Suggested board specs for performance surfing:
Height: 2-3″ shorter than yourself
Width: About the width of your shoulders
Bottom contours: Single to double to v
Rocker: Medium / performance
For bigger waves go head height or longer and slightly thinner with a single concave or a single with a double.
This is a great board for performance surfing in all conditions. Extra width throughout the board and the wideness of the tail = loads of speed, whilst the rounded squash tail provides smooth but drivey turns.
These boards will be shaped with 50/50 performance rails
