Rocna roll bar

[NahanniV]

Rollbar can be handy if you don't have a Christmas Tree Aboard.

If you want to know wha the roll bar does, just look at some of the many videos of people dragging a roll bar anchor laid on its side on a beach, the roll bar positions the anchor so that the tip can “bite”.

However in real soft mud the anchor can still lay over on its back and never set, the roll bar just sinks into the soupy mud, so nothing is perfect, nothing is fool proof, there will always be a better fool

Possibly a float with enough buoyancy on the top of the roll bar would right an anchor, always?

Just a note that when anchoring in mud with my Rocna I don't lower my anchor until the boat is moving astern, including in current. The anchor "swims" downstream and always orients itself properly until it contacts the bottom.

It also helps, having all chain rode, to not have a swivel; the anchor in slack water will lower itself with the point facing aft. Not something I count on though except in water clear enough to see how it lands on the bottom

I have two favorite sayings about foolproof devices.


1. It's impossible to make something completely foolproof because the damn fools are so ingenious.


2. If you make something completely foolproof only a fool will be able to use it.

(after ***** around with your anchordesign just make 150% sure to never ever anchor upwind of us!)

I don't need any psychobabble on how I should think about my anchor.

That could well be very true.


However, that wasn't Jim's point.

Ecos,

Why don't you take a look at this thread: "Videos of Anchors Setting," started by Panope.

Our own anchor is a Manson Supreme. We anchor out about 95% of our time, and have for many years, now, having cruised for a little over 30 yrs. continuously.

I thought the liability question raised was interesting. But, the roll bar IS needed, to help the anchor turn over.

Your hacksaw, your decision.

Gotta love anchor threads. Just upgraded from a Delta 33# to a Rocna 44# which will be all the anchor my little 35' ever sees.

Oh missed this one first time out
What a load of rabble
Anchor threads da Best

Point 1. you do not remove items from a well deigined and tested product , which has been proven to be a decent design from around the world , it would be like taken the wheels of your car because you can

Point 2. An Item designed to work and made that way , works because it has been made that way

Point 3 . By removing or altering a desigin on a product , WILL effect its usage
to the point that it is MORE than likely it will not work as intended.

Point 4. I have a Rocna and I have never had any of the issues disscussed it has held in WEED, MUD,SAND, in storm force winds across my Country.
when it comes up with a bit of anything I lean over and A. remove it , or B.
wash it off

Point 4. there are other anchor designs out there , it would be like removing a fluke of a Delta because you can

POINT 5. This thread is silly who in their right mind would remove a large , part of an Anchor which is there to stop you drifiting in which your life may be in Danger

Point 6. Feel free to flame me I can handle it

Not about to flame you, but why quote the quote you did? Not sure I understand that??

Fat fingers and a mad mind

[Kintala]

We have a Mantus and the company told us we could remove the roll bar with no ill effects. The one on the Mantus bolts on. We've never felt the need to do so but we can if we wish. I have to say it does provide a really convenient way to tie it down to the pulpit when we're on passages.

I've had it happen with Mantus. I've had Rocna anchors roll over backwards and stay stable on their backs in very soft mud (rare, but happens).


Once I neglected to powerset (lunch stop). I noticed it while swimming. On it's back (roll bar removed--long story).



Anchor enough times and it WILL get on it's back. Believe it or don't.

you cannot anchor while moving forward?
That suggests a borderline unseaworthy anchor. What happens when the anchor is pulled out when current or wind changes? What happens if you are still moving forward slightly under sail or fair current?
I would suggest finding another style anchor.

The Rocna is a much better anchor than the Delta. Trying to make a Rocna more like a Delta is going backwards in my view.

Agreed, both these anchors weigh 10kgs. Worth noting the extra thickness in the Delta shank compared to the Rocna. Instead the Rocna clearly has extra blade area. The owner of course has a choice, do you want extra steel in the shank or a larger blade area?

Why would anyone buy a rocna with a roll bar and then opt to cut it off? It doesn’t sound like a good idea... but If you decide to do this maybe you should post your location whenever your on the hook so others can avoid you..
