Jay,

Here is what a catamaran (wharram tiki 26) owner did:

"I had a Tiki 26 with a Jordan Series Drogue (I still have the drogue
but not the boat regrettably). The attachments for the bridles were
Stainless 316 chainplates approx. 25-30 cm long, 3-4mm which were bolted
through the inner guwhale approximately halfway between the aft beam and
the rudder. They had full length backing plates too. I agree with Paul,
I would not attach to the aft beam.

There was an aft trampoline so the bridles were attached under that with
the drougue itself sitting on the tramp ready to deploy. The whole lot
was clear of all other bits of kit like traveller/mainsheet. "

I would think that both hulls meeting the waves together would be the
way to go, but some experimentation would seem to be in order. I've
read of some who would attach lines led to winches from the bridles in
order to use the drogue to steer. That violates the K.I.S.S. rule, though!
