The Shock is the perfect rube for relaxed cruising and adrenaline rushes. Boost employs HO's new tapered "cronut" design with two tow attachment points on opposite ends of the tube. Sit or lie down on this towable, and enjoy the wild ride. Features Boston valves for quick inflation/deflation, no-show handles, 2 quick-connects, and ergonomic seat for better neck position during rides. 170-lb. weight capacity. 50" diameter.
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.
