Sam,
While the draft change is minimal, the entry of the luff changes with halyard
tension in the newer materials. You can check this by experiment. Set the jib
halyard hand tight and note the angle of the luff entry; then tighten the
halyard a lot and note how the entry of the jib moved.
This entry change makes it overall flatter or less flat.
As you state, draft is mostly built in.

Sam,
If you are really interested in this,(and you should be, if you want to get the
most pleasure from sailing your vessel),
find a copy of "sail power".
Halyard tension, backstay,lead position,boom downhaul etc are the gears that
accelerate your boat.
I'm writing on Wellness and Anti Aging now, so find the Book.

New main and #1 on Koobalibra C&C115 this past summer. The difference
between these and the 6 year old sails is like high tech winter tires to bald
tires in a snow storm ....

Do you trim these newer sails any different than the old Dacron sails?
