Sure,

And two sticks carring two sails is more drag, vs one.

More sail area won't due you any good if its in the wrong place.
Or needing to use deep boards to compensate for extra sail area in
wrong place to stay in control adding even more drag. Its a proa no.

Going off shore most carry spare of everything that they can.

Steer By sails alone on a proa that needs deep daggerboards (prove
it) explain that.

Weather cocking on a proa balanced right easily does that with a
single sail.

Each to his own i'd agree.

But Doug said he thought his boards needed to be further out
towards bows for better control.

So I simply gave a alternative, a glimps of what I thought worked
well. Why would some take offense to that. I share my ideas knowing
nothings set in stone I know this. Its nice to get different
perspectives on different problems and solutions.
