A step up surfboard is a board that is larger and generally more advanced than your typical "everyday" surfboard. It's a board that you would "step up" to when the surf gets bigger and more challenging.

Step up boards come in a variety of shapes and sizes, but they tend to be longer and have more volume than your average shortboard. This extra length and volume allows for better paddling and wave-catching ability, which is crucial in larger surf. Step up boards also tend to have a more pronounced curve or "rocker" in the design, which helps with maneuverability in bigger waves.

If you're an intermediate to advanced surfer and you're consistently riding waves in the overhead to double overhead range, a step up board may be a good option for you. It will give you the extra paddle power and stability you need to confidently take on bigger waves.

Additionally, if you're a surfer who is looking to try out new maneuvers and take your surfing to the next level, a step up board can be a great tool. The added length and volume can make it easier to execute turns and perform advanced techniques in larger surf.

Overall, step up surfboards are a great option for intermediate to advanced surfers looking to progress their skills and take on bigger, more challenging surf. So if you're ready to step up your surfing game, consider adding a step up board to your quiver!
