Tie what in looser?
Get a lighter/thinner batten for the top?
Why I should I have to change what came stock on the boat? <-- this is going off, what you answered me when I asked about the adjustable trapeze lines.
Leave the top batten out entirely?
That wont do anything, just make the top flap around.
Ask the sailmaker (or any sailmaker)?
I would if only I knew one, hence why I posted it here.
