I was thinking the same thing. I'd want to have tested the snot out of the thing, modded it and tested again. Used it a few times, then galvanize it after it was proven to be tweaked correctly.

And undersized anchors and old out-dated designs.

I do think I would have built a 2-pound version first, to check the angles and get it right the first time. I would test it on many bottoms with a load cell.

Re: My brand new Anchor, Home made,

An interesting thing about the Manson Rock Slot is that using it significantly effects the digging and burying angles (because the attachment point is now higher). The ability to penetrate a hard bottom is reduced, and holding capacity in soft bottoms is increased. The same thing is be true of any similar anchor that had multiple shackle holes, sort of like sail clew plates with multiple holes, and the effect on twist.

Yes, I have tested this premise with a load cell on two anchor designs.

Curious. A simple way to the adjust the angle of an anchor and subtly change its behavior. If the anchor is a good compromise, it's probably not worth the bother.

Re: My brand new Anchor, Home made,

I have seen a few failures of anchors not made with high tensile strength steel they ripped apart in dangerous situations which otherwise would have saved them

Re: My brand new Anchor, Home made,

Why do you believe that you can reinvent the wheel that has been studied by many organizations

Without a good engineering reason

Im up late , cant sleep , nothing else to do right now but read n write.
He ain't reinventing it . Hes got time on his hands and the knowledge and skills to build his own anchor. Not for profit , not for sale ! For his own use.
Incidentally, there are a lot of different designs of 'wheels', made from a lot of different materials.
If one does not like the status quo, no law states you need to adhere to it .
Different strokes, the beat of a different drum, what you got against that ?
Exercise a little less narrow-mindedness perhaps ?♐️⚓️☮️👍

I think you pegged it. He is only doing it for self satisfaction. Not a thing wrong with that.

MR B- does this mean your gem is finally fixed- I was so sorry to hear of the mess it became with the repairs...
They Have one floor back in, Both hulls have been replaced fully,
Its nearly there,

I can carry the anchor in one hand, So I dont think its heavy,
14 feet by 10 feet approx is the front of my Gemini,
So thats a lot of force in high winds,
My Gem wont be in a nice safe calm Marina when Im travelling,
It will be permanently on the pick when I stop any where,
And I will be single handing it,

Re: My brand new Anchor, Home made,

considering my new anchor dont fit in the hole in the bow that is there for the previous type anchors,
I had to make a new Bow sprit to take the new anchor,
The only way was over the front of the bow,
It also has to be on an angle to get past the Auto Furler drum for the Genoa Base cleat,
It also has a preset angle made into it to suit the slope of the bow that drops down towards the front of the bow,
I will have to go down to the boat to fit it before I drill holes to bolt it down,
The rear will be bolted down through the chain locker and have a plate under the fibreglass to spread the stress,
The front bolts will be a bit of a fiddle as they are deep within the hole that the old roller sat in,
Its made of stainless steel, Two lengths of 75 x 75 x 6 mm which I cut down to make the width narrower,
I cut the old frame in half and welded that on the front of it,
The V on the front is to stop the anchor flopping about,
The bolt in the middle is to lock it in place when travelling, It cant fall out,
I have a rubber strip under it to stop it rattling,
Old piece of conveyor belt,
