We have just finished testing our Dyneema Chainplate loops to over 4, 000kg. They didn’t break, although something did at about 4,175kg.
Hopefully we have caught it all on video which will be out soon 😊

Dave, Looking at thisblog item, do I now understand that you have moved away from a “through hull” chainplate principle and onto a “through deck” system? If this is the case, can you share some comments about how and why you came to this decision please?

Yes, that is correct. I tried to explain our final design and thinking in https://sustainablesailing.net/2021/04/17/final-dyneema-chainplate-design/
Basically, I felt the through hull option was getting too complicated. Our small backing plates have worked (mostly) for 44 years so the through deck option with huge backing plates (and knees to the hull for the cap shrouds) should be a lot stronger than what we had as well as much simpler.

Simon, I’ve had another, simpler idea for external chainplates. I’m just trying to get it written up.
