Lucia 40: Lucia 40 / Anchor chain pyramiding

Yes for sure SS chain is the best for making a flat pile, but 2500$ for 200ft is much more than a 300$ pyramiding preventer.

I’d be keen on a solution for the Lucia chain piling.

If I manually move 35m to the Starboard side of the locker the remaining 30m will leave and enter the locker generally without piling and interfering with the windlass. If however input out 40m of chain it will always pile up and interfere with the windlass.
SS chain I understand while slippery for the anchor locker is also slippery on the sand / bottom and I’ve heard isn’t as good as galvanised chain.

... and the aggraving factor is that the chain fall at 2 inches of the portside bulkhead, removing 1/2 of the space plus the proximity of the aft one to pile the pyramid.

I will sketch something like the cone, fixed on the bulkhead to push the chain more on starboard. Do you think just 3 inch more and adjusted a bit aft, maybe 1/4 to 1/2 inch, so it will have tendency to pile more center and forward would help ... to pile the full 60m without jamming.

When FP made their trials, the chain was brand new and they did not realized that with a 2 years old one... there is a problem.

Do I remember I saw windlass where the chain enter on the portside, turning counter-clockwise, I think so ! ... so the chain would fall 3 inch more on starboard ? Too many things to think when designing a cat... sometimes they forget one... or two.

I think my chain is smoother now after 18mths than when new, and piles less. The galvanising has had the rough edges knocked off.

Looking forward to a pic.
One a seperate note, my factory supplied bridle failed in .53kts. :-(

Thank you hobsonlea...
Good observation... I thought it was the opposite for the chain friction because of all the barnacles, weeds, sargassum, rust, etc that stick to the surface would increase the friction in the pile ... like the one in the video.

Will they replace it?
I tried splicing for the first time and made a bridle based on Cotemar's photos and info; it's as strong as could be (maybe not a pretty splices!) and held without the boat sailing back and forth at all. We're in the midst of selling the tri. The bridle stays!

Regards!

I don’t think the bridle failing after seeing 53kts at anchor is a warranty issue. The bridle supplied is simple and works, but needs beefing up for stronger winds. I could have requested a non std bridle, such as the Mantus bridle, or made my own. I’ve now made a new bridle and also a backup bridle.
