A stand-up paddleboard is similar to a longboard, but even bigger, wider, thicker and heavier. SUP surfers use a paddle to propel the board across through the water. They typically range from 9′ to 12’ and are also available in inflatable version. Stand-up paddleboards are everywhere. It’s easy to maintain your balance over it and almost unfair to other surfers how easy you can catch a wave using them. They can be used from 1’ to 60’ waves and also be enjoyed in flat water spots, including lakes, rivers, and canals. Did you know that one of the best places to learn SUP is San Diego?
