Abstract: Though the sport of snowboarding is not new, it has taken many years to understand the specific characteristics which are required for making snowboards. There is better understanding of the dynamic bending properties needed for current riders, especially for the competition driven rider whose demands require boards with different tip, tail and middle characteristics. Early snowboard designers understood the use of snowboards as articles for gliding down a snow covered slope making long curving turns, where tips and tails would be as stiff as the middle core. But now, the boards are jumped into the air, launching from half pipes edges and sliding down steel rails, requiring different flex contours. Snowboards are now required to be very flexible yet elastic being required to bend convexly and concavely, yet springing back to their shape immediately, with some riders wanting stiff tips or soft tails or a combination of both.
