Hi Guys.

Sorry to re open this thread again but it seems i cant figure out this issue:confused::confused:. Tried the anchor and bow roller set up before installing roller to boat. However i tensioned and tensioned to no avail as Bruce anchor still wobbled like crazy with the minimum touch. Imagine at sea:confused:.
Attached please find a pic that shows how anchor is setting in roller. Could it possible be that in order to secure ,anchor top of anchor has to make contact with arch in order to secure. As you can see in pic it clearly shows there is a gap between anchor and gap. If im right, what do you think is the best way to arrange matter? Try to find a taller anchor ( in which im changing to stainless )AL1A.jpgANC2.jpg or i beef up the arch so that when anchor tensions with roller it also tensions with the arch?

Thanks
 
The plastic roller can have a groove in them to help steady them. But I prefer to keep my anchor loose, I do not like the winch to have a permanent load on it. I often loosen the anchor after I’ve retrieved it. But the anchor has to have to have a securing lanyard to stop it falling into the sea

i self launch anchor. I tension chain to cleat and secure it with a pin but honestly it wobbles a lot. Roller has a grove as you confirmed but seems it is not doing the job as honestly anchor is like a swing bouncing from port to starboard. Im doing something wrong but could not figure it out except trying to make anchor contact arch as i tried it by hand it seemed steady.
 
The first thing I would do is look at the plastic roller, do you think you would benefit from a bigger roller with a deeper groove?
Or a more narrow groove?
It’s a bit hard to speculate but the shank looks a little high off the deck. Almost like the anchor has too much weight forward, but it’s difficult to get a sense of it from your photo
 
Perhaps an anchor stopper between your winch and anchor chain would help steady it

Does that setup facilitate self launching, if so...To me it appears as if the anchor shank is too high off the deck. i.e. the chain under tension is lifting it. A chain lock as proposed close to the end of the shank may resolve this. See if you can temporarily strap the chain down closer to the deck and see if it makes any difference.

Of course it facilitate self launching in my opinion. Set up at the mo is in a box under the console. Have to open console, removing fishing gear etc, close console, pull the anchor out of box and set it in roller and launch. Vice versa when retreiving. Yes you are right shank is high of deck and when i hold it by hand and end of shank touches deck front of anchor lifts up and make contact with the arch thus making anchor secure. However as soon as i release 1 millimeter front of anchor loose contact with the arch and will loose itself drastically. I liked the idea of enlarging the roller so as to gain the height in order to make contact with the arch. The only help i m getting is from here cause manufacturer said just tighten strongly and thats what i did .

Neither - that's not what the arch is meant for.
Based on your pic, I'd rather blame the bow roller: it only has one plastic wheel, doesn't it?
That's how most of the smallish/cheapish bow rollers are built, but it's a poor solution in terms of anchor holding.
It can work with some anchors, but just by coincidence, not by design.
And even less so with Bruce anchors like yours, where the plastic wheel doesn't end in one particular corner of the anchor shank, hence constraining its movement.
I mean, you can move vertically the anchor even with some chain tension, I suppose?
That's what should not happen, regardless of the arch.
A hinged bow roller with two wheels is much better, in this respect - see below.

Roller is Anchorlift 90101 / 90102 model. It was said that it is a premium bow roller and has 2 wheels. i think something wrong im doing or not understanding concept. Or else roller is not fit for the job although i was assured that they work best with the Bruce:confused:

Is the anchor shaft being firmly cradled by both rollers?

The answer is in these 2 posts.
Imagine the roller you have being a point contact (or with 2 rollers then 2 points in a line) You can tighten against these as much as you like but if you dont provide a third point that is not in that same line the anchor will wobble.
So, deeper groves to cradle the anchor will stop it wobbling.
 
yes i ordered the anchorlift one not the norestar one. it is said that is specially designed for bruce. Thats my concern:confused:

So the third point should be the pin? Or the Chain stopper? Do you know from where i can order rollers with deep grove altough the ones i have have a groove but not that deep.
 
Karnic, do you have a winch? If not, that could be your problem, because the anchor needs to be held from both ends.
Try an anchor stopper, it’s a cheap experiment
