Rocna anchors


Recommended Posts

Been a plough man all my years with out any issues , but with a furler and fitting a anchor winch I see the plough will damage on its way over the deck , I watched a rocna winch home very neat up over the paw under the furler and with no effort , will be wanting 10 kg size , any issues found with these , seam very light compared to the plough,

There is a large amount of all purpose fixed shank anchors.

In essence you can divide them up into two groups. (Not including Danforth or Bruce for good reason)

The flukes go up, and the flukes go down.

Most of them have similar shank lengths and angles, compared with an old school CQR or plough anchor which has a longer shank, and that annoying floppy bit.

 

There is so much "information" about anchors.....

They are crap if the boat has dragged....and amazing if the boat has survived a severe blow...

A million variations and permutations....(including personal pride and prejudice and a need to sell the product) are involved.

 

Of the above mentioned group, claims of vastly different performance between them is simply not founded in reasonable science or proof (unless they simply break or bend).

 

There is a small amount of physics that says that the flukes go up type, have slightly more burying and therefore resetting ability compared to the flukes go down (plough head shape) In sea bottom that an anchor will actually bury in....

 

These are the Rocna and manson supreme plus a few others and now a great many well built home versions.

 

The flukes go down are the Sarca and delta type plus a few others and a great many well built home versions.

 

Even within the well known , most vocal, brand names, there has been variation in manufacturing and material specifications...

 

All things being equal, science dictates that a smaller , lighter anchor cannot hold better than a heavy, larger one.

So...given that most fixed shank anchors will probably sit and set better than a CQR on your bow and bottom...

...that 'as big as can be safely managed and stowed"...

Dont be to worried about your choice...

All things being equal, science dictates that a smaller , lighter anchor cannot hold better than a heavy, larger one when talking equal design and construction materials are used.

 

If you are dead set on a rocna buy a shovel. Same design with 2 small improvements, constructed with same materials, same country of manufacture, 1/2 the price.

Interesting, the current "Boating and Outdoors" catalogue says the Shovel is "NZ Made", has Rocna returned to NZ manufacture?

Excel.

I’m on my 3rd.

Best option in NZ.

 

 

I'd listen to Km on anchors all day long+.

Love my Excel.

 

Just  not so much on conservation.....haha!

I can't speak highly enough of my Excel.

I make sure the kids are sitting down now before backing down on the Excel. Like backing into a brick wall. It sets and stays set.

 

PS, I had a plough / CQR, was never sure if it set. I'll find my test photos.

Photos kind of say it all really. Arkles Bay at low tide. Similar bottom to lots of spots around where I am in the Gulf.

I towed the plough up and down the beach in a figure 8. Didn't matter what I did, I couldn't get it to set.

Yes,in addition to all his wisdom on worldly matters. I'd like to hear your take on the best anchor for our waters KM. You'd no doubt see and hear it all.

We do see a fair bit, the good the bad and too often the ugly.

 

The best anchor for the Hauraki Gulf or further afield is the one that you find easy to set and allows you to be confident to slip into a rum induced simulated coma and wake up in the same place. There is no one best anchor, anyone who suggests there is is a salesman with a budget to meet. We are very strong believers of horses for courses so tend to suss the boat, the user and the intended use and then suggest 2 or 3 for the boater as a starting point from which we drill down until the boater is happy with what they are about to fit and rely on while having a snore off.

 

As a general comment for general use - stuff that doesn't perform well tend to not last in the market too long, especially in smaller countries like NZ. So most anchors being sold are OK if used correctly. There has been a bit of growth in the asian made knock offs, some of which are poor knock offs. The 3 that do do OK out of china are the rocna, the shovel and the genuine delta (some of it's knock offs are iffy). Ones from china tend to be cheap price based but there is one or 2 who have a horrendously expensive brand sticker on them.

 

Our top pack at the moment -

Sarca - the biggest seller in Australasia and by quite a bit.

Excel - boats are swapping from what are regarded as OK anchors to these a lot which is interesting.

Supreme - a good one and while the same as a rocna the Supreme is better made from stronger materials with far more approvals and NZ made. What more it is cheaper than the rocna.

Racer - the blue alloy Danforth pattern which is my favourite one as a secondary.

Shovel - for the people who fall for the rocna advertising but prefer beter value for money.

 

The rocna is a good anchor, I helped design it so it has to be :P, but it's been captured by brand marketers, to its detriment in many peoples opinion, especially when you sit it next to it's near identical twin the Shovel.

 

Interesting, the current "Boating and Outdoors" catalogue says the Shovel is "NZ Made", has Rocna returned to NZ manufacture?

Yes, we have tried to correct that. The Shovel and Rocna are both made in China, have been for a long while.

Don't believe everything you see on the interweb ;)

Have had a Rocna and now on an Excel. I find the Excel a better anchor for a wider range of situations, but, as SM has said, you do need to use good technique/practise when deploying it. But then, ought we not be doing that all the time anyway?

Yes my 25 llb plough is great and trustworthy, the rocna has a unique edge on the bottom of the shaft if you study it when it rides up in the paw it elevates , then when let loose it slides off with out any assistance to a point where it tips off the boat So when the chain is released the anchor is off it was that I was interested in where’s the plough on my boat you have to give it a shove The comments are all interesting even from the designer

Wowww, some interesting comments coming in I didn't really expect, I do like that though as we regard user feedback as far better info than the mobs who make them. You maybe surprised to hear that every anchor manufacturer reckons they make they best one, I know that sounds hard to believe but it is true :D

 

I see Lewmar is a Excel fan as well looking at their new one. More copy n paste .... again.

 

I have 2 designs sitting at work ready to go into production, have for a while but there's more than enough out there now. Both are a bit unique, one very much so. I'm damn tempted to fire that up as it would be a genuine game changer....but not in the way your probably thinking ;)  Meh, more than enuff on now so maybe one day.

 

I have a genuine CQR and love it.

See what I mean when I've previously said a massive input is the DOTS*, if they have technique they can make most anchors work perfectly fine. I know others who would give you there 1st born before their plow**. Like Chariot they have mastered the beast so can use them to their full potential and be happy as Sperm Whales in a Ocean. Even though they feature in the 'nowhere to totally crappy' end of most tests*** these days many people still love them and have no problem with them.

 

* - DOTS = Dick On The Stick ....the driver, the boss, the anchor setter....which probably means you.

 

** - 99% of the time the only 2 plows we get comments like that about are the C.Q.R and the Manson version made in NZ. Most of the others are crap, just do not go there.

 

*** - We regard most test as a tadge iffy as they have too many variables. Using boats is not really that good as the speed at which the power is applied usual varies, depth can change a little easy pissing with scopes, wave action comes in and things like that. Then the manufacturers have a crack and some of them, gosh horror shock...not really, do tend to push the highs and lose the lows. One name pumps out a 'holding power number' based on a 1.2 second blip during a total of 6 different pulls of about 10 mins each. That blip spiked to nearly 3 times the average load for that anchor. It was probably caused by hitting  rock, a shell or something like that. But that's dodgy in my books and no different than saying we've tested a Wickydo Rickshaw and got 200kph ................ without noting that was as it was falling to earth after being pushed out of a aircraft at 30,000ft.

 

So suss tests but just look for trends i.e the 'Hook 5000XLS 4x4' did OK in this test and the last few. That would indicate to me that anchor is indeed OK.

 

Also watch for regional stuff. In the EU they have anchors we don't see bugger all of and visa-versa. Same with the US, even Japan. Just because a anchor is not in a test it doesn't mean it's bad. There are many reasons most tests don't have the odd name or two in them. The share number other there is a common one.

 

 

The comments are all interesting even from the designer

It's probably Craig who wrote that, Peters son. A gifted fella on a computer and the bloke who tidied up my main lady, the one in our logo...but not the 4 sisters she recently found she had.

I changed from 25 years of plough and Danforth use to a Rocna 10 years ago, it's performance has been nothing short of stellar, totally trustworthy , and it's on the small side of the size threshold for my boat.

It's the last of the kiwi ones as I understand it, I haven't been able to bend it. I know there was a bad batch of sub standard steel when the manufacture went to China first, but I haven't heard any bad things recently once that was addressed.

Like Steve says , the new generation anchors were a breakthrough and became much easier to set, you don't need to finesse them in like the old cqr, I'd still trust a plough as long as I knew it was in properly.

Thanks KM. Rare common sense comments from within the trade. We've used everything from the old fishermans pick, good but needs heavy chain and impossible to stow, thru danforth(great but hard to stow ),plough,delta,grapnel,rocna and from experience a lot depends on how you set it. The Jaffa method of roaring into the bay at 7 knots and letting it go makes it hard for any anchor to set.Rocna suits as a good all round easy to use example and hasn't let go...yet.

I changed years ago from a Manson CQR to a NZ Rocna.

The main reason was a single event with the Manson.

We were anchored in a bay with smooth, firm sand. The Manson was well dug in, been on it overnight. About 10am next morning, we could see a front approaching, and had a 180 deg wind shift, coming in at about 25 knots. The Manson pulled out, then simply slid on its side over the sand for 100 odd meters, while I watched it.

The Rocna would never do that unless snagged. Its dragged 4 x in over 1000 nights at anchor. Three times it was fouled in rubbish, once in weed. Modern anchors are a huge step forward.
