How does flex affect water skis?
Water ski size is often described using the term “ampliation,” which is abbreviated as AMP. Water ski equipment maker Goode has developed a water ski size chart that assigns an AMP number based on your height and weight.
Based on the Goode guide, a skier who is six feet tall and weighs 200 pounds has an AMP number of 220. This number corresponds to a recommended water ski size of 67 inches, with a medium amount of flex. By contrast, a skier who is five feet tall and weighs 100 pounds has an AMP number of 90, which corresponds to a water ski size of 62 inches, with a medium amount of flex. The more flex that water skis have, the more tightly they turn, but less flexible water skis provide more stability when crossing the wake.
Remember that sizing charts such as the Goode guide are meant as guidelines, and you might prefer a slightly longer or shorter water ski size, or a greater or lesser degree of flex based on your experience level.
