Rocna Anchor on a 75

[GCSI]

I’m about to order a 55KG (121 lb) Rocna for my 75CMY. Does anyone know if the Rocna will play nice with my pulpit?

You might want to consider the Vulcan made by Rocna....

I believe the fit of the Vulcan would be better than the original Rocna…

I'm looking at the Vulcan 55 kg myself ...

I have the 55kg Rocna Vulcan and it fits well, if a bit low. I had to cut a notch in the front of the chrome steel to allow the anchor to come up a bit more. The shank of the Vulcan is very large and gets stopped from coming full up by jamming between the roller and the front of the steel pulpit assembly. A notch a bit wider than the thickness of the shank lets it come up several more inches.

I’d post a picture, but I used a hand grinder and it’s a bit of a hack job. I plan on making it pretty this fall when we haul out. Mr Clarkson’s pictures have made me embarrassed to post pictures of my ugly duckling!

Michael... I woud much appreciate a photo so I can more easily visualize how the anchor fits under the pulpit.... when I looked at the Vulcan shank dimensions... I did wonder if the bow roller frame would need modifying..... did you think or try to move the roller aft and drill new holes for the roller shaft?

I was thinking that might be a possibility....

If you could even PM me the photo it would be most appreciated.... Thanks!

I thought it would be harder to drill SS than to grind it. If we were in a shipyard or on the hard, I would’ve tried to relocate the anchor roller instead. I’ll be anchoring near Deltaville later today and will try to get a picture to send you.

Much appreciated!!

Hi,I use a 55kg Rocna on my 54MY. It sits perfectly in the original pulpit, no modifications done. See pic

This is the notch in my pulpit. I’ll smooth and fill the fiberglass during the fall work program. This was a quick and dirty job to make things useable.

You can drill stainless steel but you need to go slow. Slowest speed your drill will turn. Lots of lubrication to prevent it from getting hot and "work-hardening" at which point you're pretty much screwed. If drilling by hand, use a carbide tipped bit. Don't use solid carbide or you'll break the bit every time.

Thanks Michael... IMO... that's not such a horrible fix....

Not the same anchor, but to get a fit for a 110# SuperMax on a 63 MY, I made the "ears" to drop the
roller about 4 inches. They bolt in to the original roller bolt holes. Pictured is my prototype; will have SS model made this winter.

I am thinking about this "upgrade" as well. can anyone who has made this fit speak to the set and hold of the Vulcan? Does it work well as an anchor?

 

[Westfield 11]

I have a 55kg Vulcan on our 63’ CPMY and it fits and works well. I had to notch the plate at the forward end of the pulpit opening to get it to fully come up to the windlass. You could also reposition the roller to accomplish the same thing, but it was easier for me to grind SS than to drill it. It sets easily and holds well, the highest winds, so far, have been in the mid 40’s (mph) in sand.

 

[JD5652]

I installed the 55 kg Vulcan on my 58LRC this spring. First time out this spring we had 35-45 knot winds for about an 18 hour period and she held like a champ!

The anchor set on first drop as well. Giving it another workout this weekend for the July 4th holiday.

JD, did you have to modify the bow pulpit or roller, etc to fit that anchor? I will need to replace a 65# (undersized) CQR on a 58LRC also.

Thanks

Water works better than lubricant. I know it sounds weird but it’s true. Slow and wet and it cuts faster.

 

[JD5652]

Zig-

Yes.. I had to make the same notch as Westfield. I used a cutting wheel and it went pretty quickly. I made several cuts and notched them out.
