Waterskiing and wakeboarding are two popular water-sports. Finding a model that best suits your intended needs, whether it is a waterskiing, wakeboarding, or general boating, can be a difficult task. WaterSki magazine did extensive testing for 88 boats and provided a wide variety of information to help consumers select the best boat. A portion of the data they reported for 20 boats with a length of between 20 and 22 feet follows (WaterSki, January/February 2006). Beam is the maximum width of the boat, HP is the horsepower of the boat's engine, and TopSpeed is the top speed in miles per hour (mph).
