Lay flat on your back in the water with the handle pulled tight to your stomach. Bend your knees so your feet are pointing backward on either side of your rear. Keep your knees slightly closer together than your feet at this point. As the boat accelerates to 25 mph, lay back as much as possible and fight to keep the handle on your stomach. The goal is to slide on your rear with the tops of your feet skimming the water — your knees should never actually touch the water.
