We are using connectors that are rated as stronger than the anchor chain and in the years since this was filmed it has always performed well. It is not a nice solution but so far it is working well. We replaced the shackles when they were two years old and the are due for replacement again this winter. It also annoys me that I cannot inspect the inner pin of the swivel, but it is massively over-rated for this boat so I pin my hopes on that 😃
The shackle attached to the swivel is a proper bow shackle, the shackle on the anchor is a D shackle and is not rated for side loads. It is good that they have a short length of chain between the anchor and swivel since that should minimize side loading on the swivel.
We were in two minds about the swivel. Whilst it stops the chain from twisting it is also more mechanical links aka breaking points aka thing to go wrong. We have also seen enough bent swivels on other boats..... thus the oversize chain.
@@SailingYachtSaltyLass I'm also very unconvinced about the need for a swivel. However, if you have one this is definitely the right way to install it so that there are no side forces on the swivel.
Generally speaking screw type shackles are rated for 50% of the nominal rated load when side loaded. One thing to be aware of is not to get a cheap Chinese knock off shackle whose actual load capacity is dubious at best. Spend the money and get quality. For 'D' type shackles I do not know the industry standard for side loading - I never used them in my professional life.
OK -- it is mousing not ceasing but fine!!! What I did not understand is why add 2 shackles and a short piece of chain -- when the swivel is designed to fit directly on both the anchor and the chain -- all you seem to have done is add weakness to your anchoring system. The Ultra Anchor Flip and Swivel is a great product that ensures the anchor (an Ultra preferably) is correctly oriented before it enters the bow roller. For a ceased shackel -- after long attempts with WD40 etc... and brut force -- Use an angle grinder with a cutting wheel if you can power/use it safely ...... or a good quality hacksaw and a few beers.
Hi Andy, thanks for the comment. I will be honest, we have never been happy with the shackle solution because we agree with you - it just looks like more points of weakness. Each season we have wondered whether to bother, but all the reports we have read say that the biggest weakness is sideways load if the swivel is attached directly to the shank. We do replace the shackles and you may see us doing that in a later video during lockdown (I forget which vid it is in). I will have a look at the Ultra Flip, but we may just go to using two shackles as a "swivel"
Five failure points compared to one if you used a rated bow shackle like a green pin connected directly to the shank

After having it on for a year, we are thinking of taking it off again. We still have not made our mind up on this.

Agree that swivel direct to anchor is a side load issue. I have seen the resulting deformation of the swivel when this is done.

Binary is very cool, might limit the options for crew in the future though 😂
Always a risk... but we can expand their education. Count after me.... 001, 010, 100, 101, 110, 111, 1000,........ :-)
