ROC SAC Ballast Bags

Free Shipping to Continental U.S.  Fill 'em full of rocks or sand, and slam them into any storage compartment in your boat for a massive wake. Since rock is much denser than water, you get more weight while taking up less space than water bags. NEW: Now you can purchase pre-filled Roc Sacs! We use a dense sand/rock mix, and we’ll ship these filled 45lb bags to you for free, ready to quickly and cleanly go into your boat! Oh - and did we mention that you can load up on Roc Sacs for a fraction of the cost of the other solid-filled ballast bags? Roc Sacs are made out of tough welded PVC material, the same material that commercial river rafts are made out of. This means your boat's interior will be protected from the contents of your Roc Sac as you place it in your boat. This also means that Roc Sac's material is completely waterproof, unlike the soft-covers used on other solid-fill bags which usually end up growing mildew. The comfortable handle is ideally placed for easy maneuvering. B
