Question: what is the actual physical size of the balloon? Will it block the view of the riders?
Document: The one thing that I noticed that could be consider a down side would be that it limits the drivers view of the riders when they are directly behind the boat/jetski. I am not sure if you are pulling small children and do not want to start fast if you might have a problem as when we attempted to start slow the ball dove. But if you start faster this is not a problem.
It is not just a tow rope that just straightens out all by itself. If you have it laid out correctly (which is easy to do) it works just fine.BTW, it is bigger than you might think. it is the size of a giant beach ball (but shaped as a football).
The size is the key - it holds the rope up out of the water, completely eliminating splash. It also doesn't prevent you from sliding over wake or having as much fun as you would without the ball. I'm very happy I bought it.
Great item keeps rope up out of water and prevents splashing so bad on tube riders. Preformed as advertised  would definitely buy again.
This is quick to inflate and deflate and I like that it makes it obvious to other boats that we are towing. On our pontoon, it keeps the rope up out of the water, reducing spray on the riders.
I bought this to keep the tube from submarining and to keep the tow ropes from going slack in the wake while turning. It does both extremely well. This makes for a much more enjoyable experience for both the riders and the boat driver.I recently pulled a tube behind my jetski without it and regretted it immediately.
Bought this to use behind our 2005 Sea Doo Challenger 180 jet boat. Works exactly as advertised for us:  Keeps that tow line out of the water, resulting in faster planing, less whip, and less spray on the tube riders. Seems to be a nice quality construction as well. I couldn't be more pleased.
I had read mixed reviews about this Booster Ball. I use it behind our Yamaha 23' Jet Boat and it works great. I was never able to get our 3 person tube to consistantly go over the wake without the tow rope getting caught and splashing the riders. This keeps the rope out of the wake. Glad I bought it.
I tow using a &#34;Y&#34; configuration directly off pontoon logs, as others have stated - a very low tow point.This product works fantastic in this application. The row rope stays entirely out of the water once under way, spray into the riders faces has been eliminated (this had been the chief complaint from the kids).Added bonus, my ability to swing the kids back & forth was drastically increased.
We used this all summer and it works great for tubing behind a jet ski. The ball keeps the rope out of the water making the tube move a lot faster. the ball also shields most of the jet spray from the riders ... which they really like. I am thinking about using two of them next year, one at the y connector and one mid way.The ball seems to be pretty durable. We have used it a dozen times and we do not seen any sign of wear.
