Break the sound barrier with this revolutionary tube design from Connelly. The Mach 3 is constructed with a segmented bottom hull that reduces surface area by over 50%. This innovative feature reduces overall drag and increases total velocity. Riders quickly skim across the water and skip over rollers with ease. Features 420-denier nylon cover, 28-gauge PVC bladder, 6 padded handles, Boston valve, quick-connect tow hook, and covered mesh bottom for draining. 510-lb. weight capacity. 80" diameter deflated.
The Boston Valve is a screw-on, two-way valve. The bottom portion is screwed into the towable, while the top is screwed open for inflation and then tightened after inflation. Air is easily released by unscrewing the base connector. It's important not to miss a thread when screwing in the Boston Valve as it may cause the tube to slowly leak air. Boston Valves can be replaced easily.
