Why code red sails aren't balanced simetrically?

[Danilo]

Hi, I'm currently using a Severne Code Red 11,0 and I can't understand why I cannot balance simetrically both sides of the sail. Actually, when I sail ''looking'' to my right hand, the harness line on this side is 5cm back comparing to the other side. I talked to other people and they told it also hapens wirh the SSR. Why it hapens with those sails??? Thanks for your attention, Danilo.
