Overview Midlength / Utility Range Slater Designs Boss Up Volcanic I-Bolic Model The Boss Up by Slater Designs is the bigger brother of the famous S Boss, marking Kelly Slater's first-ever signature midlength template. Designed by master shaper Dan Mann in partnership with Kelly Slater and Kevin Schulz, this utility midlength stands as the most well-rounded and versatile shape in the entire Slater Designs range. It is a true cross-over craft, engineered to cruise effortlessly across weak wave faces while maintaining the technical capability to grind through cavernous overhead tubes. If you could only bring one board with you on a trip, the Boss Up is the definitive one-board travel quiver. It bridges the gap between high-volume paddling ease and maximum high-performance capability, packaged into a purely versatile silhouette. Built with premium Volcanic I-Bolic technology, the board combines the advanced structural strength and spring-back flex of the I-Bolic core with a natural, heavy-duty volcanic basalt lamination, smoothing out chatter and offering elite responsiveness. This model is best suited for surfers looking for a highly adaptable, high-performance midlength that completely eliminates guesswork in changing conditions. To unlock its full performance potential, it is highly recommended to ride the Boss Up roughly +13 liters more volume than your standard shortboard, paired with the KS1 5-fin template configured strictly as a quad. Model Outline Refined utility midlength outline featuring a balanced distribution of volume to maximize paddle power, effortless glide, and early wave entry. The template blends sleek, continuous performance curves with a highly functional tail block, a configuration engineered to handle the speed of serious barrels while keeping the board loose and free-flowing in smaller surf. Bottom Contours High-performance quad configuration The hull and rocker profile are explicitly designed to harness the speed, lift, and drive of a quad setup. Working together with the responsive flex memory of the Volcanic I-Bolic construction, the bottom contours ensure seamless, ultra-fluid rail-to-rail transitions and rock-solid edge hold, allowing you to draw stylish, high-speed lines or crack critical turns with total confidence.
