New jet-powered surfboards will add between 6 and 10 knots to your speed in water, along with 14 pounds of extra weight, which is not always a bad thing in the water. The extra speed when surfing seems a bit unnecessary with the kinetic energy of a wave, but if one were interested in paddling a long distance, either to surf a specific spot that has no beach access or to make it out past impossible breakers, this PWP (personal water-propulsion) device may come in handy.
