I have a center ballast that adds 400 lbs. I also have some sacs that are 350 pounds each. The weight capacity of my boat is 2,100 lbs. The boat has large lockers at the back and the sacs go in them. I also have a wake fin that attaches to the side of the boat. We can surf but it is lots of work to get the boat set up for it. My sons ride on the other side of the boat and when switching out we have to move the wake fin and change up the ballasts.
Of course I would want a new Centurion with Ram fill but they are over $100,000 and that is a ridiculous price.
