Ballast bags are an essential part of wakeboarding and waterskiing. They are used to add weight to the back of the boat, which helps create a bigger wake. Ballast bags can be filled with either water or sand, and come in a variety of sizes.
Most boats will have built-in ballast tanks that can be filled with water using a hose. However, if your boat doesn't have these tanks, you'll need to use ballast bags. The number and size of ballast bags needed will depend on the size of your boat and how much weight you want to add.
In general, it's best to place ballast bags as low as possible in the boat. This will help keep the center of gravity low and make the boat more stable. It's also important to distribute the weight evenly between the left and right sides of the boat so that it doesn't lean too far in one direction.
If you're using water-filled ballast bags, be sure to place them away from any electronics or electrical components in the boat. Water and electricity don't mix! Sand-filled ballast bags can be placed anywhere since they pose no risk of leaks or electrical shorts.
No matter where you end up placing your ballast bags, always make sure they are secured tightly so that they don't shift around while you're out on the water
