Rocna 10 vs CQR 45

[MicHughV]

I had a helluva time with those SU carbs. I had to pinch my mother's sewing machine oil to fill those dampers, but it required weekly observance to keep them at the correct level.
It had a few other minor twerks here and there. I don't recall the model year, but I owned it around the 1971-72 era.

Beats talkin' about anchors

[Wallaby]

Look at a Rocna--it looks kind of like a shovel.
Look at a CQR-- it looks like a farm plough (plow)


Which digs a deep hole? Which digs a long shallow trench and pushes rocks aside?


The best anchor for digging deep in soft mud is a Fortress on Deep set with a few yards of steel cable to nylon rode. Chain does not cut through mud unless it is goo. The cable is a 'hot knife through butter' but be prepared for a difficult recovery. I keep an FX-55 with 22 feet of 7/16" cable as a dedicated hurricane anchor.

No, a CQR doesn't look like a farm plow.

See 5 bottom plow in attached photo.

Each plow blade is 1/2 a CQR.

That's a huge difference

CQR's work fine if you know how to use one.

No experience needed with the new gen anchors!

I'm an old-fashioned sailor who still raises my anchor by hand on my 10,000 pound sailboat.


Until I lost it on a hopelessly fouled bottom, I had a 35-pound Delta with 30 feet of chain (the rest is rode) that never dragged. I could break it loose by hand.


I replaced it with a Rocna 10 with 30 feet of chain. No hand raising there. The boat must go forward and break it out no matter what conditions and what kind of bottom. Usually, I have to wrap the chain around a cleat because I can't hold it.


Drop that Rocna anywhere and it sticks like glue. On muddy bottoms, it will come up with 30 pounds of muck. It's good to the point if being bad.


But here's a story about the limitations of all anchors.


A couple of weeks ago, anchored off the Anclote Keys in western Florida, we along with a companion sailboat got hit with a fair weather waterspout in the middle of the night.The roar jarred us awake.



By then, our boat was being pushed back rapidly by the waterspout. With that Rocna, 30 feet of chain and 50 feet of rode in 8 feet of water, we were pushed a quarter mile before the Rocna bit as I ran the diesel into the wind.


The IP with us had a 50- or 60-pound Bruce with 80 feet of chain. They caught the brunt of the waterspout and miraculously ended up in an anchorage a half mile away.



No injuries. No damage. But whew.

No similarity at all. And the fact that CQRs are referred to as plow-style means nothing:

Not really.

No, but the CQR is a classic.

It's nice to have both though.

I had a new gen anchor as backup to my CQR for quite a while then finally hooked up the new gen as my CQR was getting a bit worn

The CQR is now the backup.

No brainer. Use the free 45# Genuine CQR for a while and find out for yourself whether it works for you.


For the record, had a 45# CQR as a primary and a Bruce 15kg as a secondary on our previous CD36 for over a decade, and half way around the world... no complaints.


Now we have an ancient 35#CQR primary and a 10kg Rocna as a secondary on a Shannon 28. The Rocna is usually used only when we need two hooks out to limit swinging room. Still no complaints.


Folks who malign the venerable CQR might need to up their anchoring skills, me thinks. Most, I suspect, have never actually used one, and are just parroting what they perceive is consensus.

I had a 45# CQR come unset one night at 1am when anchored on a steep soft sand slope. The wind had shifted to a westerly off shore 25 knot Corumel blast in the Sea of Cortez, a common occurance. I was heading out to sea. I have checked my CQR set with a snorkel in shallow soft sand bays and noticed it can plow a long furrow before setting. I bought a 50# Danforth anchor and now use it exclusively in the Sea of Cortez in soft sand with good results. The CQR worked well in the rocky PNW and SE AK. I have 300' of chain.

Now I'm sure, anchor belief is harder than religious belief!
Please use any anchor you belive to be the best, but don't criticize those who use other anchors; most of them probabily with much more miles behind than you!

The type of plough used by farmers comes in many blade shapes, but some of the traditional hand plows are close to the shape chosen by many convex plough anchor designs.

Unfortunately, these designs also have a tendency to neatly plough the seabed in some circumstances.

Ah a classic, garage kept and brought out for show occasionally!

[Wallaby]

For those who think anecdotal evidence of anchor superiority is the standard to judge by, consider that the CQR was designed in 1933, and the CQR stands for Coastal Quick Release. The name alone should make you think twice. That said, the CQR dominated the anchor market until the 1990s; however, the competition was not much better than a concrete block. Taylor's patent from 1934 is worth reading--you can find it online. He notes the derivation from the plough-share!

In the 1990s, new anchors were engineered, and much like computers replacing slide rules, quickly dominated the market. There is likely a reason, anecdotes aside.

The old and worn CQR that came with my boat worked fine for a bit over 10 years. And would probably still be fine but I got the 25 lb. Mantus M1 for $300.

My old 20 lb CQR was a bit undersized also for my boat.

As far as plowing,

I mainly used an Oliver 7 bottom plow when I was working on the farm.

it did a fine job.

I was 16-17 then and once broke a sheer pin and that whole section came up. I actually didn't know there was a sheer pin on each section up top until I hit that stump

That was the only time I hit something hard enough plowing about 800 acres

Ours had hydraulics also for raising and lowering.

The old Oliver 1600 diesel Tractor I was driving would put out a bit of black smoke when those 7 bottoms first dug in then it would level out and pull
