Has anyone tried a 20kg Vulcan or Rocna on a 385?

Hi Mark / Catherine
I have a 20 kg Rocna on my 430 made it myself wieghs 25 kg actually , Brillient Fantastic
If you go on line you can find drawings for the full range of Rocna anchors.
I'm sure there not there so we can all start making our own, but I could never bring myself to pay there £600 plus

Hi Mark & Catherine,
After 5 years I lost faith in my 16kg Delta. In the week before Christmas I installed a Sarca Excel 22kg (an Australian brand in the league of Rocna & Manson). The 22kg model was the recommended model for the size & weight of the 385. I took my yacht to Sydney for the New Year period. The Sarca set first time each time even in 15m of water & a mud bottom in Athol Bay, Sydney Harbour on New Year's Eve.
Naturally I had to extend the bow roller fitting. I extended it 200mm and, for the first time, my anchor is clear of the bow at all times.

Have you tried your Sarca Excel in weed yet? I usually find thatís the toughest test. Our Delta is perfect in sand & mud.

Hi Nigel,

Understand that weed is always a challenge with any anchor, but where we operate weed is not normally a major problem but remember I only fitted this anchor a few weeks ago so it is early days yet. And we had a southerly change on New Year's Day in Sydney Harbour and, again, this anchor held fast where the Delta had failed me dramatically in the past.
I have a copy of independent testing of a range of anchors in various conditions. Happy to share it if you would like to send me your email address.
Regards, Mike

I carry one of these for high weed areas. A Marsh Stockless. Namely Tasmania and South Australia. The Sarca is a good anchor. I would love to know how you extended the bow MikeB.

Templates were made for the side-plates & the chain slide plate extension & these were used by the laser cutter to cut the plates. The 2 side-plates & chain slide plate extension were fully tig welded. I inserted a bolt with back nuts at each side plate at the original location of the roller for extra stiffness but that was not really necessary.

Got it. That is very interesting and great work! Is the extra weight noticeable at all, and is it harder to reach the pin?

Yes. The extra weight is noticeable. It is a significant weight increase & you are lifting it a further 200mm out. But the most significant thing is that you are releasing an anchor that has actually dug in & doing its' job like you haven't experienced before.
Re reaching the pin, the pin never worked from day one when the yacht was new because the hole in the Delta anchor did not align. For the first time I now have a pin that actually secures the anchor. Sure, it is a reach but it is worth the reach.
Best Regards, Mike

Hi Mike

Thanks. Iíd be interested in receiving the anchor test results. Nice work on your anchor changes.

Hi Nigel,
Below is some independent test results on anchors. I have been reading everything I could  find on anchors for the past 2 years & Cruising Helmsman has also published many good articles on the subject. The one rider is that there is no perfect anchor for every situation one might encounter. I also had a number of conversations with Rex Francis of Anchor Right who design & manufacture the Sarca anchors. I already have the thumbs up from the Admiral after this short time. Regular multiple anchoring attempts does not do anything for good relations with the Admiral on the yacht.
Best Regards, Mike

Hi Mike,

Can I ask how much chain you have? I am about to increase my chain from 30 to 60 metres and replace the Delta 16kg with a Rocna 20kg. This is for an east coast trip this winter. Interested in your opinion.

Cheers

Hi Steve, My yacht, "Elara" came with 30m chain & 20m of rope. Not enough for Sydney Harbour at New Year or some parts of the Hawkesbury River area that I frequent. As part of my anchor upgrade I have added another 30+m of chain so now have 60+m of chain & 20m of rope. You are making the right decisions for your trip so that you can sleep well no matter what the conditions. But you still need to be careful once you get into the Whitsundays where you may be anchoring in coral debris on the shores of some of the islands. Enjoy your trip.
Best Regards, Mike

Hi Mark and Catherine. I know this is an old thread but I installed a 20kg Rocna on my 385 earlier in the year prior to a cruise on the Australian east coast(ongoing). Iím very impressed with the holding power of the anchor and can recommend it for the 385. It fits without modification to the bow roller fitting. A slight modification to the roller allows
the pin to fit in front of the anchor to hold it securely. I also installed 60m of 8mm G4 chain and havenít noticed any weight issue. I can provide photographs and further details if itís of further interest.

Hi All,

We used the Delta on Breathe for the first time last week. The anchorage was a well known location where the CQR on our old boat set first time every time. It took three attempts for the Delta to set with the anchor dragging when applying engine reverse to dig it in.

We eventually got it to set by using a very low level of engine power, and building power slowly, but did not have a lot of confidence in the amout of grip available.

Is that a typical experience with the Delta?

Thanks
Gordon

Hi Gordon
 The way you describe is the way we have set the anchor from Port Phillip and around N.E.Tasmania and up to Cairns. Gently reverse and gradually increase power.
We still just use the 16 kg Delta that came with the boat. It has been adequate, but that is all. They are a basic middle performing anchor that at 16 kilos is at the lower end for a boat set up with sprayhoods and other wind catching gear. I stuck with mine because of it fitting into the bowsprit. Once set I haven't had a problem except on really bad ground.
My spare is a weed and rock specialist anchor, but I will definitely get something like the rocna described above when we go on our next extended cruise for  a primary anchor.

my problem with the rocna is that it looks like the hoop will foul the furling drum on my furlstrom gennaker, do you use a furlstrom Steve?

Hi I am looking at a Rocna 20kg for my 385, as next season weíre circumnavigating British Isles. Experience over the last three years is the Delta is ok in sand or mud, but any forage present and it simply slides.
If you have pics you can share that would be much appreciated, donít really want to modify the bow too much, but small amount quite acceptable.
Interested to hear from anyone regarding the Rocna hoop fowling the furling gear of a Genacker.

We have had good luck over the past year with our Mantus 35 pound stainless anchor. It fits well and never has slipped on us. Their swivel is also really good and heavy duty. I think Mantus is a great company with innovative products and everything is very high quality. Where we sail the bottom is pretty soft and muddy, so I cannot say how it would do in other situations.

Is the 15kg size sufficient for the 385, as itís at the max for the size of boat. Just wondered if you have ever wished youíd gone for a 20kg?

We have had no problem using the 35 pound Mantus, although I have not tried it in anything approaching storm conditions. The next size up was 45 pounds and I did not think it would fit on the bow roller without modifications. I carry an extra Fortress anchor on board, and I think if I ever needed more holding power I would deploy the second anchor also.

Hi,, would it be possible to see a picture of the anchor on the bow roller, and what small mod did you carry out to retain the anchor? I am looking at the Rocna 20Kg but donít want to have to perform any drastic changes.
Thanks.

Here are a few pictures. The only modification I had to do was rasp about 1mm off the small pin that is on the rod that goes through the anchor. There is still plenty of the pin left to keep the rod from sliding out. The pictures of the Mantus swivel are on the old anchor, but it fits the same and allows the anchor locker hatch to close with about 1mm to spare. As much as the next size anchor would be nice, this one fits well and has performed well. And I like that their stainless steel anchor has a somewhat dull finish that does not show dirt or wear.

Thanks for this. I have just been sold a 20kg by Jimmy Green Marine in UK, they said it was their best seller and strongly recommend. They have also said they will exchange for the Mantus if it does not fit as I wish, so I have a few months to play around until Iím likely to drop it in the water. I know itís sales pitch, but as far as I can see the rollbar type all pretty much work the same, pay your money take your choice. Iíll post a picture once Iíve finished faffing. Thanks again. Adrian.
