Thank you for your reply. I totally agree with you that the 11.0m CR, 11.0m OD and maybe even the 9.5m Starboard Raceboard Sail are faster than the 8.5m Glide in light winds. However I still think that a 10.0 or 11.0m Glide would be even better for such conditions. It's deeper profile, tighter leech but especially it's better handable lighter weight could result in an awesome light wind machine.
Have fun, TJ
