If you have not got to the bottom of this by the time I come out September 8 and if our paths cross, we could do some tests, like try my gypsy on your windlass, we could compare chains what ever. You could visually inspect my windlass in action….Looking at your video earlier something ain’t right. Nick S/Y Amelia AML 54-019 Leros GR

Chain, yes, it is easy to measure, but who can say what the tolerance is...and it will certainly need replacing because of age or corrosion before stretch or wear.
Gypsy, I don't think so, and every case where I have been asked what's wrong with the gypsy, it was either the wrong chain (DIN vs ISO) or the chain obviously needed replacement.

Hi Dean,
Looking at your picture in the pdf, it looks like the chain links are too small (as if they were DIN instead of ISO). Maybe you can measure the distance over a few links and check notes with others? I don't understand why it should jump more on releasing than retrieving, though. However that it twists more when it jumps while releasing might be explained by the better guidance provided by the grooved roller, compared to the hause pipe. As the chain is about to slip, the links are positioned correctly (with respect to a twist) when retrieving. Before wintering, I fully rinsed the chain and it went in and out without any problems.

Ruedi,
Thank you for the video. I am envious of your windlass performance :) All, I have today confirmed that both chains are ISO, 30 +/-0.5mm links, 315 +/-2mm + per 10 links. On close inspection, I am convinced that the gypsies are correctly labelled. They are stamped with 203 (ISO) and the pockets measure up and match the ISO chain. When I had things stripped down, I tried reversing the primary gypsy, per David's idea. When I anchored this afternoon the performance was better. There were a few skips for the first 6-8m then it settled down and ran smoothly. Maybe I have a worn out gypsy (after 12 months of use). I have also, supplied all the information about the problem to Lewmar Tech Support and asked what they recommend. In particular, would the addition of their optional Control Arm Kit solve the problem. -- Dean Gillies SV Stella *****, Amel 54-154 |

Nick,
Thanks for the offer. Regardless whether I have a solution, it would be good to catch up for a beer. -- Dean Gillies SV Stella *****, Amel 54-154 |

An interesting comment from UltraMarine owner. Food for thought....

Hi all,
Two more videos taken after turning the gypsy upside down. Observations: 1. The deployment is much cleaner than before. 2. In this 45 second deployment, there is only one skip/rotation which happens after 30 seconds. 3. It is clear that, on deployment, every link impacts the ridges between the pockets on the lower half of the gypsy. This would seem to create a significant amount of wear on the lower half of the gypsy. This could explain why turning the gypsy upside down improves things. The lower part of the gypsy may be worn out. 4. In the retrieval video you can see that there is a small twist in the recovered chain between the gypsy and the bow roller. This was the twist caused by the deployment sequence in the video immediately prior to the retrieval. 5. The retrieval process does not create the same impacts to the links as the deployment. It seems to me that there needs to be a mechanism to guide the chain more effectively and cleanly on to the gypsy during deployment. -- Dean Gillies SV Stella *****, Amel 54-154 |

Hi Dean, when I watch your and Ruedi videos, what immediately catches an eye is that Ruedi's chain links lay very evenly in the gypsy. take a look at screenshot below. and in your videos, chain is sticking to one (pulling) side of teeth. seems like holes are larger and that eventually kicks one link out.

Hi Ruslan,
Yes I noticed that too, also that the teeth on Ruedi's gypsy look taller than mine. However, we have to be careful because Ruedi has a DIN chain and matching gypsy. Maybe that is the reason. -- Dean Gillies SV Stella *****, Amel 54-154 |
