2020 Straightline Sumo Max 1175 Ballast


Want to add some serious bulk to your wave? The Straight Line Sumo Max 1175 Ballast Bag makes things easy. One of the largest bags on the market at 1175 lbs, this puppy holds a mental amount of water. With a bag this massive you gain a ton of versatility, run it left, right or center depending on what and how you're riding. This system is one of the fastest filling available with 1-1/2" high flow valves and can even tie into your factory ballast. Throw one, two or even three of these in your boat and dial in that perfect wave. The only downside is everyone on the lake is going to want to go for a set behind your boat.
