Our mizzen forwards (or maybe it was shrouds) were bent and they appeared to
have been done do before being installed. We just put them back in as-is
after inspection by a rigger and polishing by us.

Actually I am more concerned about twisted chain plates. Of those that have
removed/replaced your chain plates, have you had any that were twisted? My
two forward most plates are both twisted and a friend of mine is telling me
it must have been done prior to installation (meant to be like that), and
the force required to twist that steel would not have been transmitted
through the rigging. Also, one of my back stay plates is slightly bent. Just
wondering what others have found.
Thanks

One some of the earlier boats they twisted the forward chainplates so they would line up with the rig. Mine came out the same way and I thought they had been damaged underway. It wasn’t until I installed new straight ones that I realized they had been bent that way. When you install new plates, you will see that they don’t line up square with the slots in the hull. You can either redo the slots or build up the knee that they are attached to so they are square or have the new ones twisted to match. I chose to build up the knee with fiberglass to line them up properly.

On the later hulls, they didn’t bother twisting the chainplates, so they are not exactly lined up. You would never notice it unless you are looking for it.

I put toggles just below the turnbuckles to account for any misalignment in the chainplates.

My backstay chainplate was twisted. I have no idea how this happened. I replaced the whole thing because it was not strong enough.

I have a sloop design and there is a huge load on the middle of the transom. I had cracks and a buckle to my stern and decided to go for two chainplates mounted port and starboard at the corners- a way more structurally sound position.  I will go by the boat today and post a photo of the design.

Good idea, Bill. An added advantage is the ability to have two main
backstays, one to each chain plate.

I replaced my standing rigging a few years ago. I regret I didn’t eliminate
the delta plate on the Ketch back stay and go with two independent back
stays to the main mast. Would have been about the same cost – a little more
cable, but fewer fittings. I didn’t think of it until a few years later
when berthed next to a similar-size ketch with two back stays.

I still have my rigging to replace. Any disadvantages to twin back stays. I assume you would have more weight and windage aloft, but I don’t know if that would be significant on our boats.

Paul

Paul,
The lower sections of my back stay are 11/32″. I think the upper is 3/8″
So weight difference would amount to the difference between one section of
3/8″ cable and two sections of 11/32″ and a few less fittings. I doubt
that would be significant given the low aspect of the ketch rig.
That said, there must be reason Pearson used the delta plate. Given the
additional fittings, which also add labor cost, it probably would have been
cheaper to go with two back stays.

Here are a few photos illustrating the pieces I fabricated for the
double-backstay masthead connection. Not sure it was an ideal solution,
but it’s holding.
