Mike, there are two different styles, and different board 'classes' designed around those styles, along with a few hybrids or boards attempting to emulate both styles.
Skim boards are skim boards, and in fact often differ very little from your typical ocean skim board. Skim style is more about surface rotations and ollie influenced maneuvers. It is not always super clear cut, but for these purposes we will draw a clear line.
Surf style boards, tend to be more like a performance ocean shortboard, but a good surf style wakesurf board, actually differs quite a bit from an ocean surfboard. Nevertheless, surf style is more about hard carves, and exaggerated above the lip maneuvers.
The volt is fine, and you will likely be happy with it, once you have the basics down then decide if you like surf style or skim style better.
