Yep! its awesome, and thats why its so daft to restrict such a good development in the class (if the philosophy is still to have it as a development class...) Right now you can spend a LOT of money on an F16 with carbon beams, mast, pole plus hull construction etc just to get an incremental but definite gain in performance. Yet something as simple as curved boards is not allowed which gives a measurable gain for not much cost increase over straight boards!
