Flexible Ballast To Dial in the Perfect Wave
Supplement your boat's ballast with Roc Sac ballast bags to boost your wave height and fine tune the shape. Fits easily in storage compartments, lockers, and under seats. Easily move bags to locate weight where it's needed most. No more shuffling friends and family around the boat.
Buy Pre-Filled or Empty
Hit the easy button and buy pre-filled or buy empty and fill with sand, rocks, steel shot, or other fill material of your choice. Leave your filled Roc Sac ballast bags in your boat for convenience. Towing long distance and don't want to haul extra weight? No problem, bring empty bags and fill with sand or rocks at the lake.
Flexible Fill Options
Fill with your choice of material. Weight will vary from about 40 lbs (sand, gravel) to much heavier based on the fill material. The pre-filled option weighs in at 45 lbs and comes loaded with a dense sand/gravel mix.
Wide, Easy-fill Opening
Filling is a cinch with Roc Sac's wide-mouth opening. Fill in seconds by hand or with a shovel. Emptying the contents is quick and easy too.
Easy & Secure Roll-top Closure
The easy-close roll top seals securely with hook & loop strips, keeping the contents contained and your boat clean. New for 2023, the roll top is even longer resulting in more rolls and fully leak-proof seal!
Premium Waterproof Material
Made with ultra-tough 22oz PVC coated polyester fabric. Fabric is waterproof and UV resistant. Won’t mildew like other uncoated fabric ballast bags. Heat welded seams are strong and water tight. Built to last.
Compact and Low Profile
Easily stows away in lockers, under seat cushions, or anywhere you've got a little empty space. A filled Roc Sac is about 14" x 12" x 3". Designed to keep its low-profile shape, even after filling.
Tough Carry Handle
Nylon webbing handle is durable, comfortable, strong, and optimally placed for easy maneuvering.
