Born at home to parents Paul and Joanne in Fort Pierce, Florida, a rough-edged, redneck fishing town with a consistent beachbreak, Sebastian was named after the famous inlet just an hour up the coast. The Zietz family loaded up and moved to Kauai where they quickly became embedded into the Hanalei culture. If you have never seen Hanalei Bay, allow me to constrict a picture: it’s a tiny hippy town nestled into the nook of a lush and verdant valley located nearby several distinct and potentially world-class waves. Although still a pre-teen, his parents sailed down the Florida coast where Seabass spent time with shaper Charles Williams . But it wasn’t long until the family made their way back to the Garden Isle. The energy was right, and Sebastian’s talent exploded.
In 2007, he won the Goofy vs. Regular event which signaled his arriving at another level. The next year, he took the Macy’s Trifecta Pro Junior, and surf media was beginning to take notice of not just his lightning quick surfing which is equal parts classic carve and new school extravaganza. The same year he topped a stellar field at the Oakley Pro Junior. At this point, YouTube was showcasing not just his exciting surf clips but even an overseas dance off that began building a personality his contest results. His party groove had been struck, and a fan base was building.
In 2012, after a hard fought year on the WQS, he entered the Reef Hawaiian Haleiwa Pro. After facing off with the best surfers in the world, he inched out John John Florence in a four man final and earned qualification for the 2013 ASP World Tour.
