Airhead BOB 4-Rider Towable Tube Tow Rope 60 ft Inflatable Buoy Booster Ball 4100 lb Blue

[This review was collected as part of a promotion.] When I was a kid and getting pulled behind a boat, we never had one of these and it became a pain in the neck at times when the tube would go under the water. It was a lot less fun when you had to use your strength to keep the front of the tube up as well as trying to hold on around turns and figure 8s. Now that I am the adult driving the boat, I knew there had to be a better way, and this is it. We bought one of these booster balls and it completely eliminates that issue. The kids just hold on and have fun without ever a second thought of the tube sinking under from the pull of the boat. If you have a ski tower, you probably don't have to worry about it, but my boat does not have one, so we definitely needed it.
