It affects how high the wakeboard sits in the water.
wikipedia further explains:
there are three places to check wakeboard widths: tips and tails - those are generally the same - and in the middle. Narrower tips and tails sit lower and make the wakeboard turn more aggressively. Wider tips and tails allow for more surface tricks, and a better release for spins off the wake. However, the main variable that changes with the width of the middle of the wakeboard is the height that can be gained off the water - the wider the middle of the board, the higher it will sit in the water and the harder it will bounce off the wake.

Wakeboard towers are typically made from either stainless steel or aircraft grade aluminum tubing.

A wakeboard tower allows your boat to have more hang time, it can be used for extra space to put wakeboard equipment (ie. racks, speakers), and it can be served for support when walking around the boat.

to first get the wakeboarder up and out of the water, punch the throttle. once he is up, the drag is quickly reduced. then you should basically just play with speed and trim until you get the boat planing and get the wake as big as possible
