The O'Brien Turmoil 4 Towable Tube is a great ride for up to four riders. This versatile tube can be pulled in two different directions so your riders can kneel and enjoy the ride or sit back and relax for a leisurely ride around the water. There are a ton of handles so the riders have plenty of choices when it comes to holding on. With a weight capacity of 680 pounds, the materials on the Turmoil must be incredibly durable and strong so O'Brien used a 30 Gauge PVC and Fully Covered 840 D Nylon to ensure the integrity of the tube. When you want to entertain lots of guests then you'll want to have the O'Brien Turmoil 4 Towable Tube attached to your boat. [+]
