John,

on a totally wild tangent: You mention fully battened jibs as a performance enhancement. Why are fully battened jibs better than partially battened jibs? Full battens make the sail more stable shape wise, but how do you alter shape on the jib to changing conditions with a fully battened jib? Besides, I know firsthand how much work finding the right battens can be. I am not certain if fully battened jibs are faster over the complete windrange now that we have selftackers on most performance boats.
Sorry for the rhetoric and for jumping on your argument with both feet in what is a totally different discussion.. <img src="http://www.catsailor.com/forums/images/graemlins/crazy.gif" alt="" /> It's just me having a pet theory that fully battened jibs vs partially battened jibs have not been thoroughly tested.
