The best drogue is a catamaran mast and sails - THE CREW COULD HAVE INVERTED THE BOAT
I think it would be better if one person could right the boat. A simple righting bag, The crew rescues the boat then goes for MOB. The inflatable sausage is a great idea.
I sail with a 7lb fortress (light) and a large righting bag. Upon capsizing I throw the anchor and rig the bag. Even if the anchor doesn't bite it seems to add enough drag to help the bows point into the wind.
