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?

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.
