for info and pictures on goofy side ballast. You are likely to need to fill the ballast on the right and the front ballast. You may need additional weight. The easiest way to test this if you don't have fat sacs is 30 gallon plastic garbage cans. They weigh about 250 pounds when full of water and can be returned for a refund when you are through with them. For testing weight in lockers, 5 gallon buckets weigh about 40 pounds each. One of the keys to building your ideal wake is to test. Test numerous configurations and then try to fine tune it. For additional ballast info, go to: www.HowToWakeSurf.com
