Chain plate

The word chain plate is probably used because a short piece of chain was attached to it and stays are connected to this chain.

Does anybody know why chain is used?

before the age of wire rope, they used chain between the dead eyes and chain plates. Chain was the only 'most reliable' thing on a boat that was made to hold the rig in place.

So Rich, now someone is going to ask, "What's a dead eye?" That would lead to another wood discussion about the best species for this forgotten piece of very effective sailboat hardware. (I'm suggesting Locust, not a wood often mentioned often in boat construction:-) Personally I think we should all go back to dead eyes

Re: Chain plate

Wooden Ship-Building By Charles Desmond is a good source for illustrations of dead-eyes and chainplates.

When wire rigging is entirely replaced by dyneema, amsteel, etc in the future, dead-eyes made from 'a polymer' will most probably reappear ... theyre so damn easy to use. :-)

They are already here. But in anodized aluminium rather than polymers. The weight savings of the polymer is marginal if any, and the aluminium lasts much longer in UV.

Frankly I think we are at the end of wire rigging. Sure it will go on for a number of years, but at this point I wouldn't rig anything with it. For most boats dyneema, for the rest carbon fiber rod. And wire no longer has a place on boats anywhere buy electrical wire.

Re: Chain plate

Maybe this is a thread hijack . . . . . . .

How does Dyneema compare to SS wire size for size, strength for strength, cost for cost?

In other words, what Dyneema would replace 10mm 1x19 SS wire?

And can dummies splice/swage/attach Dyneema easily? Is there a "Sta-Loc" for Dyneema?

I'm contemplating a full standing rigging replacement and I believe there is a significant weight saving using Dyneema. But I've been using SS wire or rod for 45 years and to change to "rope" is something of a wrench.

Re: Chain plate

It would be very nice to use Dyneema/Amsteel for standing rigging. I considered it when replacing it a couple of years ago but that nagging vulnerability that rope can be cut by a sharp knife, dissuaded me from using Dyneema. The strength and stretch factors are the same as wire but the "cut" factor is not. I did use Dyneema to replace the lifelines and for running backstays for my storm rig. Splicing in eyes with heavy duty thimbles make the ends of Dyneema very easy to do. I used regular s.s. turnbuckles for the runners but would really like to try using deadeyes.

Re: Chain plate

hear me out here...

what if you have a metal covering OVER the dyneema....like a sheathe that would protect from chafe...cuts, etc...it can be lose fitting, doesnt have to be real thick...

doesnt have to be metal, just something that could proptect against cuts, and sharp objects...

best of both worlds?
