Since you have a Centurion, you will likely get a better wake on the left, the regular side. Most boats surf best at 10 mph. Since most boat speedometers are horribly inaccurate, set your speed to where the wave looks best when no one is riding. Properly ballasted, you should be able to build a crisp wave with a curl.

Finding the "sweetspot" for your ride takes time and patience. It is largely dependent upon the size and volume of the wave, your weight, and what board you are on.
