The Viva wakeboard from Ronix features a sharp center rail for super quick edge transfer into the wake. Rockerline mimics the natural transition of the wake and carries more speed up to the kicker. Sidecut has more contact points in the water, and fin placements allow the board to react quickly to the rider's control. Shallow exit channel helps relieve the pressure from the water. Thin profile reduces swing weight. Includes 4 fiberglass 1.0" fins. Viva 136: 53.5" x 17.1". For riders up to 180 lbs. Viva 140: 55.1" x 17.3". For riders over 170 lbs. Viva 144: 56.7" x 17.5".
