Known as ThunderCat Racing around the world, Superlight Tunnel Boat races are unlike any other race event in the APBA. These catamaran-style inflatable boats can race in rough waters that other categories could never dream of participating in. Want to see some air time and crazy maneuvering? Look no further. Each boat in this series carries a specifically designated driver and co-driver, with the driver handling the throttle and steering while the co-driver shifts his or her weight around the boat to keep it stable. Join the Fun – Race SLT.
