The Sister Series from WOW takes the deck tube to a whole new level. We took the standard deck tube construction that has been thrilling riders for more than 3 decades and added interactive secure seating with high visibility risers. This interactive secure seating has been incorporated into 4 different shapes each with their own personality and look that we call the Sisters. Choose from Ruby, Zelda, Trinity, or Tootsie. Each has at least 2 different tow points and can be ridden while standing, sitting, kneeling, or laying down. The new interactive seating design also makes the Sisters perfect for using as a lounge or an island. Trinity ? 1 to 4 person with 3 towing directions.
