Jet Boats
If you watch television, look on the Internet, or open a wakeboard or waterski magazine, you will see the jet boat manufacturers trying to break into the wakeboarding market. They have introduced several boats over the past few years with towers and wakeboard racks as options. These boats are marketed toward the wakeboard boat buyer, but, due to the jet propulsion, this type of boat cannot produce the characteristics in wake shape and size that a wakeboarder craves. The wake that a jet boat leaves behind is usually very soft and washy. The lack of a rudder makes most jet boats very hard to drive in a straight line when an average-sized wakeboarder is behind the boat carving around.
