While what Ron said has some effect, I find that entry angle is more affected by forestay tension, so given that you have your hi-tech genoa halyard tension set to get the draft where you want it, try cranking the backstay tension up a bit and notice how the entry angle changes as the forestay tension also increases

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.

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.

Tensioning the halyards on the old sails stretched the Dacron on the bias and moved the draft forward. It can't do that on the kryptonite one! A bit more explaining please! sam :-) From: niall buckley Sent: Tuesday, December 3, 2013 4:31 PM To: cnc-list@cnc-list.com Reply To: cnc-list@cnc-list.com Subject: Re: Stus-List Old Sails Suck The main difference is that the new sails dont stretch and their shape is factory engineered. You will still adjust mail and genoa halyard tension according to conditions. You will likely not ever require a Cunningham ever again. Have Fun.

Although I have done a couple of Swiftsures. But I like passing boats and hate it when boats pass me! My boat has been pretty well upgraded with all rope halyards; new adjustable genoa cars; self tailers; new traveller; barbour haulers; and new Dacron sails 5 seasons ago. I sail with a 135% genoa on a furler. While sailing I adjust the genoa halyard regularly to move draft in the sail as the wind changes. (I do the same with the main too!) Now the question: Late this season I bought a new high tech, Kevlar, carbon, kryptonite, 135% genoa. I'm assuming I don't adjust halyard tension with this new sail as I don't think the sail will distort like a Dacron sail. Similarly, when I buy a matching main, main halyard and Cunningham adjustment will become redundant. Am I correct with this assumption? If this is correct, are there any trimming adjustments with these new high tech sails that I should become familiar with? Do you trim these newer sails any different than the old Dacron sails? What new techniques do I need to absorb?
