It depends on the ratio of height to circumference about the mid section. The higher this ratio, the great the coefficient of drag, and thus the harder it is to get around the bouys. The only way I see you getting around this handicap is to shave your beard and your hair to reduce the wind resistance, along with wearing a speed suit perhaps. Maybe you could put 6" spacers between your bindings and ski. That would get you some extra reach. But then I'm worried that could affect your stack and the outward cast of the ski, especially with your wing upside down.
This is what happens when replying to a buddies ski question while laid up with a season ending shoulder injury.
