The MPH is the latest in HO Sports’ line of patented Sphere Technology towables. Its innovative design isn’t just for looks. Using 3 spheres, the center platform is suspended above the water with only the spheres contacting the surface. This dramatically reduces surface tension and drag behind the boat. The result is a quick sliding, large tube that works equally well on rough or smooth water. The MPH comes equipped with seats for three and a special “step” handle on the side to help riders climb on from the water. Grab an MPH and get ready for the ride!
