BLOWSION Stand-up Tubbie MIII Race Hull Sponsons

We asked our riders and customers...we got a lot of feed back... we listened. Introducing the Tubbie MIII. We call it the SlimPhast Sponson. Not a cheap plastic ripoff copy but the real deal.

With this Blowsion patented two-plane technology we have slimmed, trimmed and re-defined the patented Tubbie two-plane shape specifically to accommodate the already WIDE footprint of newer stand-up hulls. This allows the hull to sit slightly deeper in the water, while still giving the ski the well known benefits of the Tubbies aggressive turning, hook up and bow buoyancy. This, all without creating too much floatation and side to side instability at mid speeds. We have found with the addition of the Tubbie MIII the ski is much less fatiguing to the racer as it becomes easier to maneuver around the course on long motos. Like the Tubbie I and II, the Tubbie MIII is a win-win benefit to any rider or ski, but the Tubbie III is made specifically with the aggressive racer in mind. Each set available in white or black gel coat and includes detailed installation instructions and all stainless hardware. Patent Pending # 60/509.114.
