I don't know how feasible this is, but I'd definatly do the upgrade if there was a class. Some thoughts- <br> <br>1) Turbo seems to imply a uni sailing with a jib. Maybe Hobie 16MX is a better term. <br> <br>2) Would US sailing give it a PN if there was no restriction on sail area? <br> <br>3) How bout getting rid of the comp tip requirement?<br><br>
