I have other versions of this sail available for less of course.

Gee, I don't need all that expensive full batten stuff and 2 reefs.

Tri-radial Pentex, regular length tapered battens with the top one
being full, 5/16" boltrope, 1 reef. ****, if a full batten Kevlar
number is $1600 your guy should be able to do this for $900. Of course
I would want to know the name of the loft and the brand of cloth.
