I have no experience of hanging off drogues or parachutes but John Hitch, who designed the ubiquitous Hitchiker cats, recommended not using a bridle as the tensioned part of the bridle has the tendency to trip what would be the leeward bow.
 
Having said that I would have thought an adjustable bridle set with the windward arm slightly shorter would tend to keep the boat pointing just off the wind to leeward so that any 'tripping' effect would be on the leeward hull.
 
When working out where to put the anchor roller on the Visionarry there was a lot of debate over which way the boat would tend due to windage. I ended up putting it about 300mm to leeward of the midpoint between the hulls, more from convenience than any great incite. When anchored off a beach recently in 20 knots she laid dead to wind.

Subject: [harryproa] Drogues and Para Anchors

Anyone have any ideas or experiences (second hand welcome) of drogues
or para anchors on pros?

The thing I like about the proa platform is that sometimes folks
carry both drogues and anchors, deploying one off the the stern and
the other off the bow.  Starting with the drogue and moving to the
para if conditions worsen.  This can lead to complications with
reversing the boat to get the para out even as conditions are ramping
up.  The obvious point being a proa is lonigtudinally symetrical, and
therefore one can throw the drag device off of either end.  The boats
and rig are also symetrically placed.

There may be bad news also such as the uneven windage on the hulls
once streaming the drag device.

Any thoughts about how this could work, broadly from attachment
points to lights to storage and deployment, all idea welcome?
