Have any of you re-fitted with a split backstay tensioner? Can you share details about how you
installed/reinforced the attachments through the deck?

I did that with one of my old sailboats. I added two chainplates, one
on each side of the transom to anchor each side of the split stay. The
only attachment to the deck was a pad eye for the lower end of the 4:1
adjustor tackle. Both the chainplates and pad eye were reinforced
with backing plates. The upper end of the adjustor tackle went to an
arrangement of two blocks that rode down on the split stays to
increase tension as the tackle was lowered.

This might provide some food for though: http://www.harken.com/rigtips/back.php.
Sorry not to be more specific on chain plates and such, but it's hard
to guess what will work for you without know what boat you have...

I did this on my current boat without drilling any holes.

For the tensioner I used an off the shelf backstay tensioner (http://

Then I got some longer pins for the existing chainplates and attached
some dinghy shroud adjuster fittings (a couple of flat tangs would do
as well) to the existing chain plates using the longer pins. The
other end of the fittings anchor the backstay adjuster blocks etc.

This arrangement has worked flawlessly for close to ten years now.

I'm liking that idea

Then I'm guessing you already have a split-backstay?

Right. The boat came with the split backstay. I added the tensioner.

This is the setup that I'm looking at. I'm guessing your chainplates were added to the exterior of
the transom. What did you use for backing plates?

Yes. They were relatively small and did not create an appearance
issue.

Aluminum plate, about 1/8th with SS fender washers over.
