Last weekend, I picked up a couple of Neil Pryde sails at
the Windsurfing Warehouse (South San Francisco) swap meet.
The 5.5 is a 4WD, and the 5.0 is a Dynamic Cam. Both
are convertible RAF/cam sails.
I read that Neil Pryde has an instruction book which comes
with their sails. My question is whether the instruction
book is worthwhile pursuing, or if rigging by downhauling
for twist-off and a loose leach covers the essentials.
Your comments are appreciated, especially if they roll in
before 3:15 tomorrow afternoon, when I'll have my first
opportunity to try the (for me) new sails...
