Personal watercraft (PWC), are also known as “water scooters.” The Hydrorunner is advertised as being one a DIY person can build themselves from plans.
The Hydrorunner features a small pair of outriggers. And a powerful motor, of course.
Pretty neat. An excerpt from the plan sales page reads as follows:
Build this high-performance personal watercraft and power it with an outboard engine. It was featured in Popular Mechanics magazine. Makes a great father/son project.
At rest, HydroRunner sits low in the water like a Cheetah poised in deep grass. Squeeze off a handful of throttle and she leaps onto plane and skims across the water at 40 mph. On plane, the tunnel-hull design gives a sure-footed stability that is unmatched by PWCs with conventional V-hulls. Turns are flat like a hydroplane. Stability comes from the super-wide beam, which is camouflaged by her patented tri-hull design.
