i think you can have a big foresail, by having a nother jib track back further on the main boom, plenty of overlap.
good idea about different weight cloth going up a sail.
diff. battens or tensions sounds right, i see the battens really bending round when i reef down in fresh winds, which is when the sail shoud actually be flatter - so stiffer battens then mmight help it stay flatter and not so full in shape.
btw would the bigger overlapping jib make the luff /head stay go even more saggy?
how lee efficient is the easy rig's sagginess causing?
is this a reason for some preferences to uni or schooni?

Did the Rob change the Visionarry rig after the website stopped being
updated, because it is listed at 774 sq ft on
www.harryproa. com/visionarry. htm, which I figured is close enough to
your numbers.

Btw, I am not against just using a taller mast. Regardless of how big
I make the sail plan, I am going to have to have a mast that comes
apart into 2 sections to fit in a container. a 39' mast, with the boom
9' up will never give me enough sail area.

What are the boom dimensions you are using to get that sq ft of sail?

I am just exploring alternatives. Maybe it is time for Rob to hop in
and just remind me that I am an idiot and I can switch to some other
silly idea <grin>
