Is this longboard suitable for smaller surf?

Hey all,
Looking to get a longboard for small / mushy summer waves as well as for when I feel like I need to go bigger to practice fundamentals and found this one at a decent price. Seems to be pretty narrow and thin for a longboard at 21 1/4" and 2 5/8". I've asked for pics of the rocker. What do you guys think? Is this geared towards bigger / steeper waves?
