i can only comment on my experience with a nacra 5.2 where hull alignment is very easy and the top tuning advice is to actually slightly misalign hulls slightly toed out...
Ah no. Good way to make it a pig in light air.
True for a bridle foil boat like a 5.8NA, maybe not true if you have bridle wires.
Why would you say that? Would it not act like a funnel for the water to pass between the hulls upwind and downwind? I don't even want to think of the stresses of the hulls fighting each other. Would it not try and make the hulls roll towards each other from the top of the deck? I'm not seeing the benefit.
