longer so I spit out the reg and yelled for him to grab the anchor. He was startled, but was listening, we got it aboard, having him put it on a seat figuring it would go through the bottom.

    So I did pull it by hand, and it was a brute. The comment was not conjecture as I thought when typing.

    Not only would I say don't try this at home, I'd never try it again and now usually carry a lift bag and some rope, just in case. And if one does, make sure the man in the boat has a head on his shoulders.

    Another day under the ocean.
