The Rusty Surfboards Underbite 4’8 Wakesurfer isRusty’s fastest, loosest wakesurf board design yet. It has a curvy outline with a wide thumb tail. The tail is steep and very hard, giving it good, quick release off the lip with a slight vee off the tail for a smooth finish to turns. The rails are more thin up front, but still forgiving. The apex of the rocker is moved up to move the curve more forward, straighten the rear, and increase the planing of the board. Get on the UndeR.bite and you wont want to get off!
