Needing that extra bit of wake to build your wake up or the rear lockers full of gear and need to place ballast elsewhere? A floor ballast bag is a great option for adding a good amount of weight in v-drive boats. Thanks to the bulletproof construction, sitting, standing or walking on the bag is perfectly fine so dont worry about it being in the middle of the boat. This 500 lb ballast bag measures 40 L x 40 W x 8.5 H so it is a good fit in smaller v-drive boats. The bag can be filled and drained using Fly Highs portable Tsunami Pump.
