The B.O.B. Grind wakeboard features next generation construction with a shape that incorporates Liquid Force's performance paradigm. This offering includes an innovative core, construction process, and design features that make your board come alive. A thin profile CNC all wood core is the heart. Next it's wrapped in a lightweight glass layup for the ultimate in responsive flex. Then it's finished with a see-through graphic to show the beauty within the board. If you're like Bob Soven and you've been waiting for that wake charging ride, your wait is officially over! Features a thinner profile and lively flex pattern. Progressive, 5-stage rocker gives you extra straight-up kick off the wake without the braking effect of a traditional 3-stage bottom curve. LF internal Liquid Rail is an elastomeric sidewall which encloses the core of the board for increased durability and sidewall strength. Single-to-double Venturi concave hull shape lets water speed through a wide center concave into compressing dual outboard concaves that accelerate flow for extra boost. Edge channels through the center of the B.O.B. board provide extra control. Grind base is specially designed for the rough rail rides at the park.
