Considering upgrading our ground tackle on our 34. Leaning towards a Rocna 33 or 44#. Has anyone else out there put one a 34 bow roller. Interested on how it sits on roller and clearance from blade tip to topsides.
Thanks,

We have a Rocna 25 on our PS40. The anchor has worked well, and we've had no problems. My main concern is that it doesn't readily allow having our CQR 45 in tandem on the bow.
You might want to check to see if the retaining pin on your anchor roller will fit the Rocna.

Don't worry too much about the retaining hole locations. I carry a 44 lb Bruce and a 35 lb Delta on the bow of my 34'. The retaining holes were not correctly located for either anchor. A couple of hours work fixed both.

I went to the junk yard and found a piece of 1/8" thick by 1-1/2" wide stainless steel flat that I suspect is 304. From McMaster-Carr, I bought a piece of 7/16" stainless round, some large split rings, and some safety pins. At Lowes I bought four short 1/2" bolts and nuts.

At the boat I measured the distances from the bolt that serves as the axel of the roller to the existing retaining pin hole and the distance from that hole to the hole in the anchor. In the case of both the port and starboard anchors the three holes were arranged in a straight line.

At home I marked the three 1/2" hole locations on the stainless flat and struck 1-1/2" diameter arcs around the first and third holes. Then I drilled the holes, cut off the piece with a hack saw, and ground the ends round. After I had made all four pieces (two port and two starboard), I polished then up on a buffing wheel.

The next time I got to the boat, I bolted the four parts I made to the bow; the lowest hole in each piece to the bolt that passes through the roller and the second hole to the existing retaining pin hole. I stuck the stainless rod through the topmost holes in each pair passing through the hole in the anchor between and marked the required length of the two retaining pins. I cut the rod to lenght then drilled a 5/32" hole through one end for the retaining ring and another through the other end for the safety pin.

I now have two oversized anchors nicely pinned to the bow of the boat.

I would love to see a picture of that.

Bill, I would love to se a picture of your anchor mount.

I have a picture of a Rocna on my 34, but it is currently just tied in place with a piece of rope until I figure out a permanent mount. I think I have a picture attached.

John,
Thanks for posting the pics. I wanted to see how it sits on the bow roller. Looks like a nice fit and the pin location can maybe be drilled into the anchor stock to retain it. Looks like no room for a 2nd anchor as Paul indicated above.

Thanks,

I have a 60# Manson Supreme (Rocna knock-off) on my 37 - and do I sleep well at night! :) Works beautifully. No way could I also fit a CQR on the bow at the same time - but I'm really not sure why I'd want to anyway.

The Manson fits in the roller well but the retaining pin was never a good fit for the old CQR and indeed isn't for the Manson. I manage keeping the MS in place by tieing a line around the roll bar of the Manson and securing it to the Pulpit. It's quick and easy to tie and to undo and very secure. It also is used to tie the anchor upside down on the roller when on the mooring - to prevent chafing the mooring line.

The Anchor gets lots of comments and is one of the best upgrades I made to the boat!

John,

Have you found the Rocna 15 to be adequately sized for your boat?

adequately sized for my PNW cruising grounds

John, I have found it more than adequate for my PNW cruising, whick admittedly has not stressed it. I spend a lot of time at anchor in the summers, but the conditions are usually mild. It is certainly more adequate than the 33# CQR it replaced and it grabs wonderfully. For a storm anchor, I would go up a size, but I'm not an expert on this. I had considered the l;arger size when I bought it, but the Rocna staff convinced me that the 15 had more than adequate holding power for my boat.

I have a Rocna 15 (33#) on my boat, and it fits the bow roller just fine. :) Don't have a photo of it at the moment, but will post one when I can later this week. I think the Rocna 20 (44#) would be a bit over kill for your boat.

Here are two pictures of my efforts to extend the retaining pin holes on the bow anchor roller of my PSC34. One is of the plates that extend the holes for the 44 lb Bruce. The other is of the retaining pin (the spare, I made three). I'm sorry that the stainless is a bit rusty and that the teak is unvarnished, but every time we start to do something cosmetic, we just go sailing instead. Right now we are anchored in Miami on our way to the Bahamas having left New Bern, NC in late January.

Very nice Bill. That doesn't look too hard to accomplish.

Does anyone have photos of the Rocna on an extended sprit/anchor platform such as is found standard on the PSC 31 and 40, and optionally on the 34/37?

P.S. Johnharch and SD, thanks for the feedback on the Rocna sizing. Much appreciated.

Bill,
Nice retrofit idea. I believe thats gonna work on our bow roller arrangement as opposed to drilling a new hole in the anchor. Ordered a model 15 (33#)Rocna today from our West Marine. I'm getting it for my wife's anniversary gift! (her idea)
The folks at Sun Coast Marine (Rocna dealer) verified that the 33# would be more than adequate for our 34 and thought the next size up would be overkill.

I'd also like to see if anyone installed these on a 31. I bought a 15Kg Manson Supreme from Defender last year and had to ship it back because I couldn't figure out how to make it fit the bow.

We have installed and deployed our new Rocna 15 anchor. Sits nicely on the bow roller and deploys nice and clean when releasing the brake on the windless. So far we are pleased. Opted to lash it to the bow platform as opposed to drilling another hole in shank. Rocna does not reccomend using pin as they claim it could bend and jam if dunking anchor in a seaway. Thanks for all the feedback.

Re the requests for pics on installations with projections ('sprits and the like), plus more info along the lines of Norstar's comment above, please do reference the Rocna Knowledge Base at:
www.rocna.com/kb

Under "Anchors", specifically those articles under "Bow roller compatibility".
