D or bow shaped shackle to connect chain to anchor

[tudorsailor]

Is there a preference for the shape of shackle to connect my anchor chain to my Rocna? Does allow the anchor to sort itself out on the bow roller better than the other

Thanks

I use Bow for better articulation

I use D for width constraints.

I use a bow, pin through the anchor, to minimise snagging of the pin on the bow roller when hoisting.

D but will be going to D, 3 links chain, swivel, main chain having just read a great article by Vxy Cox in an
old YM. That is: Fattest possible galvanised D shackle connecting the anchor to 3 links of chain,which are connected to an oversized swivel,which is connected to the main chain.
When I can afford a swivel that is,cheers Jerry.edit actually the stainless ones tbe chandlers sell are suspiciously cheap!

The water that I sail in is so "thin" that I don't need a swivel.
Actually, what I do have is a short length of galvanised steel bar with an eye on each end, which has a bend in it of about150°. As soon as this bent link comes onto the bow roller, it immediately turns the anchor round the right way. Works perfectly every time.

The only swivel I would trust is a Kong.

Hope that whatever you choose, its certified as breaking strain etc.

Seems a lot of money to throw over side without ensuring 'shakle' is best there is!

I am planning to buy a Wichard Shackle made of High Resistance Steel with a SWL and Breaking strain that is greater than that of my certified 12mm chain as seen at http://www.s3i.co.uk/high-resistance-stainless-steel-bow-shackle-12mm.html (cannot seem to make a hotlink)

I thought bow shackle was short for the full name: bow type anchor shackle. In other words bow instead of D on an anchor?

Bow shackles are slightly weaker than "D" shackles of the same size.

Tudor sailor, I note you are using 12mm chain, what size is the yacht? If one is to go to the effort of buying a really good shackle - it only makes sense if you have a really good chain. Could never understand the need for a swivel, unless you are to leave your yacht for days, many, and it will continuously turn, as in a tidal anchorage. Given the 'weakness' of swivels and the addition of 2 extra connecting points it must be safer just to drop the chain, or some if it, in deep water to allow the chain to untwist (but you do need a decent windlass).

I have 49 foot 20 ton yacht. I do not anchor for more than a day or two at a time, and this in the Med, so not tidal

I am not asking about swivels, but simply the choice between D and bow shaped and the reasons

Thanks

Sorry, someone else mentioned swivels. I'm guilty of perpetuating thread drift! We are currently using a bow shaped shackle. We have used rigging toggles, without any problems.

But we do change anchors regularly so are constantly monitoring the 'connectors'.

Your season is just starting, enjoy the balmy weather.

No worries!

I have now plumped for a Wichard Bow shackle made of High Resistance 17.4 Stainless here. So thanks for all the advice
