In its earliest incarnations, stand-up paddleboarding wasn't a sport. It was just something surfers in Hawaii did to reach far-away waves or cross huge hotel bathtubs. Over time, the practice evolved into an activity in its own right, and one of the fastest-growing water sports in the world. The team at Island Paddle is fully on top of the trend, hosting 5K SUP races. Of course, man cannot live on stand-up paddle-boards alone, so the team outfits folks with all manner of self-propelled aquatic vehicles, including kayaks. They even have the water crafts delivered so patrons can row their boards on whichever waves they like.
