Your motorboat will bring you out from the pier, and then you will enter the water. You will move into a squatting position, leaning backward. Using the boat itself for help, you will affix your skis. You will then grab the tow rope and wait.
Unlike snow skiing, where you start standing up or push yourself up, you will wait for the boat to pull you up. We will show you how to position your body and arms to do that, of course.
Once the motorboat is accelerating and you are standing, all you have to do is enjoy the ride! If you should fall, don't worry. You will be wearing a life jacket, and a spotter onboard the boat will signal the captain to turn around and pick you up. You will then affix your skis and try again!
