Take a piece of carbon laminate tubing, length 3 mtr.
Say the proces of carbon cloth laminating is accurate in reproducing the wallthickness to say 2% and lets assume for simplicity that this variantion is constant along the full length of the tube and that there are no other factors (in reality there are).
bad form to change a post that has alreay been commented on.... You had alloy as your example before realising it wasn't really working for you hey....
You may be a very good sailor, but you may want to stick to what you known best; driving a boat fast. Because in all honesty you are not very knowlegdeable about any engineering stuff and that includes the 3D sail stuff.

Funny that I get employed to fix problems engineers create then... Still waiting for the proof on the 3DL broadseam too by the way. I have a contact list for North Sails here if you want some email addresses or phone numbers.
Theory is just that... theory. The real world is different to what you have learnt in school. There are some companies and individuals in the sailing world that can and do what you claim is impossible. Well the proof is in the doing and they have done it. BMWO have two masts for USA 87 that are identical in any and all practical ways. The masts are over 32 metres long and have many "variables" like spreaders and associated standing and running rigging. By your reasoning the bend should vary between masts by metres at that length! when in fact the variances are measured in 10ths of a mm.
Stick to school champion, I'll stay out here in the real world. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
