How Ballast Bags Work

Ballast bags are vinyl bladders that fill with water to add weight to your boat in specific locations like the bow, ski lockers, rear seats, or trunk. Compared to lead ballast, water bags can be drained for storage and transport, allow you to adjust weight on the fly, and don't permanently add weight that affects fuel economy when you're not riding. Most boats use a combination of factory hard ballast tanks and aftermarket bags to reach the weight needed for a good surf or wake.
