I believe wire is the benchmark. All manmade line materials stretch slightly more than wire. Do your research.

Is this still necessary? Also, will the draft move at all in a high tech sail? (I'm not arguing, just trying to get my head around it.) sam :-) From: Jerome Tauber Sent: Tuesday, December 3, 2013 7:16 PM To: cnc-list@cnc-list.com Reply To: cnc-list@cnc-list.com Subject: Re: Stus-List Old Sails Suck Un der load or in a puff the halyard will stretch and loosen the luff causing the draught to move aft. The greater the load (more wind) the more stretch, exactly the opposite of what you want as a racer. On the other hand, for a cruiser, stretch in a puff will take some of the pressure off the sail causing less wear and longer life for the sail and allow some spillage of air if the sheets stretch as well.

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?
