Wakeboard Base Shapes:

Base Material – Nearly all wakeboards are made of either wood core or foam wrapped in fiberglass. Few will be made with graphite, but most likely, it will be fiberglass around foam. They  are cheaper, lighter, last longer, and are more durable, but don’t have the response or lift that wood core wakeboards do.

Channels – Channels are like long extruded fins on the bottom of the wakeboard that helps breakup surface tension

Concaves – Concaves are special dents on the bottom of the wakeboard that help creates lift and reduces suction so the board sits higher in the water

Featureless – Featureless boards have no fins or channels and makes the shape of the wakeboard dictate its performance on the water.

Grind Base – Grind bases were built due to the popularity of rail riding. The base is much stronger and has more durability to withstand the beatdown it gets from riding over PVC, Metal, or docks.

V-Shape Spines – V-Shape Spines are often added to wakeboards with 3-stage rockers to soften landings. They allow you to roll from edge to edge like some v-shaped boats do.
