Blue, although PHRF does not penalize for multiple kites, they do take into consideration the format... you should check with FRICTIONLOSS about use of the ASO...he carries the penalty and uses it alot, especially distance races. Bear in mind that in the CARIB we are using the CSA rating, which takes the SIZE of the sail into account with the rating. Let me know what you are thinking...and talk to the measurers in Antigua. the redhead
