Doubt there is one specifically to take a Rocna, although it is quite possible that you can find one where it will fit the size anchor you have in mind. Rocna provide a scale drawing so that you can make a template to try on your bow roller arrangement so you can see if any mods are required, or what you need from a replacement. Google will get a wide range of off the shelf rollers. Be aware though you also need to consider the layout of your foredeck - for example many rollers project forward of the bow which may not suit your foredeck.

I purchased an off the shelf tilting bow roller for my rocna. Had to modify one of the rollers so that it held the anchor firmly when stowed. Can't remember details as it was 6 plus years ago.
Jimmy Green Marine might have a list of bow rollers to suit various anchors ?

It's a bit of a bugger because the anchor shank has such a defined curve in it so it doesn't really fit a bog standard one

Have a look here - Anchor Sheaves (rollers)
Maybe there is somebody nearer to home who could machine something similar?

That is only the roller. It is the geometry of the installed fitting that needs to be right.

Anchor sheaves looks like a great option thanks guys

The OP is focussed on a Vulcan, not a Rocna.
As Tranona says its not only the anchor that needs to fit but the new roller has to fit within the current bow arrangement of the OPs yacht.
I'm becoming repetitive, but I've been told that many times
- pictures are worth a thousand words.
If ts any help - the Rocna shank is a direct copy of a Delta shank, superimpose one on the other and you would not tell the difference. Do the same with a Sade shank, all sexy curves, and the Spade shank is a Delta shank simply re-drawn wth French curves - sort of smooth out the angles with flowing curves. There is little new in anchor design!

Sheaves (or rollers) are only part of the anchor roller. As Neeves suggests if you posted a photo of you current set up you will likely get suggestions as to what you need to do. If you have (as I suspect
) an older style boat it may well be that you do not have space to fit a roller that allows the anchor to stow and self launch. Based on the information you have provided so far all one can do is guess!rogerthebodger

I made a pattern of my proposed anchor from some hard board to see how it would fit on my bow roller
I then modify the pattern so i would fit and not damage the bow.
I the fabricated my anchor to the pattern

Your name is very wrong, it should be roger-the-doer or roger-I-can make that.

But the OP is not MAKING an anchor - his question is what sort of bow roller does he need to fit a specific Vulcan anchor.

I don’t know his skill set or his desires or finances but could he make the bow roller? Very satisfying especially if keeping the same boat for a while. Welding in stainless is not that difficult. Of course his circumstances may mean he needs one quickly and wants to buy one, I cannot help there.

Read the question - he is looking for "off the shelf". Impossible to make any sensible suggestions without see what the current anchor handling arrangements are.

Dear OP I don’t know if there is an off the shelf option. Other options would have to apply if that is so. Goodluck

If that is the style you are after, plenty similar available in the UK from makers such as Vetus, Lewmar, Ultra and most chandlers. No need to get one custom made which will cost far more than an off the shelf one

My bowroller. Tilting type and off the shelf, possibly from Force 4 chandlery. I had to modify the top roller by purchasing some nylon bar and drilling a hole through the middle. Grips the anchor quite well but I still tie it down. The two bottm rollers are grooved to hold rope or chain centrally.
