If you're towing tubes a tow ball float is a must have. It keeps the tow rope up out of the water so that the people in the tube don't get a constant face full of spray. After a season of use it has held up well (looks like new) and I consider it a great purchase.

When using this, it does the job perfectly. Our round extra large tube does not dive into the water when this is attached.; it prevents that from happening. When I did not use it our tube sank twice.Highly recommended

Having towed using the jet ski with and with the booster ball, there is a massive difference in drag reduction using the ball. It also helps in keeping the rope outstretched, preventing it from being sucked into the engine. The product itself is great quality.

Actually reduces rope drag on the boat noticeably, very happy with the performance of this product and is very robust.

This ball does exactly what it says it will do, keep the rope up out of the water on boats with low tow points and reduce the water spray in the eyes of the towable riders. It also greatly reduces the chance of submarining the towable, notice I did not say illuminates. Driver and rider experience has a lot to do with submarining too. Perfect and very well made.We tow the Big Mable couch style and chariot style with absolutely no issue (chariot style requires riders to distribute wait to rear until getting going, slow does not work well but haven't found a rider yet that wants to go slow chariot style anyway) behind a 23' pontoon with a 115 hp motor with tow points on the rear of the pontoons (maybe 1 to 1-1/2' max above water line).Prior to the ball I found it difficult to get a donut style, single rider tube outside the wake (even had a hotdog son that would stand on it and taunt me to knock him off) and my wife did nothing but complain about the rope spray in her eyes. Then I bought a Big Mable (two rider) tube and NEVER got it out of the wake, my adult sons (5 of them all over 23 yrs old) did nothing but complain that tubing behind a pontoon was for grandma's and would rather just anchor and swim.Then along came "the ball" (as we call it)!! Rope spray has become a non-issue for two reasons; 1) it is greatly reduced and 2) riders are too busy trying to stay on the tube (remember those 5 sons? LOL They now spend a lot of time and energy crawling back up on the tube! No matter which tube I am pulling and no matter couch direction or chariot direction, my pontoon is no longer being called a "grandma" boat). "The ball" now allows the tube to EASILY get outside the wake left and right and it kind of rolls across the water allowing for the exciting sliding of the tube left and right but keeping the rope taught so the severe rope snap is gone and no more whip lash! You want air?My wife refuses to ride chariot style after watching the boys but does get on couch style (grandma) and has not once complained of rope spray but then she is hanging on for dear life and exhausted when her turn is over so she's just laughing, smiling and too tired to complain of anything unless it's having to get off or going too fast! She has started riding more with the grandkids now because I won't try to dump them (they too will age and the ride will change! All in due time!).As for those that are experiencing the ball coming unzipped? Duh, turn it 180 degrees so that as the water is pushing the zipper up or so that it is being zipped up instead of being unzipped (or zipped down) by the water movement, seems like common sense to me! Have had absolutely no issues with it unzipping, just be conscience of what direction you are attaching it.Saw people complain of the size, really? Deflate it when you bring it in the boat, takes it less than 2 minutes to deflate (just be careful with the valve cause the inner bladder will move and the valve can be hard to find to inflate again, I hold onto the valve until it's totally deflated and folded up). Want to use it again, pull out your 12v air pump (Airhead AHP 12v High Output air pump) and wala in less than 3 minutes it's full once again. We store it under our small corner seat cushion on the pontoon with our ropes, takes up very little space.This was the best purchase since we bought the pontoon! Makes tubing with a pontoon viable and the tubes as exciting and fun as they are designed to be! I would have given this ball 100 stars if that was an option! If your having similar problems as I had just buy it and use you head when attaching and using it!Highly recommended! Take it from someone with 5 boys ages 23 to 39 that can make them all scream and yell during the ride, make them need to climb back on the tube many times in an hour and make them all complain of very sore muscles the next day! The grandkids not so much but as I said, they will age and the ride will change.Enjoy and safe boating!!
