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

I'm liking that idea

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.

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

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