Many people understand that smaller and/or lighter riders tend to have smaller feet and/or a lighter/lower leverage point and therefore they prefer narrower tails and they can also handle shorter boards. Taller and/or heavier riders with bigger feet and/or longer legs have a higher/heavier leverage point and tend to prefer a bit of extra board length and tail width to support their weight and power on the tail.

A similar principle also applies to sailing level. Pro’s who drive their turns over the front foot and steer with the back, tend to opt for shorter shapes so they can carve short radiuses and close the turn over the narrow tail. Novice wave riders focus more on their back foot and need added width in the tail to support the additional force they exert over the tail so they don’t lose too much speed during the turn. A little bit of additional length also helps novices to float around and tackle any white water.

Available in two constructions:

GET: High Flex / Low Torsion Deck: Biax Carbon, Bottom: Fibreglass

GBM: Medium Flex / Medium Torsion Deck & Bottom: Carbon/Kevlar

Analysis of the above leads us to the conclusion that there is a need for two board shapes. One that is shorter with a narrower tail and another with a bit of extra length and more width in the tail. Both board shapes can be designed to an optimum performance ratio between early planing, acceleration, speed and turning ability regardless of the fin setup.
