Hi again Ricky,
OK, I got the '07 Severne archived website to download.
I could not determine if they were specifying the 70% Carbon Blue Line 430-21 RDM,
or the 75% Carbon Blue Line 430-21 SDM (Std. dia . mast) for the 6.5 '07 Gator.
Perhaps someone form the Severne Team can clarify which mast the sail was designed for, but I'm reasonably sure either one will work pretty well.
I've rigged and sailed a few 7.5 m2 Gators in the past 3 years, and they are nice. Good power, light feel, well made.
Hope this helps,
