Three riders sit on a 78 by 71 inch platform that stands only 10 inches tall, a low deck that doubles as a floating lounge once the boat cuts its engine. The U-shaped streamline profile smooths the ride behind a tow rope, and stabilizer fins under the hull limit side-to-side wander. Boston valves inflate and deflate quickly while the second valve on each chamber adds sealing margin, and the bottom drainage system sheds water that would otherwise add drag. Combined load capacity is 510 pounds for riders over 14 years old. A 900D nylon cover over the PVC bladder handles the scuffing that comes with three people climbing on and off, and foam-padded grab handles give each rider a hold. Recommended rope length is 50 to 65 feet with 3350 pounds of tensile strength; keep speed at or under 20 mph.
