Not sure about "the percentage" of the factory working jib, but H. Wadler has the dimensions
posted on his webpage. He got all these stats directly from the factory.
Note that the X and M have identical foresails, both Jib and Genoa.
The 26x and 26m essentially use the same headsails. There is a 100% working jib and a 150% genoa. Both headsails sold by KHM are built to these specs. Obviously, so are the factory sails by Doyle.
i have a spinnaker from KH,the guys over here are talking about it,i am enjoying it very much.I should have the C2000 jib arriving shortly,then i may just go for a genoa and a mainsail
My new jib arrives tomorrow,it landed in the Uk on friday,it did not take long,thanks for the offer.I have a buddy who has his own aircraft,he has promised to take a shot from the Air of me flying the spinnaker
