I havew a picture of the Maxi yacht Wild Oats 11 in a mag and you can clearly see that it is a crosscut sail with load path yarns. Have a look at the Genoa where the battens are the are seams.
Ummm NO. what you think are seams at the batten pocket are in fact extra fibres running from the front edge of the batten pocket to the luff of the sail. These were introduced in 2007 accross th 3DL range for GP spec sails. basically it improves the longevity of the sail with minimal weight gain. essentially it acts like a longer batten than is actually there. A bit like a full battened jib without the handling issues of a 38ft long batten <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
