I was chased out of my mooring due to dredging works and had to move upstream by a mile or so.I've had the boat at anchor since but don't want to lose the spot because there are many yachts coming in and there's not a lot of mooring space.So I made this little 20kg thingie.Ordered the steel on Monday morning and picked the anchor up from spray galvanizing (sorry zinc sprqying) an hour ago.Tomorrow I'm off to Ayamonte for some cheap galvanized 10mm chain and on Saturday there'll be a brand new mooring in place.Mind you it wasn't pleasing work.We had 40º in the shade yesterday...

There is no such thing as "spray galvanizing"
There is genuine galvanizing, (Immersion in molten zinc forming an alloy coating)
and zinc spraying (throwing molten zinc at a cold steel surface hoping some of it sticks)
and electroplating (deposit of pure zinc from a solution, driven by electricity)
and painting (using a zinc rich paint)

I know that...Thanks for the correction! FYI it stcks rather well and stands up to the marine environment much better than would be expected.

Nice job, but are you sure you got the balance right? The shank looks rather heavy compared to the flukes. Do let us know how well it sets.

If it does work well, give it a fancy name (perhaps the "Samson Sea Bream" or something like that) and make a website dissing all other anchor designs, then rake in the profits :)

That is a definite non-bending piece of marine sculpture :)


I really only can naturally admire it.....

I hope it will work very well.The proportions are the same as on the real thing and I already have a 15kg that sets beautifully and holds like nothing else.

Looks good, hope it works well; it will be easy to add a balance at the tip if need. Make one more, give it a name and put for sale on e-bay; you never know, you may be in business.

That's an ingenious and original design. I would get a patent and move to Brazil, but keep offices in NZ just in case...

You could call it a "Sling Your Hook" (SYH) and make a mint. I would buy one if shipping costs were reasonable...great work.

Months in the drawing board you know...:)

Good idea, years ago when I posted on my first copy I was threatened by Craig of Rocna with court action.I told him to go ahead and have a ball!

I'm very happy to report that the anchor works to perfection. It set very quickly and when I dived to check it was completely buried in the hard sand bottom. I'm chuffed to bits.

On the contrary - bending the shank is an inherent weakness of all the concave roll-bar anchors - to the extent that nearly all of them have modified the design to a high-tensile one.

there's no way that shank is going to bend. Look at the webs top and bottom !


The only feature I would add is another hole where the shank turns down, for an anchor marker line.

Yes I thought of that too but then why not tie a line to the roll bar?

I'm reminded of the statement on every copy of the Rosslyn Park rugby club newsletter...
